I definitely underestimated how good this pedal would be on my board which I use in a cover band. I bought the OCD at about the same time I bought an EVH 5150 pedal thinking I would use the 5150 for heavier songs (Van Halen, Metallica, Ozzy, 90's grunge) and the OCD for lighter material (80's pop, 70's rock). I absolutely now use the OCD on the heavy material as well as the lighter songs when overdrive is needed. I set the HP switch to on, Vol at 8:30AM, Drive at 2:00PM, and Tone at 3:00PM.

At very reasonable stage volume with a mic in front of a Celestion Vintage 30 speaker, songs like Enter Sandman, Unchained, and Interstate Love Song sound fantastic with this pedal because you don't lose the musicality of each note and you retain the power of the chords because you aren't losing tone to saturation/distortion.

I'm getting great results with a DiMarzio FRED humbucker in one guitar and an EVH Wolfgang Bridge humbucker in another. String harmonics and pinch harmonics all sound musical. I use TC Electronic buffers going into and out of the board, and a Keeley compressor that is always on before any pedals. I'm using a Fender Hot Rod Deluxe 40W amp.

Even though my bandmates rip on me for having a big pedalboard, my interest in digital modeling to replace this setup is almost zero because old school pedals sound so good when you take your time and dial everything in.

The OCD is and will as be an industry standard in regards to overdrives.It sta ks well, it is awesome as a boost w/ the gain reduced, however it does compare to V1.7. The earliest versions were better period. I may consider the custom shop one (V1.4). I will always regret getting rid of the V1.

Fulltone pedals are always bulletproof, but this one is bulletproof and dialed in. Amazing tone for my Fenders, Charvels, and Les Paul's. The tones are so broad and saturated, gain is clean, but can be dialed back to just add warmth, and surprisingly very volume knob responsive. Worth every penny.

The OCD pedal is amazing. Even when the drive is at ten, you still get clarity and definition with each note. I have many overdrive pedals and the OCD is now my go to pedal. This pedal is worth every cent of the cost. Highly recommend this to all guitarists.

If I had one OD/distortion pedal to have, it would be this one. There is full range of tones making this extremely versatile and big sounding. You have a lot of tone control with the knobs! Distortion retains clarity even as you turn up the saturation. I especially enjoy the warmth of the tone with this pedal. Whether you have a light amount of gain or fully cranked, the sound is never harsh or unusable. Just excellent all around!

The Fulltone OCD pedal review I found this pedal to be very noisy and the gain is just okay. It was on my pedal board for a few hours, I tried it through various amps, (mostly Marshalls, Plexi heads, JCM 900 and 1974 combo) I did not like the results. I wasn't blown away by the gain or the tone. I was disappointed overall by this pedal, and it wasn't cheap either.

Been playing mine for years, has the sound that I'd always looked for. Tried many pedals but nothing matched my OCD. Highly recommend !

Does everything it's supposed to do.
Heavy sounding pedal

Awesome tone and great response to how hard you pick; beautifull harmonic feedback!!!! Love it!!!

It doesn't do anything exceptional and it's sitting on a shelf on my pedal library because I'm too lazy to sell it on Reverb and Guitar Center won't take it in on a trade because the owner of the Fulltone offended a bunch of people by adding his voice to the unpleasant noise that is current American politics. It works best for me in front of a few Synergy preamps but it's not adding anything to my Kemper profiles or Neural plugins. I'm just recording right now and I'm getting my best tones from software emulations and profiling, so much easier to dial in a wide range of tones. If I were dialing in tube amps and circling a speaker cone with an SM57 I might have a different opinion but this guy is just sitting there next to an old Tube Screamer on the shelf collecting dust…

This was the first and only pedal I used for a few rock songs. Love it.

One of the best values out there. As a listener, performer and producer, I've never been disappointed with this pedal.

I owned a OCD many years after having first having couple of TS-808/ 909s; For me OCD wasn't as Clean as I needed,But Istill use a OCD, when needed because it does give my more sustained distortion effect.

Straight outta the box this was a total let-down.
Too much bass, too much mid. Not enough boost, wayyy too much on the volume. Played it less than 5 minutes. It's for sale right now.

Killer tone and drive while maintaining transparency. Very cool pedal!

Crunch from your fender amp on tap

This pedal really beefed up my Blues Deluxe amp. Very well made, reliable, and able to achieve a good amount of good tones.

Awesome pedal, works great with my Marshall!!!

I wish I would have tried this pedal 10 years ago. This is the tone I've been searching for. It does everything from AC/DC crunch to full on metal. I use it with an MXR EQ pedal into a Peavey Classic 30. It's just perfect. Very transparent, very usable drive control, and the tone control actually makes a big difference. Together with a quality EQ pedal you should be able to get any tone with any level of distortion you need.

there is limited volume control on my pedal. I can barely use 1 to 2 on the knob and it gets too loud. maybe I just got a lemon, but I'm afraid to try another one.

I love the new version of the classic OCD.
Whatever Mike Fuller did to this new OCD,he out did himself. This thing sounds great. Its louder, more gain and dynamics. The ability to switch from true bypass to buffered bypass is such a great option.

Just a quick review for the Fulltone OCD. I play a tele running through either a Bugera 5W tube amp, or PodGo playing out. The OCD distortion was recommended to me, and while I haven't owned many other pedals I have heard a few guitars & rigs. Let's just say the tone you're going for is in this pedal. It somehow captures the warmth and fullness of your guitar, and you can slowly dial in the grit from slight breakup to full on dirt. My tele will growl on the low end but the really sweet spot is the slight breakup in the mid and high register notes. This pedal just sings without ever being shrill or harsh. The volume knob is super helpful so you can dial in, then click on distortion without having your signal go crazy loud in the mix, which is important live or in a band. If you want rich distortion that sounds like YOUR guitar and YOUR playing the OCD is it. On a side note, the PodGo does offer an OCD pedal block in the distortion options, but it's no comparison. The actual pedal is WAY better, and worth running your pedal into the PodGo signal chain. You can't recreate the OCD tone on a modeler... not even close. Props to my sales guy, Danny Mosco. Super cool fellow player who took time to answer my questions. First purchase from Sweetwater and I'm impressed.

This was a worthy addition to my collection of OD pedals. It isn't as bright as my Screamer or Paisley, isn't as warm as my CamelToe, or isn't as touch sensitive as my Archer. But on my Fender style amps, has solid mid range punch that I didn't have..

Have used the Ibanez tube screamer and Boss super overdrive for years but this one I'm really happy with. Sounds great and has awesome bite and warmth to it and the switch in HP selection pushes my amp to its max and brings out some really great overdrive tones. I just use the HP selection when on my amp clean channel and sounds great, perfect amount of gain and drive. Then I use the LP mode with a bit less drive to push my amp dirty channel when needing some really aggressive hard rock/metal tones.

This pedal has been on my want list for over a year . I have heard many You Tube video reviews and I liked most of them . But for some reason I just kept pushing it down the list . Now I can say it's the best Drive pedal that I own . And I have only scratched the surface of what it can do . This is an amazing pedal , so don't wait as long as I had , and give one a try .

Hands down, THE best, overdrive on the planet. Period. Seriously, look no further if you could have only ONE overdrive pedal (but who wants just one? ), this would be it. This is a desert island overdrive if there ever was one. Unmatched in tone and quality. Unbelievable build quality.

This is the first overdrive I've ever owned besides the one in the amp and this will be the last overdrive pedal I own it is that good I love it I use it constantly there isn't a day I don't use this pedal

Like others have commented her, I too have been in search of an OD that drives but does not dominate the valves in y Egnater Rebel 30.

OCD does the job, brilliantly! I've got it set with Volume at 9 o'clock and Drive and Tone at 1... the break-up is sweet, some grit and toasty... god it sounds great!

Also with the switch at LP, I have a compressor straight after the buffer/tuner into a harmonist and then the OCD.

Very impressed and very happy!

Thanks again Ashton Boyd and the Sweetwater crew!

Seriously... I've tried dozens of overdrive pedals. If I would have purchased an OCD to begin with, I could have avoided a lot of expense and frustration. Also- run it at 18v and thank me later.

I love the sound of this pedal. It comes close to the sound of overdriven power tubes and the pedal is very touch sensitive. It cleans up well with the volume pot on your guitar. The build quality of this pedal is top notch ---- really well made. I own two Fulltone pedals and am happy with both. I highly recommend this product. I'm using it on a pedal board with a TrueTone OneSpot CS6 power supply.

Not going to bore you with specs on this overdrive pedal keeping it plain and simple I cannot live without it and you may not be able to either once you try it.

I use this with my Marshall Origin 20. The Origin has some great overdrive to it but there are times (as we all know) when you need a bit more. I barely crank the drive knob and get enough distortion / overdrive to add just enough crunch to the overall sound while maintaining clarity - always a ++. Overall sound of the overdrive can be adjusted to your ear via the ton knob - it really changes the drive 'kind' - so a few pedals in one.

Has a good sound but almost compressed, but not bad I enjoy it bet you will too.

I was really excited to get this pedal, but there were a few things off about it. 1 the light was blue instead of red which wasn't a problem but I was confuses. I turned the distortion up all the way and still didn't sound super distorted. It sounded almost like a very weak distortion.

The OCD is by far my favorite OD for heavy tones and solos! Fantastic, smooth drive and natural compression. Be aware that it runs optimally on 18v. It can run on 9v but I was experiencing some buzz even when it wasn't engaged. But man... even at 9v it sounded great. Highly recommended!

Read many reviews before buying this pedal. I was very happy I did. It gave me the mild mid range color I wanted with lots of headroom at 18vdc. Now I can get the sound I want practicing without annoying the neighbors.

Okay first and foremost I dont own an OCD pedal BUT I do use one exclusively twice a week for lead guitar in my churches worship team.

The OCD was never on my radar screen for a pedal (looked too boutique-y) but after using it these last few months, it's almost a must have/consideration to any setup that needs Grit/Dirt/Distortion.

Setup is easy, the distortion can range from gentle breakup to searing, creamy tones etc. Construction is solid and this piece has been rock solid reliable.

I've owned and tried many overdrives. This OCD pedal is in a league of its own! Seriously clean for overdriven crunch. I am dumbfounded by the crystal clear notes and sound that comes out despite the gain and drive being cranked. Sick! You will not be disappointed with this pedal!

I love the tone and drive range of the pedal. I received free next day shipping of the product and a Sweetwater engineer actually called me to make sure I got what I wanted and offer future assistance.

Love it! I noticed that using a boost in front of it caused some audible clipping when turned off while in enhanced bypass mode... So if you use pedals with gain in front of it, you might want to try changing the dip switch to true bypass. It was a slight audible clipping I noticed when recording direct.

All I can say is I don't know if I could ever go back to a Tube Screamer again. This is the best overdrive pedal I've ever heard.

This pedal was outta stock here at Sweetwater...I stayed patient...once in stock...I purchased. I have a vox ac4 with 12" ..and three orange crush amps including a cr60c..my fav btw. I using play my les paul thru the gain channel. I use the ocd as a boost and use it on HP mode...Unbelievable sound I get ! The gain channel on the crush series is very good on it's own, however...a whole different level with the ocd turned on. Boosting my gain channel with the ocd sounds incredible ! There is a reason Orange recommends the ocd for ALL of their amps. Thru a clean channel yes...but I prefer boosting an already dirty amp. How does it improve the gain on my orange ? It tightens it up and gives more saturation..it sounds better, bottom line. If you can't make an ocd work, then you are using it wrong. Look at that price tag, unbelievable pedal and a steal at its given price. Works on my vox very well, but for my vox, I mainly use the Ratt. Get you an ocd, it is a beast !!

This is just the best overdrive pedal out there. It can give you a sparkling transparent tone to a very good slapping lead tone!!

Amazing results from this pedal. I've owned Boss and Ibanez OD pedals and none of them compare to the tone this pedal produces. Love it.

Aptly named, I like it a lot. Still learning how to get clean boost and sometimes growly gain (Larry Carlton), switching between OCD and compressor. There's a lot to explore, and it always makes me want to play more. Works very well with my Marshall DSL 40c .

I like it a lot, not quite clean with drive at zero, but backing off guitar volume cleans up enough. Still experimenting with order of compression, boost/drive, etc. With the compression first is really good. I'm in the jazz/growl group mostly. Still exploring harder tones with drive turned up to 2 o'clock but don't really need separate compression for that. My new favorite pedal. Thanks a lot, Sweetwater.

I played this pedal for nearly a year now before submitting a review. This OCD Overdrive Pedal sounds fantastic run thru the clean channel on my JCM 2000 Dual Super Lead Marshall Amp. It delivers amazing overdrive sounds while playing my Gibson Les Paul Classic, Ibanez, Fender Strat and 5150 guitars. With a flip of the switch the OCD V2's HP/LP (High Peak/Low Peak) switch takes the pedal from a clean boost to next level distortion that sounds amazing. It is now a permanent fixture on my pedal board, and has replaced a previous version of the OCD I had in the past. I am highly satisfied with this purchase.

Very versatile

I like this overdrive, its smooth and easy setup.

The overdrive is great I would recommend also by the power supply

Crunchy lows to screaming highs and all that’s in between.

I recently bought the OCD based largely on customer reviews and was not disappointed. This thing is amazing! It has all of the bite and crunch you need from an overdrive but maintains the tone and clarity of your guitar without making things muddy. The controls are very responsive and give you all of the variations IV overdrive you would need. This is a must for any guitar players arsenal!

I like this pedal quite a bit, I do. I prefer it to, say, the Soulfood, which is a classic, but I feel that with the OCD I don't have play so goddamned loud to get the sound to distort. As a bonus, it will feed back like I don't know what. Yeah, nice.

This pedal, for me, is alright. I struggle getting it to sound great. It sounds KILLER through Orange amps from experience, but I struggle outside of that to get this thing to sound full or present, though a lot of my friends LOVE this pedal and get great sounds out of it. (I'm the same way with PRS guitars, can't stand playing them, love them when other people do)

Awesome, great for punching through a solo.

I have literally owned every single big name vintage & boutique drive pedals and the $100 Fulltone OCD shines over them all. It gives you that sweet overdrive you crave while keeping the sound of your guitar in tact. It sounds great on everything from American Strats & Tele"s to Les Paul Classics and I run it through my Marshall JCM-2000 TSL60, Fender 65 Deluxe Reverb Reissue, Mesa Dual Rectifier & lastly my Vox AC-30TB Handwired reissue and it sounds fantastic on everything. I own tons of pedals and this one is my go-to drive 90% of the time. I highly recommend ALL Fulltone Effects. They are all topnotch and a real value.

Excellent tone and character! It's versatile and transparent! Your original signal isn't altered or "dumbed" down. Get one now. Period!

Bought the newest version of the OCD. Fulltone is always putting out new versions of all his classics. Only thing is, they arent usually better. I"m fact the opposite seems to be the case.

The new OCD is an bass trap. Just a big low mid boost into all the wrong frequencies you don"t want/need in a live mix. And no real way to remove them.

Quick delivery via Davis Snyder! This pedal manages to evoke a warm, fluid sounding overdrive and leaves behind the TS-9 mid blanket. You can also dial back your guitar volume to a rich clean sound with a hint of OD hair - very musical and smooth. Cranking up the drive and hi-peak switch brings you to more distortion territory but still very musical. I've looked at this pedal for a long time but always thought I was set on overdrive. Still - I felt OD could be better and not chop off my high end. I was right!!

I haven't tried any of the older versions of this pedal, so I have no frame of reference to say whether this one is better or worse. However, the pedal definitely delivers on its promise of driving an amp without drastically changing that amp's base tone. It's a very dynamic pedal and responds very well to your guitar's volume or to your picking attack. It does indeed sound like a fully cranked classic tube amp. If you're looking for a pedal that has its own unique sound (like a Tube Screamer), this is not your beast. Whereas the Tube Screamer can actually make a lesser amp sound cool, the OCD is most at home breaking up an already great-sounding amp. But in a really awesome way.

I'm just echoing what most say about this pedal: it's incredible. The range of tones, the ease of use, the "it plays nice with others" factor, the build quality ... How diverse of a pedal is this? I play both guitar and bass. In my main band where I play bass, my guitarist uses his OCD as a great warm overdrive pedal for bluesy stuff. In my other band where I play guitar, my OCD is my "heavy crunch" pedal. But it could easily be my "warm overdrive" pedal too - it does both equally well. Every level of distortion / overdrive you will ever need is right there, and easy to find.

It comes down to this: if you don't have an OCD on your pedal board, you really need to question your validity as a rock guitarist. ;-)

Really clean and really smooth. Nice distortion even with chords—can hear every note!

The BJr with the OCD (drive: 11 o'clock, tone: 11 o'clock, volume: to taste) is a beautiful thing. With the drive all the way down the OCD operates as a slightly crunchy boost. With the drive past 2 o'clock the tone gets a bit flabby but that is a function of the amp bass response, no the pedal. Plenty of sizzle on the pedal. Enjoy.

I use this with a 15w Class A amp and it sounds great. I leave it on most of the time and roll my guitar volume back just a bit to find that sweet spot where I can control breakup with pick attack alone. Then when I want more, I roll the volume knob up. If I could wire this directly into my amp, I would!

Works great! A liitle too much gain for my setup, but, I just carefully set the volume to about 8 o'clock and take care not to bump it. Running on 18 VDC and can"t hear any difference from 9 VDC using Fat 50"s.

Contrary to most reviews, the OCD did not work for me. Too rich in low frequencies and so much volume, almost like another amplifier. What for ? I like an OD pedal that is effective in cutting low frequencies. The Fulltone Full-Drive 1 does it very well and also is able to preserve low freqs when needed, and it has a vast array of tweakable midrange frequencies...

Here's a warm Overdrive Pedal that gives you a lot of versatility. This is definitely a very pronounced pedal with good output that "out powers" all my other Overdrive Pedals. It can be very thick sounding or thinner sounding. So, if your looking for that thick boost to drive your distorted sound further or add some slight thickness to your clean sound in a "pronounced way", then I recommend the OCD Overdrive Pedal. This is a very popular pedal and well admired by many guitarists. I did the research before buying it and it's a definite keeper on my pedalboard.

Ive always had an overdrive +a distortion pedal but now theres an empty space on my board. This pedal will go from od to distortion!! Love it!!

This Overdrice pedal easily beats every other Overdrive pedal I have owned. It is sooo much better than one that I paid twice as much for in 1994, which I still have and is a distant 2nd in terms of rating the 5 Overdrive pedals I own. I have left off a half star as I am waiting to hear the difference in the pedal with the 18 Volt adapter and will up-date If I find the difference significant!
IMO , skip the other pedals out there and do yourself a favor and get the best OVERDRIVE PEDAL ON THE MARKET, the "OCD" by "FULLTONE" ,BUILT IN THE USA, of course.

When I bought this pedal, I really didn't think I'd have it on quite as much as I do. By adjusting the Drive levels between songs, you can dial in just the right amount of warmth - duh, right? Except the sound is better than that I've experienced with other OD pedals. Really happy with this product.

The FULLTONE 'OCD' Foot Pedal is the BEST Over-Drive Pedal I have ever owned and/or used. It just blows away the BOSS DS-1. It even out-classes the IBANEZ MINI-TUBE SCREAMER I have as well. What I did not think possible was that it literally BLEW AWAY my BIXONIC 'EXPANDORA' and it wasn't even close ! and I have not even used the 18Volt feature yet as I a waiting for the 18Volt adapter to get in stock @ SWEETWATER, and I imagine that the improvement will be even better than the tones I get out of this FANTASTIC Pedal already
What I like best is the way the DISTORTION level stays the same not matter what the sound decibal level is, and I want to publicly THANK Don Felder for saying that recently in his Rig-Rindown I read with the free subscription I got for being a SWEETWATER customer.

So, I no longer need any of my other DISTORTION/OD Foot Pedals, I JUST DO NOT NEED THENM ANY LONGER since I got this 'OCD' pedal, but I am thinking of putting the Ibanez Mini-Tube Screamer in front of it as a boost until I get the 18Volt adapter.

If you are looking for an UPGRADE to get to outclass the other foot pedals you have or its your first DISTORTION PEDAL, THIS IS THE ONE TO GET !!! Get the best and forget the rest, I can not find a single genre this pedal can not handle or a pedal that is as good as this one is, and I have tried most pedals out there.....

Love this pedal and love Sweetwater

I own a few overdrive pedals. This is the best. Clarity and control is what makes this stand above the rest.

A great addition to my board. They were sold out last time I had money for it, but I bought the Fultone Freq it also rocks put them togater and WOW!!!

The FULLTONE "OCD" Distortion/Overdrive Pedal is THE HEAVIEST sounding OVERDRIVE PEDAL out there! I conducted a SOUND TEST with the "OCD" next to a BOSS DS-1, BIXONIC "Epandora", IBANEZ MINI-Tube-Screamer as well as built-in OVERDRIVE ON a VOX NIGHTRAIN 15 & MARSHALL DSL 40 Tube AMPS..........all done with levels on all pedals the same, in 3 Different settings, the FULL-TONE "OCD" Pedal had the HEAVIEST TONE/SOUND.......it was VERY CLOSE between the BOSS DS-1and the "OCD" but the FACT is the "OCD" has the HEAVIEST TONE OUT OF THEM ALL....
The "OCD" gets 4 STARS because of the price tag, at 2 1/2 times the price I paid for the BOSS DS-1, the "OCD" can not get a 5 Star rating...even though I paid $225 for the BIXONIC "Expandora" in 1993.
MAKE NO MISTAKE, The FULLTONE "OCD" Pedal is a BAD-*** Pedal.......the casing is solid and the control knobs are the smoothest of any pedal I have ever owned to date.The "MADE IN U.S.A." quality of this pedal is second to none!
As always Patrick Schaefer at SWEETWATER had my order shipped out promptly with no problems!

This pedal is "the boss"!! (Pun intended). Sweetwater is great. Josh, my "go to" guy, is great.

Really really wanted to like this pedal. Great reviews all over the web, I thought I was getting something pretty rad. I got it, plugged it in and was underwhelmed but wasn't discouraged. I played with it, tried tons of settings on the pedal and my fender delux but I could never get it to sound the way I wanted. I really like my drives to blend in with my tone and add that crunch rather than impose a new tone. Everytime I kicked it on I felt like my tone drastically changed. I sold it and went back to my old tube screamer, even though it's not amazing it does a much better job at adding to your tone rather than altering it to a new sound.

Your choice of pickups will have a huge bearing on how you feel about this pedal. I generally play either a Fender Strat or a Godin Session Custom. With the Strat coils, this pedal is good but not great, and you have to find the sweet spot (as with a Tube Screamer). For the Strat I prefer the DOD Looking Glass with its onboard filter. With the Godin (Seymour Duncan '59 neck and proprietary bridge) it sounds fantastic at all settings, and gets surprisingly nasty on the "HP" setting. It will rock as little or as much as you want. This guitar and this pedal sound like they were made for each other. I don't own a Gibson electric, but I'm guessing the OCD would sound fantastic with Gibson humbuckers.

The only true negative I found is that the internal buffer in this version of the OCD allowed for faint background noise to come through the amp. Basically, with the buffer on at volume it sounds like an OCD pedal is turned on loud in the next door neighbor's basement-you can hear the faintest distortion below the clean signal and it's super annoying. Who knows if this is common to all new OCD's or if mine is malfunctioning? The good news is that you can just flip the internal switch to true bypass and it goes away, and then functions like every other true bypass pedal.

Ultimately, the build quality and component quality are great at this price. It feels like a more expensive pedal. I'm impressed, and don't care about the buffer anyway.

Great product and excellent service!

Always have liked the sound of my Orange amp and guitars. Didn't think I was ever going to buy a pedal ever until I saw the OCD on the Orange Amp Official Website. Orange Amps senior amp tech, Jon Bailey, said the OCD is one of the best pedals to use with their amps. It's easy to look up and he also gives advice on how to get the most out of this pedal, I copied pasted his technical article below. So I tried it and really like it. This pedal and an Orange Amp sounds great with my Schecter sustainic, Fender Strat, and Jackson guitars. I would recommend in a heart beat and as always my Sales Engineer, Abraham and Sweetwater for the great business practices, Mark.

"I cannot overstate how great this pedal sounds! From a subtle boost, to a natural overdrive, to full on high gain, it does it all and it does it without killing the natural sound of our amps. My favorite way to run it is with the drive between 10-11 o"clock and the volume pegged to goose the front end of my Retro 50 and make it cry for mercy. I also like to use it in the studio with the clean channel of our amps as a sort of third "in between" sound. The pedal has two modes of operation, high peak and low peak. High peak can give a little more bass and drive, as well as some extra upper midrange if you need to cut through a dense mix. Low peak is your sound only more, without tonal change. A great trick with this pedal is to run it at 18V, which gives it more headroom and a truly "amp-like" feel that responds to your pick attack and volume control just as our amps do naturally. I"ve tried just about every drive pedal out there and I always come back to this. It works, it"s bulletproof, and it"s relatively inexpensive given the quality and flexibility." Jon Bailey, Senior Orange Amp Tech

It has the big band heavy metal sound all the way. The highs are suppressed but excellent in what it does.

I was instantly blow away by this pedal! With the tone and drive controls you can summon up from crystal clean to rich, full distortion with that sweet note suspension. This pedal is extremely well-built, well thought circuitry, and can emulate any distortive sound. You need to check this one out!

There's a reason this pedal has become one of the default overdrive pedals. I'm impressed with its construction and it works like a charm. (This is the new V2 model and incl. an output buffer to keep the sound consistent regardless of other pedal/effects in the signal chain.) I recommend also buying the Fulltone 18V Switching Power Supply for thirty bucks. Of course there are other overdrive pedals out there that will do the job. This does the job as well as or better than any of them. Me, I'm a little OCD, so the name was a plus.

nice addition to my board it adds nice bite and tone and gives my twin a nice push its clean distortion is impressive glad i picked this up!!!!!!

This pedal is the perfect choice for blues rock or metal. The LP/HP controls gives you a lot of tonal options. It is the perfect Marshall in a box. My only complaint is when you are in HP mode and you switch to LP mode there is a slight volume drop. You can probably live with it, just a picky detail.

High quality build and the awesome OCD sound! You cannot go wrong. My Customer Service Rep Damon got my order to me lightning fast too!

After reading overwhelmingly positive reviews, I finally decided to try this pedal. Wow, the sound is so impressive and it creates a rich, responsive, and well-defined tone.

The Drive control can make the sound vary from light overdrive to a medium distortion (not metal distortion or fuzz but a nice, solid distortion). The pedal is extremely responsive to the guitars volume level making it very versatile. This is one of those rare pedals that sound great with almost any guitar and amp. Highly recommended.

I cant say enough good things about this pedal. I couldn't believe how much fatter it made my tone, and i play a usa tele thru a deluxe reverb so it wasn't crap to start with, I find that i just leave this pedal on all the time and use the volume to add a little drive when i play my leads. If you are looking for a awesome tube type tone get it, it will improve your sound 1000%. it is extremely transparent and just does what you think and OD pedal should do and nothing more, doesn't add noise or color your tone. Amazing,

I've had a fulltone fulldrive also, and i prefer this pedal way more.

Okay, so I've had just about every drive pedal on the planet, and my favorites have to be the OCD, and when I need it, Box of Rock by ZVEX. A while back I had a V1.7 that I loved very much, but was stolen from me on tour. Right? Bummer. After that, I went back to the Box of Rock for a while and decided it wasn't doing it for me so I bought a brand new OCD V2. From what I understand there were many circuit "improvements" over the old one so I bought it with the confidence that it would still have that sound that I love.

Not the case...

The newer OCDs have a noticeable lack of clarity on the top end, and instead rely on a more present bottom-end with more headroom for volume and gain. That's cool, and would be great if the pedal didn't sound so darn muddy! The pedal seems to just have this very thick, muddy, fuzzy drive to it that doesn't really have any great dynamics to it, and in general just sounds not that great.

Whatever though, this is just an opinion! I'll probably be taking this one back and picking up a used one second hand.

Pro: Great sound - especially for bass! No loss of low end.

Con: Waaay too much gain. To balance my signal, the volume has to be at 1. There should be an attenuation switch that allows unity at (wherever - 10 o'clock ain't it) or 12 o'clock.

Otherwise, great sound!

Title says it all. If you're considering this pedal, just buy it. You won't be disappointed.

Lots of control! Bought the 18 volt, have plenty of 9s to use.

I really did not like this pedal... Just was not for me or my style of playing...
I expected more.. Just ho - hum... Traded it in...

It’s great on its own, lots of option. But also great for pushing an already overdriven amp

Great pedal! Love the tone and overdrive.

OK, I have a lot of overdrive pedals, I couldn't list them all if I had to. But now I have a Fulltone OCD Obsessive Compulsive Drive pedal and it has definitely earned a spot on my pedalboard. This one is easily the most dynamic pedal of my stable, as it cleans up very nicely when I back off either on attack or with volume control, but unleashes its personality when you push on it. Its overdrive tones are very usable for many styles of music. The Highpass and Lowpass filters are perhaps a bit subtle, but they do alter the voicing a little bit, and would probably be more noticeable in a recording rather than a stage environment. Overall, I am very pleased with the OCD and glad to have it in my lineup.

I love this OCD.

I've owned it for two weeks.
I'm a user of the 90s green Big Muffs for 20+ years and I needed a change. Tried a few good new overdrive pedals and this OCD won.
Compared to the large boxed green Big Muffs, the OCD is not over compressed and it is versatile. You can get a thick heavy sound or roll it back for a bluesier tone.
It's a keeper and most likely going to stay on my main board.

Little tighter breakup than I expected, but a great OD! Stacked it is awesome!

I will write a followup once I've had time to actually test the pedal, but just wanted to let people know - you can order the new V2.0 Fulltone OCD from Sweetwater!! You just have to let your sales rep know that you want the new V2.0 model; they will let their shipping dept. know to send the new one; as they also still have the previous v1.7 in stock for now.

It doesn't indicate it yet on their website, but I just received mine, and it's definitely the newest model that was just released. Thanks to my salesperson Aric B.! This is the OCD with internal switch for true bypass or enhanced bypass / output buffer, and the new Class A configured discrete 2N5457 JFET input section with 1 mega ohm impedance! Totally new - previous OCD has 330k input impedance. Output Impedance = 10k ohms when pedal is switched ON and also when switched OFF while employing "Enhanced Bypass".

Well constructed simple to operate and very responsive, a welcome addition. I've always used only my Amps hot channel for grit, bite, and dirt, and my 25+year old Mesa 50 caliber+ has always delivered but it's good to have options and the OCD has proven itself a great go to pedel alone or to drive the second channel. It took a while because I just stopped using distortion pedals but I love this thing. My names James C Williams aka Blue Jay and blues is my business

I have been searching for the sound that this little box is capable of dishing out for a very long time. A lot of reviews state that the V4 is a total let down, but I can assure you that this box is nothing but sheer delight. A lot of people say it's thin, it's not, scooped, it's not, it's transparent as glass and it doesn't color my sound at all.Why would Mike Fuller degrade an Iconic pedal, so IMHO, as he mentions, he improved it with each version and now he's satisfied with the final version and so am I :)

Also using 18V is a must if you're looking for more headroom and it has a total different feel and sonic character.

I have a V3 clone which is the closest I can get to the actual V3 (I'm from South Africa) and although it is a different sound, I actually prefer this version, although I cannot say if my clone is on par with an actual V3.

The build quality of this unit is superb, the knobs, the switch, the enclosure, everything is just ROCK SOLID, so if you're back and forth about this pedal, stop and pull the trigger, you won't be disappointed, unless you're just not into this type of sound.

If you're looking for an overdrive, your search is over. Stop shopping around and just get the OCD. You'll thank me later. Any sound you need to get out of an overdrive pedal, this thing will do it. I shopped around for a long time, tried several different overdrive pedals but this one just plain does it right regardless of the style you play. Nothing came close to how great this thing sounds and how versatile it is. There are several great overdrives on the market but this thing completely blew me away and still does a year later of having one. I can't find a single flaw with it.

I wanted an overdrive pedal for the extra boost during leads. I found that the volume on this is essential to get the exact tone I want!

This pedal is awesome! If you like smooth drive tones without the Mid Hump and no Bass Loss, this is your pedal. Built like a tank with very high quality components. As usual Fulltone Products are the Best!

I just received this pedal from Sweetwater. I'm totally blown away. The sweet, harmonically rich overdrive is to die for. You can hold a note, and you'll hear upper harmonics ring out. That is awesome. Unity gain is about 11 o'clock, so you have a ton of headroom. I don't use the HP mode because I play through British amps, so HP would be overkill for me. However, for Fender amp users that want a British sound, it's there. The LP mode is very transparent and that's what I want with both my Marshall and Orange amps. As far as overdrive, it's mammoth. You can crank it all the way and still have note clarity. Very dynamic as well. Turn down your guitar volume and it cleans up. Great for blues/rock type of playing. If you turn down the drive all the way and crank the volume, it makes a great boost pedal. However, that takes all the fun out of it. I prefer to crank the gain and let it soar. Yes, it has a ton of gain, but I would not recommend this pedal for metal players. Not that kind of pedal. It has a more classic rock kind of vibe. If you dig Pink Floyd, ZZ Top, Robin Trower, Humble Pie, Free, Zeppelin, Mountain, etc, ... you may dig this pedal. It's groovy!!!

After hearing about this pedal seemingly non-stop the past decade or so, I was skeptical that it could live up to its reputation. I have had numerous opportunities to pull the trigger, but could never justify the $100+ price tag when I already had numerous ODs. Well, a few weeks ago my local shop had 1 used that I picked up for a steal, and I have never been happier to admit that I was completely wrong. This box is as great as everyone and their mother says it is, and as soon as mine gives out, I will be getting a brand new one. There is plenty out there on this boxes tone and capabilities, so I won't focus on that. But as a former OCD detractor, it only took me a few minutes to convert!

Love it been bragging about it

I guess I'm in the minority here as I consider this pedal very ho-hum and lacking in the overdrive department. I was looking for something heavier for Metallica type music. This OCD pedal is more like an Ibanez Tube Screamer.

Maybe i'll be better off using it as an expensive boost pedal :/

I've ran this in front of many amps and it sound phenomenal with every one of them. I'd agree with the general consensus that it's a bit mid scooped but with an MXR 10 band in my effects loop and a little bit of gain there too to push the power tubes it's mind blowing. My favorite amp to use this with is my Friedman Smallbox which you could very well argue doesn't need any pedals because it has got it all built right in but that's why I'm raving about the OCD. I A/Bd this with both the Plexi channel and to a certain point the BE channel and it's comes unbelievably close. It's unreal how similar the dynamics with the touch response are and it's unbelievable how similar it is in its harmonic content and it's the best I've ever heard at how beautiful the note separation on fat chords is and it's the farthest away from the fake digitally processed JCLs that I've tested. Mr. fulltone has achieved something truly remarkable here. I can actually get close to my favorite tones and at bedroom levels, don't get me wrong, I love to open the Smallbox up and push it hard

I set the volume low and the drive high of the OCD and plug it in behind a mesa boogie flex drive at low level and high gain...connect this set up with the guitar in the input of the Mesa boogie pedal and the output from the OCD to a clean channel of your amp.,.just food for thought

Great tone for its low price compared with the infinite "new cool boutique drives" on the market.
Very natural clipping. Good harmonics.
Lot's of gain for an overdrive pedal. Cool.
Cleans up well with guitar's volume roll off. Not the best I've seen but doable.
Tone knob could have a wider range and deliver more treble freqs.
Definitely will do the job for Classic Rock, Blues styles.

I just want to say buy it. You won't regret it!

This is the best overall overdrive pedal. It is a great stack pedal with the Ibanez TS9 and the EHX Soul Food. I even used them stacked with each other. Great Buy!!

This pedal can sound stellar, but in my experience it has to be paired with right right amp and it also needs a bit of a push. Let me explain.

The OCD is a very uncompressed and maybe somewhat scooped-sounding pedal (think Fender Blackface scooped, not heavy metal). That makes for a wonderful rhythm sound with a big bottom and jangly highs. The problem is those characteristics of this pedal need to me smoothed out or they become grating. When I ran this into my Blackstar closed back combo, it was killer. The Blackstar is inherently dark and boxy, so this pedal provided a fantastic sonic sheen with a big bottom surprising for the small combo. When I played in into my Mini Rectifier, it just didn't sound as good. The Mini Rec's cleaner side is sonically very similar to this pedal, so the two didn't blend well. So make sure you have the right amp for this pedal. However, it may work in a more transparent amp if you use a guitar with humbuckers.

This voicing/EQ can be flubby or spiky if you use too much gain, at least with single coils. Low gain sounds fantastic on the OCD, but it's a crunchy sound and not a sustaining lead sound. The best solution I found was pushing the OCD with a pedal that's dark or slightly compressed to get a lead tone. For example, my TS9, Xotic compressor, MXR phaser, and Xotic EP Booster all sounded good in front. Those pedals really tightened up distortion and EQ. My fav was the Xotic EP, which is a highly colored boost. A clean boost into--or after--the OCD didn't do much for me. Also, the impedance of OCD is weird, so it's a bit finicky where it's located in your signal chain. It didn't work after my wha.

In summary, it's a great pedal, but it needs to be paired with the right rig and maybe needs a push if you want to use it for lead work. The OCD also cleans up fairly well. It's a pedal well worth the price.

If you have an amp that has 2 channels and you like playing on channe 2, buy this pedal for a volume boost for your solos. If you have more channels, you can use this pedal as a lead boost on any channel. Simply turn the level as high as it will go & turn the drive all the way down. Put your tone at half way & you have a lead boost that doesn't affect your tone & gives you at least a 2db boost on your volume. This will help your lead solo cut through your band. Perfect boost pedal!

This is the best OD pedal i have ever used. I've had it a few months and it still blows me away. Perfect for a little crunch up to some pretty high gain stuff. The volume is insane, i never have it up past 9 o clock! High pass adds a little more mids and gain. Low pass is your true tone with a little less gain. Definitely worth the money if you're serious about a high quality tone.

I got this to replace the digital Lead channel of my Roland 40w Cube. That amp's Clean channel sounds good but the digitally based amp simulations that make up the Lead channel sound artificial. The analog Fulltone OCD through the Roland's Clean channel sounds vastly better than the digital distortions of the Lead channel. So far, I've been running the OCD at 18 volts. This pedal, along with others I've got or will get, frees me to use the Cube only for the Solid State Clean and to ignore the digital offerings of the amp.

This pedal has a touch sensitive rich and open sound from low to high, quiet to loud. I love it. Makes my amp sound like I opened a door hiding the speaks and let 'all' the sound out.

But more importantly... Don, you have the best reviews, and great personality to go with. I always smile when I check out something and you the guy showing it off. You rock!

Thanks to SWEETWATER staff for consistent help and good products. This is one that will blow you away! A must have.

I love this box. Fat full overdrive. I wish I'd gotten it sooner.

I got this to go with my new Sweetwater Limited Edition Deluxe Reverb. Clean channel volume on 3 and and crank up the OCD and amp starts to growl. It sounds very nice it's a keeper.

Amazing pedal ! I run it with a fender reverb deluxe tube amp and I'm just blown away by the tone and the feel. My Fav pedal for sure ! ! !

Now I see what all the fuss is about. This pedal is awesome!

I have an American Deluxe Strat HSS. Before this I was primarily using a tube screamer mini. While I still like that pedal, this one has taken place as my primary overdrive. I have it set to the hp setting with gain around 2 o clock and man does that make a strat sound beefy, crunchy, and have sweet sustain. The OCD is nicely responsive to your volume knob and pick attack as well. For a lead tone I load the tube screamer with a lower gain setting into this, and magic happens.

Quick summary: worth the price and great sounds on either setting.

Just the right mix of fundamental frequencies and harmonics to make this distortion into ear candy! Even at low volume it's addictive. My new favorite. If you have this and a BB Pre, you have 90% of all the distortion you should need. The high peak setting really makes a great mud-range edgy sound that will cut through. Paired with my Mesa 5/50 Express Plus this is just yummy!

This is the second drive pedal that I have owned, the first being a boss combo drive. I always hated my drive sounds and tried to use the pedal as little as possible. After getting this pedal, I use it as much as I can! There is a smooth quality to this drive that just makes it a pleasure on chords or for leads. The HP and LP settings are great for switching between lead tones and just a little crunch for quieter songs, or just to give more depth to your sound. All in all I am immensely satisfied with this pedal and would recommend it to anyone!

Looked at demos on YouTube comparing other distortion/overdrive peddles, but Don Carr's demo finally convinced me to pull the trigger. Honestly I am still exploring all the tones OCD can produce.Tonal range is huge! This peddle is not a "one trick pony". I highly recommend you get the 18v adapter as it gives the peddle maximum headroom as compared to 9v. As a guitarist who likes to use as few peddles as possible this is a great addition. As always thanks to my contact guy, Ryan Clapper who is very helpful.

Again I have to say Sweetwater customer service is excellent. As well as your photos of gear are typically better then manufacturer's.

I see this pedal on a lot of boards. Now that I bought one, I know why. Many voices in one box! It does get a little ringy turned way up, but they are supposed to. Starting me on a new path of playing, an adventure.

The Fulltone OCD was my first pedal and one the best purchases I have ever made. Although I was hesitant to spend $100+ to just get an overdrive sound, this pedal was more than worth the money. The output is crazy loud, the amount of tones possible seem endless, and the pedal provides a mix of overdrive and distortion in a way that preserves the warm original sound. This pedal can be used for so many types of music to the point where I would say it's a must buy for any intermediate or advanced electric guitar player. Quit hesitating and buy the thing already!

This is absolutely amazing! I couldn't believe the versatility of this pedal. I've gone a long time without an overdrive pedal, and I finally saved up enough and got the OCD. It took about 3 seconds to dial in "my sound". I love the HP and LP controls. LP works really well for rhythm playing and HP has boosted frequencies to stand out more for leads. It has way more volume than you'll ever need (I can barely turn mine above about 11 o'clock). The drive also has a very wide range. You can go from clean boost to mild dirt to pretty decent distortion. The tone knob can wrangle any amp. Keep in mind it only controls the highs, but backing it down can remove any unwanted twang, but turning it all the way up give a nice, warm treble boost without getting ice pick-y. This is one of the best overdrive's you can get, even with all those botique ones included.

I like to have variety of sounds and this OCD does it for me. Good harmonics thru a tube amp also. I'm using this on a small set up for quick setups. It.can substitute my amps overdrive channel with ease.
Sweetwater is awesome to deal with because it's simple and quick transactions keep me coming back.

I was going to buy the Tube Driver. A great pedal, . The sale guy asked me what I was looking for. I explained and he suggested the OCD. I thought he was making fun of me, I said to myself is he saying I am nuts. Then as we spoke it sounded like the Overdrive was what I needed. I waited a few days and it got here fast. I can play crisp twangy to the hard overdrive and I could have it dark to bright. Dud, you can not go wrong for a hand made pedal made in the USA.

Bought this pedal after watching a YouTube video of this guy getting the best tone from a Fender Bassman Amp a Strat and this Pedal total He drip SRV. I was using and had been an ibanez overdrive that green pedal for the past 20 years, let me tell you when I plugged in the OCD I was blown away. Very versatile pedal. I play through a fender deluxe reverb which really has no overdrive or distortion just pure fender cleans this pedal turns it into a monster. My previous amp for 15 years was the Marshall JCM 2000 100 watt head so I needed something to get some drive when I wanted it and also be versatile to play music like the stones or SRV and my Fender now is the champ. i guarantee you will be blown away and live the pedal.

This was my first "real" pedal so I definitely have some sentimental attachment, but I think anyone would be impressed by the sounds you can get out of it. Works great as a clean boost all the way up to some pretty heavy tones that really allow you to ROCK OUT and have a great time. It definitely takes some tweaking to get it to the specific sounds you want (especially if you have a bunch of guitars with different pickups; not every setting is going to sound good) but with three knobs and a switch it is still really simple to use. The sounds you get from this pedal are in that perfect zone between mild breakup and fiery drive, and notes retain tons of clarity even at high-gain settings. It's really well put together too, very sturdy with high-quality parts. The bolts on the side are a great touch, allowing you to take it apart without using any extra tools while still keeping it together really nicely. Overall it's an amazing pedal that gives you great tones at a much lower price than a lot of the "fancier" overdrives out there.

I use this pedal for boosting an Orange Dark Terror. I use it with the gain knob all the way down, the volume at 3:00, and the tone knob at 12. In 9 volt mode it's ok, but you can hear some mudd when going into a gain channel. You need to use it in 18 volt mode. In fact, don't bother buying a overdrive to boost unless it's an 18 volt pedal. You need the higher volt OD pedal to get the guitar signal out of the mudd! I gave it a 4.5 because nothing is perfect.

This is my second experience with a Fulltone product and the overall high caliber of Mike Fuller's products and my satisfaction with them is overwhelming. The OCD took the place of two other pedals on my board and I'm very satisfied with it in every way. It's versatile, quiet, and a real monster when run at 18v. I even appreciate the simple generic black and white cosmetics vs many of the fancy hand painted products on the market. I prefer my artwork to be on the inside of the box not the outside.

I play a very broad array of pickups ranging from vintage Tele single coils to a higher output Nashville Tele setup, P90s, Humbuckers, and even a P90/Single Coil pairing. The OCD works well with all of them and with both my SS and tube amps. It's not my only OD pedal but with it's versatility it certainly could be. In the general scheme of things with OD pedals ranging in cost from $100 to $200 and more the OCD offers terrific value.

As for service I have a brief experience worth mentioning. My pedal arrived on the weekend and it was Sunday before I had an opportunity to try it out. Later that evening I had a question I needed an answer to and sent an email off to Fulltone expecting to hear back on Monday or Tuesday. Within the hour I got a response back from Mike Fuller himself and this was after 10:00 PM on a Sunday night. In my book that's customer service above and beyond the call of duty.

And as always my service from Sweetwater was top shelf. Before Ian McGhee and I even got off the phone the order was processed, packed, and ready for shipment. The pedal arrived two days later. It really doesn't get any better than that!

Exactly what I was looking for. It's great for getting the perfect amount of overdrive on a rhythm guitar part. It's just a really nice pedal. Look at some youTube clips and get a better feel for it yourself. It's the "cleanest" design overdrive pedal I can think of.

I have owned many of the best overdrive/distortion pedals of the '70's, '80's & '90's. This is is by far the most toneful, touch sensitive pedal I've used yet.

This pedal delivers! I have had some of the so called best in the past 35 years, and sold them. Fulltone has done their homework and given us the OCD! Get the 18 vdc power supply and you'll be in touch-tone distortion heaven!

I have been playing 40 years and have owned many many pedals I am so glad I found out about fulltones OCD pedal it just is fun to play again thanks to fulltone .I use it with a G & L guitar with p-90s and a bugera v-22 amp it's just kick *** plain and simple

Primarily a single coil pickup player and needed an overdrive that could give me a broad range of crunch without the annoying HISS that often comes from most overdrive pedals. Well the OCD is that pedal. AMAZING sound! Having the high pass and low pass switch option is also fantastic. When using my Fender Deville amp, which can be bright, I just switch to LP mode. When using my Fender Deluxe III amp, which can be a lot less bright, I just switch to HP mode. The drive level of this pedal is truly amazing also. I can add just that little bit of bite to a more clean rockabilly sound, or go mid drive for some crunchy southern rock/rock sound, or full drive to obtain that full crunch and sustain for heavier rock. Couldn't ask for a more versatile overdrive pedal. Best overdrive I have ever owned!

Giant kudos to Sweatwater and my Sweatwater sales engineer Tim Holsinger. Tim is always on top of things and is quick to makes sure I'm satisfied with each Sweatwater purchase. Couldn't ask for a better company for ALL my musical purchases.

I was looking for an overdrive pedal I could use with my Fender 68 Twin Reverb reissue. I primary use the amp clean, with chorus, echo, reverb, fuzz, etc, but occasionally like a little " crunch " when playing some songs or leads. After reading reviews I decided on the OCD pedal and it works great. I am 100% satisfied !!!!

I'm an intermediate level player and this is the first pedal I own. I've tried many OD/distortion in the past few months. I've purchased and returned 2 because I just couldn't find the sound I wanted. Bought this one without actually trying it in a store but fell in love with it when I finally received it from Sweetwater. I actually contacted Fulltone before purchasing and Michael Fuller said that the OCD was "honest." It maintains the sound of your amp. Great price as well. Thank you Fulltone & Sweetwater!

I received this pedal as a Christmas present and I have to say Santa is awesome. This pedal really opens up my Bugera V22 amp on the clean side. Increases headroom with a smooth sound that does not color my guitar's tone at low gain levels.It is also fun on the drive channel, (although I am generally satisfied with the amount of grit from this channel without pedals). When I add more drive to either the clean or drive channels the harmonics and overdriven tone is glorious. It makes the tubes happy! Although I am still experimenting (lots to tones to explore with the OCD) it sounds great with my Fender Strat, Fender Tele, Gibson SG and Epi ES335. This pedal sounds significantly better than my TubeMonkey OD (although that is a decent pedal too). I love the touch sensitivity of the pedal and the interaction with the volume control on the guitar itself. Very flexible and there are many tones I have yet to to explore. Also anxious to see how it works with my Tech 21 Trademark 60 solid state amp

As always, great service by Jason T. my Sweetwater representative.

Just got Fulltone OCD drive pedal ! Wow my Messa Boogie DC-3 & DC-2 sound even more awesome with this little jewel. A little extra sustain and smoothness. Still sounds like all sweet tubes.

I've been using this pedal for 5 or 6 years. It works well with my set up, and cleans up very well, even with humbuckers. I've found that ceramic magnet pick ups clean up much better that alnico pickups, despite the fact that they are higher output. Still, it works great with my les paul with alnico II PAFs. There is plenty of drive, and the tone knob provides added sparkle. In the LP position, it sounds more like an 80s distortion pedal. I leave mine in the HP position all of the time. It gives a great mid range spike, and provides for a great glassy clean tone when you roll back on your volume. This pedal does everything I could possibly want from an OD or distortion pedal. I can't say enough good things about it. Also, the build quality is solid, and should give no trouble for touring or just playing out around town.

I have had mine for about 5 years now and it has never been rotated off my pedalboard. I also have a King of Tone, J Rockett Archer Icon, Wampler Velvet Fuzz, Catlinbread DLS lll and RAH, Arc Effects Gamut, and a new DOD 250. I use the stuff that works for me, inspires me, and sounds great with different amps and guitars. The Fulltone OCD is just one of those pedals almost everyone would love and it's not even expensive. Excellent build quality and warranty. If I lost mine I would get another one.

for those who doesn't know Fulltone, Well, you should find out. This for me is the best sounding overdrive

After using a wide range of overdrive and distortion effects over a number of years with generally underwhelming results, this one finally provided a sound and feel that works with my playing style. I can set the volume for unity gain, the tone neutral, and the drive knob at saturation (about 2 o'clock) and control the amount of distortion with my guitar's volume knob, from almost clean to sizzling hot. It behaves like a good tube amp's front end, just like an overdrive pedal should, and there's no coloration or alteration of your guitar's natural sound in the LP switch position. Bonus points for the 9V external power jack and a case design that allows the battery to be replaced without removing the pedal's base from your board if you prefer to power it that way. Great pedal.

This is without a doubt the best overdrive pedal I've ever owned. I've been playing for 12 years and do a lot of live shows so I know how tone and cutting through a mix can be a problem for some guitar players. This pedal will go from clean boost to hard rock easy. For those wanting this as a one pedal fix all, don't hesitate. There is PLENTY of gain with this thing. Can easily play anything from Zeppelin or The Stones to Metallica or Three days grace with the turn of the gain knob. Unlike most drive that get then as the distortion goes up, this pedal actually gets thicker. It makes chucking power chords sound amazing. And the tone... Where do I start? Even at the higher distortion levels you can hear every string. I watched every YouTube video I could find on this thing before I bought it and none of them do it justice. So stop thinking about it and reading reviews! Go buy it and thank me later!

Amazing tone for a pedal, very dynamic in it's range. worth every penny.

I finally found a dirt pedal that has what I have been looking for. Great variety of tones to be had here. Works great on bass and guitar (have yet to try on keys or drum machines). I have used it in front of a Fender Twin Reverb Custom 15 with a Jazzmaster as well as an old Eden David VT-.40 head with 410XLT cab with a Jazz Bass and also an old Traynor YBA-1 going thru an Avatar 2x12 cab with an Epiphone SG (this combo produced a nice creamy fuzz, works great placed before an EHX BIg Muff). I can finally say that my dirt pedal search is over.

Great pedal! Does what it's supposed to do do, and does it well. Sounds best at 18v.

Before this pedal I had a Boss SD-1 made in Japan from the 80's. It has the 4558 chip and is quite a decent distortion pedal. After hearing the OCD pedal I had to have one. No regrets it's a great pedal and gives a lot of options. Well worth the money!

Just the right amount of ingredients here

This pedal does it all and more. It's really hard to hold back. I wish I would have bought this one a long time ago. Where's the beef? Right there in that little pedal! It kills it!
Thank you Sweetwater for the great deals and great service.

I've never been able to find an overdrive pedal that makes me happy. Tubescreamer, Blues Driver, etc. I've purchased the big names and they've been on my pedalboard in a live setting at one time or another since 1979. So, there's my attempt at street cred. Let's get to this pedal. The secret to the ODD is that it's an Overdrive/Distortion pedal. Want crunch? It's there. Want distortion? It's there. A distortion pedal can be too much and an overdrive pedal can often not be enough. If you're looking to get that blues "edge", that rock "sting", that outlaw country "bite", and/or that singing classic rock "creamy" sound, you're going to love this versatile, touch sensitive, volume control roll off clean pedal. I hesitated because I'd been disappointed so many times, but this is easily the best pedal I've had for Overdrive/Distortion. It's irreplaceable on my pedalboard.

I bought the OCD Pedal to used with my Fender Blues Jr. III and I have not been disappointed. From moderate tone to all out crunch this thing is amazing. I would recommend to a friend.

The moment I plugged this pedal in and turned it on it roared through my amp. I played a standard strat through it into a Fender Blues Deluxe. This pedal is amazing and is great for a higher gain blues tone. Not so sure on how I made it through the past couple years without this on my board. Hope this helped!

I am very happy with my choice to purchase my new Emperor II Pro. I won't be comparing this instrument with any other archtop guitar on the market, other than to say, the craftsmanship is excellent, and my Gibson ES175 comes in a close second. I have never owned an archtop guitar with such a wide range of voices. I play Jazz and Bossa thru my restored Boogie MKIII, clean. The bass is unreal and sounds deeper than I have heard in any guitar. If you get a chance to play a 'Pro' you will see what I mean, and yes, I would recommend this instrument to a friend. Mike Soper is my sales engineer and I want to take this opportunity to thank Mike for his care of my guitar needs over the past years.

Got this right after my blues deluxe re-issue. Thought I might need some more drive for a few songs.
Wow this combination is incredible. use is with the clean channel and tweak the amp tones what a sound.
You don't lose any of the base or mid tones as with a lot of pedals. I was tore between the Suhr Riot and this one. I had played through the Riot and wow. But this I like better at half the price!
I also hooked it up through my blues jr tweed. had to tweak the settings on the amp different from the BD.
but I finally got the tone I was looking for. I would have to assume this pedal would compliment any quality
tube amp but can't say for sure as I only have the two listed above.
The only think I don't like it is too loud. the volume at low is too much. Would like more adjustability
on that.
Basically the best distortion overdrive pedal I have owned, I have had a boat load of them.
Get one trust me. And of course get it from Sweetwater! They definitely know their stuff.

I'll admit it. I bought this pedal because I saw it on so many other players pedal boards. I came to realize that players dig it because it DELIVERS! I also have a Suhr Riot to compare it to, which cost me about $70 more. The Suhr has a lot more "drive" but the OCD seems to be "more defined" on most things. I've pretty much stopped using the Riot and almost always turn to the OCD. This was after I thought the Riot was the total stuff!!! The OCD works very nicely on the clean or slightly dirty channels of an amp (I'm thinking of the Marshall JVM I use). The Riot (I believe) was designed to be used on mostly clean channels. There, it DOES deliver! However, the OCD is a better all-around distortion pedal- at least in my experience.

I recently purchased a vintage strat and I was looking for a new overdrive pedal to complement it. My other guitar is a custom les paul with slash pickups. I was running a mesa boogie throttlebox through a fender 68 custom deluxe reverb, and the sound is to die for, but it doesn't like when you turn the gain lower than 11 o'clock. This pedal sounds amazing from 11 o'clock down to zero in the lp setting, and it is exactly what I was after. When you crank it it sounds good too, but nothing like my mesa throttlebox. I also have a mesa boogie rectoverb 25 combo, so my standards are pretty high. I wouldn't recommend this pedal for someone wanting a ton of drive, this is more for a clean boost to mild overdrive in my opinion, and it does that without flaw. You can set it to do anything from nothing, to raising the volume, changing the eq, to light or full overdrive. Amazing pedal. Buy it.

Glad I picked this one.

This is definately one of the best overdrive pedals I've had.
If you want just a little boost, full blown overdrive, or just
want a great sounding distortion pedal, this is the one.
I was going to use 2 of them, but found one is enough.

The Fulltoe OCD is just awesome. I like the HP and LP switch which can be used to taste but the LP sounds better with my Fender Jaguar and Mustang. I have a Fender Blues jr amp which is a nice tube amp but the OCD make it great. I purchase this the OCD pedal on the advice Ryan Schmidt my sales engineer and he was correct. The OCD gives a great boost and just makes the sound fuller no pun intended.

I'm a guy that has played semi professionally for quite a while over the years. Mainly weekend warrior stuff having to mimic tones in cover bands. I own/or owned many tube amps,rack gear and guitars. This OCD pedal really feels great no matter what guitar or amp is used and performs wonderful in front of a tube amp. It is touch sensitive, performs very well to guitar volume inputs and drips tone. Based on two other reviews on this site, I called back after receiving the pedal and bought an 18 volt power supply. Oh my does this open up this pedal. I felt the change was mammoth, going from a really nice unit to exceptional. Headroom was increased and in the HP setting it sounds a bit more British to me. This is one of the best pedals I've owned. Buy one with the 18 volt power supply and I bet you will love it. (side note the manual included with the pedal outlines you can use the 18 volt power supply). As usual Sweetwater did a great job getting the pedal out to me lightning fast. I bought a Wampler Plexi Drive Deluxe and ended up sending it back due to this OCD sounding so good to me. The Plexi Drive was a great pedal and I'm not saying anything against it. To me this OCD gave me the tone I was looking for with a huge bottom end.

There's nothing flashy about this pedal. It just simply works, and is quite versatile. I have a variety of boutique pedals, and I've tried several times to replace the OCD with something else, only to realize that it's too good to let go of. Low gain, high gain, whatever you have in mind... chances are it will do the job very well and without fuss. Has a very large sweet spot and is very tweakable for a 3-knob pedal.

I am 68 and am still leading my own band doing my original tunes....In the 70's I was in the UK...playing a 60's ... Marshall Stack........the OCD can clone that amp!!!
...listen to early Hendrix when his pedals are off or Clapton on Sunshine of Your Love....that's what the OCD
does best...a massive sound with huge bottom end with just the right mids and highs to give you a great definition on the notes and chords...and no mud....a sound aggressive and huge but you can still sing over.
...it is versatile enough to squeeze other sounds out of it...but your much better off to set it up to do the Marshall Stack thing and pick up a cheap overdrive or distortion unit to layer over for leads etc.

The OCD from a tone/timbre standpoint, is the closest thing to the front end of a classic VOX tube amp I have ever experienced. I bought this device to bring the ability to control the overall volume and drive-distortion to my pedal board, regardless of the amp or PA system I am plugged into. This is incredibly freeing when playing in various places with various amp systems but still allowing me to keep my pedal setup consistent.

There are so many effects pedals on the market that it was hard to decide which one to buy. I spent a lot of time reading reviews before finally deciding on this one. I am very pleased with the OCD - it does everything they say it will do. It's a huge boost, has great distortion, the tone control is a big help, it's built very sturdy, and it looks good too. Don Carr's Video Demo is a very accurate and helpful review of this pedal so make sure you check it out. A good bang-for-the-buck pedal.

As always, Sweetwater had my order packaged & shipped same day. Thanks again for the great service!

I was looking for a good overdrive pedal to cover the sounds I was searching for. This pedal is very versatile and it did the job. Great lead tones for my Gilmourish tunes. Luke Herian, as always you are awesome! Been shopping with you guys for last 7 months or so and you always give me a call to let me know my gear is coming. Great job!!

I've had this pedal for three years now, and it works the same as it did on day one. Originally bought to make up for tone in my solid state amp, now I run it through my Fender Blues Deluxe and it sings. We were just in the studio and our lead guitar player AND bass player used it on several takes over other pedals like the RAT (which I still think is pretty cool) and the Wampler Triple Wreck Distortion pedal (twice the cost). I bought a blues driver and returned it after a month because it felt just redundant next to this thing. It breathes life into your tone. Doesn't offer the gain of some pedals or amps, but it cuts through better than anything I've used. I can get a nice Duane Allman slide tone with it or some Led Zeppelin-esque overdrive. Will also suit your 90's rock needs. My number one pedal. Couldn't ever see parting with it. Also kicks the crap out of a well-known green OD pedal...

I also recommend the Danelectro DA-4 9-Volt power supply which you can use to starve it of some power, and get even cooler tones.

really great tone

Good in sound fat sound i use it in a clean setting for blues rock sound

Great range across all adjustments, especially drive knob which takes you a little beyond overdrive into nice distortion for my purposes; I was looking for something that covers both . . . no need to supplement this with another distortion pedal. I appreciate Don Carr's review on the Sweetwater website, as everything he demo'd came through when applied to my set-up. Side note: small size is nice! Made me wonder why so many other pedals take up so much space. Very feature-filled pedal for the money.

Sparkles! Gotta agree with all the good reviews. Thought it was fabulous then I got a voltage doubling cable to run at 18 volts. It's off the charts! If you can run it at 18, by all means do, but it totally rocks right out of the box.

The Fulltone OCD pedal is by far one of the best preamp/boost/overdrive pedals I use. I find that if you use it in line with another drive pedal you can and will achieve The Eric Johnson dirty sound with ease! I place it before my BK Butler Tube Driver and you can dial in boost to thick rich overdrive that sustains for days! This is one of my very favorite pedals for that singing drive sound. Works great for thickening single coil pickup's. plays well with other pedals and amps. I have owned this pedal for years now and never had a single problem with it. tough as a Tank! If I lost this pedal I would not hesitate to buy another one ASAP.

Like it so much I bought one for my brother just so I have it when I am at his house. Great tone does not get crazy dirty like a metal zone but has a clear presence and growl...

Best OD pedal I've used. Very versatile. Great crunch. Cleans up very nicely using your guitars volume knob. It does this so well, I now use it for my clean sound. As always, Sweetwater is the best! Thanks Scott!

I have tried many, many, many different OD pedals. Some I have liked very much and used often. This one is the best I have ever tried. So good with my Strats. Doesn't really change your basic tone, just enhances it. It sounds good with all of my different amps and guitars. It will now be a permanent part of my setup. Best $100(ish) you can spend. GET ONE.
As always great service from Sweetwater and rep Greg Savino.

OCD is the best dirt box I've ever had. I run it at 18 volts right after a fulltone fulldrive 2 also at 18 volts. They stack well together. I've tried this setup with a mesa mark v, fender blues deluxe, Marshall, peavey valveking. Using a strat, les paul, prs, and it works great with all of the above. I haven't found another dirt pedal, or od/dirt pedal combo that is this universal until now. And Aeric Brenner is the go-to-guy at sweetwater for excellent advice and courteous service.

If you're looking at this pedal and reading reviews then do yourself a favor and pick it up. This is the most transparent overdrive I've seen yet. I like to run this with my amps as a boost and will occassionaly add a little drive as well (depending on the amp). Excellent pedal. Also, I think the price has dropped since I bought mine!

This overdrive is awesome. Bought this recently along with a new 65'Deluxe Reverb Reissue. Got here in a couple of days, almost a week later I'm just blown away. I had read the reviews many many times and like most effects and sales hoopla I expected the usual below expectations results. Well I'm definitely sold on Fulltone and most certainly the OCD. I been playing my Eric Johnson maple Stratocaster through it all week and I am certainly pleased with how transparent this thing is. All I hear is a good overdriven amp and nice thick rich tone that doesn't get brittle and thin. It doesn't scream pedal to everybody listening. Single notes or chords everything comes through nicely. I've got this on my pedalboard behind a BK Butler Tube Driver and in front of an old 80's Boss DD3 (Made in Japan) and it plays very nice with both. I have also had my TC stereo chorus behind it as well with good results. Love how well built this pedal is. Its built like a brick. I'm sold on Fulltone quality. OCD is a steal at the current price.

The Fulltone overdrive is very versatile. You can go from mild crunch for rythem to a full blown fuzz for lead. I use it in combination with a Rat-2 distortion pedal. When I blend them together, with a TC electronics Flash
Back delay, I can get a pretty convincing. David Gilmour tone. I would recommend this pedal for anyone.

I have been using the OCD as my main distortion sound since I got it a few weeks ago.Tonight i tried it as a clean boost and was floored by the rich tone.Great pedal with a variety of sounds and built like a tank(this pedal is SOLID).Good job!

This is the only dirt pedal I have. Sounds awesome with every amp and guitar combination I've tried. Just buy one.

This was exactly what I was looking for; some extra punch and crunch while still maintaining great tone. Well built and no extra noise when not in use. Simple, straightforward controls. Combine that with the great Sweetwater customer service and support and you can't go wrong. I will definitely consider Fulltone pedals for future purchases and will always make Sweetwater my first call for sound equipment.

The OCD is the perfect pedal for anyone looking to add just a little bit of crunch to your tone. I never go to a gig without it. What I like most about this pedal is that it adds just the right amount of overdrive given how much signal you put through it and how hard you are playing, allowing you to adjust from clean to crunch with both your technique and your guitar's volume knob. It adapts to you! I would not recommend it as your one and only lead pedal, but for anyone looking to add a little bite or get a good blues lead sound this pedal is absolutely magnificent! I am very happy with the OCD.

Sweet, crunchy gain without sounding trashy. The tonal options cover quite a bit of ground, and the gain is usable through the entire range of the knob. Excellent as a standalone overdrive or distortion and for boosting a crunchy amp.

I typically go out and play a blues based style some crunchy some more mellow on the soulful side. I bought a Fender Deville amp but the thing is too good really a stage amp. I needed a sound that wouldn't peel the paint off the joints I play so I thought get another TubeScresmer. But in investigating what is out there I went with the Fulltone OCD. Get one it will do the job.

This really kicks! I like the sound and drive it gives to leads.

The OCD is incredible!! The versatility and the transparent nature of the OCD are unparalleled. The drive switch enables you to switch from a beautiful clear overdrive to an incredible distortion/overdrive sound which still maintains your guitar tone. You can play Blues, Rock, Jazz, Hard Rock, Country and beyond with this pedal. The power that you get from the OCD even on 9v is amazing it will drive your tubes to the max. The OCD also can handle 12v and 18v as stated in the owner's manual. I am currently using an 18v adapter and it increases the headroom and the overall tone of your sound. I didn't think the OCD could sound any better, but with the 18v it does. Incredible pedal, a must have for any TONE CHASER!!!!

OCD pedal does what it says. Maybe not for metal-heads but for blues & rock is right on. No generic mush, guitars keep their integrity. Great harmonic content without excessive saturation.

Exactly what I was hoping for. Contacted Sweetwater and said,"I'm playin' single coils thru a Princeton Re-verb...no gain channel and I'd like to crunch it up just a little, whaddya got?" Mark responded within a half hour and suggested the OCD. Perfect match and just the effect I was looking for. Have since added the Dunlop 18v power and I am set. Would definitely recommend the pedal for low-mid boost needs. Woulda given it a 5 if it came with any kinda power supply other than a battery.

Unbelievable overdrive. The range and types of sounds it produces in front of a tube amp is the best I've ever heard. Very fair price on a terrific pedal.

This is the best overdrive pedal I have ever tried or owned. I would highly suggest one for guitarists of any style.

On a whole different level than other OD pedals - when I first saw the "OCD" in the title it made me think "oh this is just another nasty OD for Metal Heads and Shredders - Not SO!!! I play POP and Blues and needed an OD that had rich, full tone when cording but also would not smear when I kick on my "Blues Driver" for lead - the ODC by Fulltone delivers on every front - but there is a catch! buy the 18V Adapter!!! I put it in my floor board with the standard 9V connection and thought it sounded just OK, perhaps a little thin, so I took it out and threw it in the heap with all the other shredder pedals. Then I remembered the YouTube video I saw where they said - "You really ought to hear this with the 18V adapter..." So, I grabbed it out of the heap, bought the 18V adapter and marched off to practice. I plugged it in - applied the 18V's and Holy SH**!!! no I mean truly - a world of difference! Best OverDriver Out There!!! bar none!

What a great pedal! It doesn't just make you sound better…it will make you play bettter.
It's super reponsive to differences in picking. Very versitile. I can't believe the wide range of tones you can get out of three knobs and a switch. Get one now!

I purchased this to play a gibson 335 through a deluxe reverb reissue with some clean to semi dirty blues tones. Also with the bridge pickup and some delay I can get a Brian Setzer type if tone. The pedal sounds great. It can function as both a volume boost, or a gain boost and maintains the picking dynamics so you can get cleaner tones when picking lightly and more distortion when picking hard.

I am giving this one only 4 stars simply because I have limited experience with distortion pedals and thus cannot accurately compare to others. I will say it is a good pedal. and solidly built...check out some youtube reviews for more info.

Really excellent tone out of this pedal. Worthy of its reputation.

My wife got me one of these for Christmas. I use it in front of a Tweaker head. It really adds to my tone and with the gain all the way down acts as a boost while providing some grit if you attack the strings harder. I used to use a old Ibanez Tube king tk999us and this OCD blows it away for warmth. With the gain at 12:00 on this and the Tweaker with master about 9:00 it gives me an awesome Crunch at a livable volume.

I just picked this guy up a few days ago and was blown away when i plugged it into my fender amp and Gibson guitar. The tone and drive are amazingly smooth while maintaining the crunch of a real tube amp. I got the chance to play through a vintage overdriven Marshall next to this sucker and it sounded almost exactly the same, just as Fulltone says!! It also has pretty good battery life (20 hours) but i would suggest getting a power supply (Pyle Pro, Daisy Chain, Voodoo lab, etc...)You really can't go wrong with this pedal but I suggest trying it out at your favorite local music store before buying just to see if it will suit your needs

Great Quality Pedal especially in 18V!!
Thanks Sweetwater!!

This is a fantastic pedal. A great price at $135.00 It brings your guitar to life, and will help to take the mud out of your other pedals too.The boost can be subtle or aggressive. It's great all by itself, giving you tons of options. I own several types of guitars which include Strats, LP's, Tele's with an array of different pick-up configurations. This box WILL find the sweet spot for all of them. I usually go full bore with pedals of this nature, but with the OCD I am in awe of the subtle nuance it creates at lower settings. I'm sorry it has taken this long for me to find out about this magic box! But I've got it now and I'm gonna keep it .
Thanks To Mike Hammond for the great support .

This pedal performs as advertised by the manufacturer. I like the smooth, brown, british power tube distortion sounds, as opposed to gainy buzz. The OCD gets me where I need to be at more reasonable volumes, while preserving a lot of the touch sensitivity you would expect from a wide open non-MV amplifier.

While I admire the boutique stuff, I can't really afford/justify spending more than $100 for a single pedal in most cases. But the OCD is reasonably priced, and EXTREMELY versatile. The first time I plugged it in, I felt like it took my small VOX combo amp to a level of quality I hadn't gotten out of a pedal before.

While you're not going to play thrash metal with it, there's enough gain and tone ranges here for this to become a primary overdrive on your pedalboard. It does a great classic rock tone (seriously, Jimmy Page started coming out of my amplifier), and can also be used to push other distortion pedals. It's one of the few overdrives that works well both for lower-tone rhythms and higher-pitched soloing. The HP/LP switch also gives you the choice between a louder (and brighter) tone, versus a more muffled one. That's a great thing to have for dialing it into your specific amplifier. The OCD is an instant classic and almost universally beloved.

My awesome girlfriend got this for me for my birthday! I was expecting it to be an awesome pedal. But "awesome" doesn't even come close to describing this thing. In fact, it blows "awesome" out of the water. I played 3 different guitars through it and all of them sounded incredible, yet each sounded the way they should... different! Some distortion/OD pedals make all guitars sound the same. Not this one! Has an incredible sweep on the "Tone" knob, and the "Drive" control allows you to back off to beautiful crisp clear tones, turn it up a bit to buttery, or crank it up into madness! Monster tone! I can't imagine anyone not liking this pedal. Best OD out there! And it responds to your attack on the guitar.... Incredible, awesome, killer, fabulous, fantastic..... one word can't sum it up. If you are even thinking about an OD pedal, this IS the one you want! By far the best pedal I have EVER owned. I am sold on Fulltone! Can't wait to add a few more to my rig. And a 5 year warranty? It's built like a tank!

I have heard a RAVE of reviews about this for years, eventually I bought one. I was disappointed at first as it seems that all it could do was harsh, high end screaming. It just didn't fit the role I was hoping it to fill.

BUT, I then started tweaking the knobs, and my jaw just dropped. This thing DRIPS with tone, and by far the best over-tones and harmonics on an overdrive pedal. It just fattens up my Strat tone while being totally transparent!

AND, this is also by far the most dynamically responsive overdrive I have tried. It responds to your picking dynamics so well, just like an overdriven amp. It is also responsive to your volume knob. Turn it down to 7-8 and it is just so SWEET!

This thing is an all-round BEAST. And for $140, it is the bargain of the guitar world. I just got the CMATmods Signa Drive (very good TS-clone), and the OCD still wins out on tone.

Best overdrive out there, you won't regret it.

I was looking for something to give me just a little breakup, and at the recommendation of a friend, the OCD was it. But I actually use this one for my mid level overdrive now, and use my Keeley mod Sparkle Drive for the lighter overdrive. Used it for the first time during CMA Music Fest and love it!! Definitely a mainstay on my pedalboard now!

The Fulltone OCD is a really sweet overdrive that reallly compliments any tube amp I've used. It delivers that cutting punch you want in relation to your picking attack and after trying several different overdrives over the years this one is the one that will stay in my pedal board.

Super transparent and respond just like a tube amp to your picking dynamics. It's like adding another channel to your amp. I use it to add a little dirt to my clean and to boost the drive channel on my blackstar and this thing sounds incredible. It doesn't color your sound at all, just enhances it.

Great blues -rock overdrive!,built solid,true bypass,hand made in California,the only reason I didn't give it 5 stars is because nothing is perfect.I have used it at 2gigs so far no problem,I play blues and blues rock,it's perfect for that seven tone,great pedal,great service,I have been a sweetwater customer for awhile now,and the service is great everyone is very knowledgeable!,I don't go anywhere else

I'm going to play devil's advocate here just for the sake of anyone who wants a slightly alternate perspective on the OCD. Let me first say that it's a great pedal for all the reasons other people have listed, but some of the things this pedal has been praised for have actually been drawbacks in my experience. My advice is to beware the "not coloring your tone" aspect of the OCD. If you find yourself favoring American voiced, compressed, or midrange-present overdrives, this may actually not be the answer to your overdrive prayers. This is a huge and saturated overdrive, as many have mentioned, like a marshall half stack, but depending on the guitar, amp, or EQ settings you use, the tone of the OCD can be very hard to use. For instance, the openness of the single coils on my Strat is something that I absolutely love when I'm playing clean. The tone is thick with bass and has a great bell tone chime in the treble. The problem is that the OCD preserves the openness while saturating it with overdrive, and the result is bass undercurrent that is wobbly and out of control and a treble that is far too biting and harsh. So unless I'm very careful about my amp and guitar settings before turning on the OCD, I end up with a tone that's pretty unusable. I think another thing worth mentioning is that this doesn't compress like a lot of other drive pedals until you turn up the drive knob pretty high, so the "fatness" that is often a side effect of compression isn't as present. My point in saying this isn't to bash the OCD because it truly is a well-built, reasonably priced, musical, and versatile overdrive. I also would imagine that the problems I'm pointing out are more prevalent with single coil guitars than those with humbuckers. Still, I think it's worth it to ask yourself whether or not you truly want your guitar's tone replicated in an overdrive. You might actually want your drive pedals to "color" the tone in certain ways.

The OCD has replaced my TS808. More transparent than the Tube Screamer

I think it's normal to be slightly disappointed after purchasing something with this much hype surrounding it, but like so many others, this pedal has won me over.

I was looking for a drive pedal that would contrast my TS9. The OCD definitely does that, and so much more. It's not nearly as mid-heavy, nor does it color the sound as much as the TS. The subtleties of my strat stay in tact, without substantially cutting or boosting the spectrum. It also reacts pretty much the same way as a tube amp to softer dynamics and rolling back the volume knob. I love the classic sound of my Ibanez, but it seems that the OCD can do pretty much everything else. You can get incredibly specific with this pedal, from clean boost to huge overdrive, and most every sound in between sounds great.

There's also a lot to be said for how well this pedal can drive a tube amp at low volume. This is useful not only for practicing, but for any gig where your amp can't be too loud, but you don't want it to sound wimpy (in my case, mostly church services). If your miking the cab at low volumes and being mixed into a system, this functions as a boost just fine.

I can't speak for how well this pedal works with solid state amps, but through my Fender it really sounds fantastic. If you're a metal player, this is probably not the pedal for you, but I'd highly recommend for just about every other genre. This is really a useful, well-made piece of equipment at a moderate price.

This pedal is wonderful. So many usable tones are available, and it's very easy to dial in.

This is the fourth version, and functions a little differently than the other three older versions. If you're interested, check out demos of the others. I personally chose the third version. It seems to have a little more gain than the fourth. Excellent for cleaning up a clean tone or sending your solos over the edge. I'm not a huge fan of the other other fulltone pedals, but I'm 100% happy with this one. And the price is great for this kind of quality.

True Bypass. None of that high pitched "transistor radio" drive. Make a "tweed" sound like a "plexi". Make a "plexi" sound like "heaven". Turn the drive way down and it's a great boost. DOES NOT change the true sound of your rig. It's like adding a channel to ever channel your amp has. This is what you want!!!!! HP & LP is nice too, make that two channels for ever channel your amp has.....

This pedal sounds really good especially if you match it with a tube amp. The overdrive is very transparent. It produces a very nice sound and response well if you adjust the settings. worth buying!

Many people are critical of the "Fulltone hype machine." However this pedal truly lives up to all of the praise it's received.

I've played this pedal through my Vox AC-15CC and it is a complete monster. If you roll the drive back all the way and crank the volume pot, it serves as a great clean boost. With the volume about 12 o'clock and the drive at 3, flip the toggle to HP and you can get amazing british crunch. I'm still learning what this pedal can do and am consistently amazed at the amount of different overdriven sounds that I can get out of it.

If you are looking for a distortion pedal that will serve you well for Death, Grind, thrash, etc then I would recommend looking elsewhere. But if you are looking for more of that NWOBHM sound (which I was when I bought this) don't hesitate and buy this.

I have V1, and V3. I use the V1 for lighter OD with the LP mode. Fantasic light boost tone. V3 is set for more gain/mids and in HP mode. This version is close to V4(current), and I can't live with out this one. I can take this OCD and my Eric Johnson strat and be very happy.

Good things about the OCD...

VERY amp like in "feel". Works great with an amp thats breaking up some.

HP/LP mode give some very cool sounds with the HP the tighter, with more gain. LP is looser IMHO.

Not really much $ for the tone!!!!

The tone is basicly "MORE" of my amps great natural tone. No real big mid hump.

NOT a TS clone in any way.

Responds to the Volume of the guitar like a great tube amp.

Can be run up to 18v for even more tones.

Rock solid night after night on stage!!!!!!!

Works great with Humbuckers and Single Coils. Took a few tweaks with my p90 Les Paul Jr.

This pedal actually replaced my Kelley TS-808. Yes, it's that good! I highly recommend this pedal.

This pedal is outstanding. It does NOT give you a heavy metal pound, but for heavy rhythms and REALLY beefy power chords this pedal kicks ***. as far as soloing goes and single string voicing it is not as effective. If you are looking for a ripping solo you should stick true to the amps distortion for sure. The thing that I simply admire in the OCD is that they took out the EQ equation and leave you with your "True" tone only its now punching you in the face. Killer pedal. Every rock band needs one.

I play Rock and Metal, some neo-C leads. I've tried so many different types of overdrives and was never satisfied. I stuck it out with the ts-808 for a long time.
The OCD is not your average 808 clone.
It has its own sound, and boy is that sound sweet.
it sounds more like your amp giving you the gain than a pedal.
You get the cool o.d. harmonics with the gain knob barley on. nice clean overtones.

I've played with all 4 versions.
for me I rank them in this order:
v1-v4-v3-v2
I like the v1 the best because the mids are scooped a little compared to the others.

Lately I've been using it with a Fulltone Soul Bender fuzz. Heaven!

I will always be searching for something better but i don't think I will ever sell it.

(*Listen to Paul Gilbert(uses one)
and listen to Takayoshi Omhura - in a rough state.
