this thing is absolutely amazing if you're using MIDI, i've noticed other reviews complaining about the interface understandably but you must realize this device is primarily intended to be used with MIDI and the onboard interface is just there in a pinch and it's not intended to be used on stage. if you want physical sliders and program ability then get the Boss 200, the Source Audio EQ2 is purposely designed to be space saving and controlled via MIDI and is why it is marketed as a programmable equalizer. it is meant for the guy or girl that wants to set up patches and click a switch on a foot controller. If you don't care about program ability and you just want an awesome equalizer get the Empress Para EQ and it's roughly the same size as the Source Audio EQ2. overall if you use this device as intended it's great and works as advertised without issue but if you're looking to use it in the same way you would use a normal equalizer with knobs this isn't your guy.

I've had so many pedals over the last 40 years I can't possibly remember them all. I was fortunate enough to spend every day surrounded with high end gear. I was taught by a few very generous engineers with some sweet platinums under their belt how all of this stuff works. Then I bought it all, lol. I'm just a guitar player, but I do not like having to rely on others to track and mix everything I do. I needed some knowledge of how this process worked. From thinking up an idea to selling it and getting paid. Enough about that. Putting an EQ in between my guitar and my amp was a big nope. I was use to mic pre's and compression being at the console. The more you start putting between guitars and amps, the thinner it started to sound. Not necessarily true. I just got hooked on a certain organic tone and didn't like changing it. This EQ works sounds amazing in a board. I'm moving it around a little bit so it's the last thing before the amp. It's also works on the sends and return of both amps. Signal chains are finicky and you have to find your spot. Once dialing to what you like you'll always want it on.
Don't hesitate to grab one of these.

This is a fabulous piece of gear. The Neuro software makes programming super fast, flexible and easy.

You can either run it stereo, mono or...

I have two live acoustic guitars with very differnt eq curves. I run one into input 1 and the other into input 2. I use Output 1 mono to the pa. Since the two input channels can have seperate eq curves I programmed the footswitch to switch between the two inputs, each with their own guitar/eq curve/output levels. All in one tidy super flexible box.

I play Gypsy Swing on an acoustic archtop and I'm running this in the effects loop of my Tonedexter preamp. I was looking for a more 'surgical' EQ to eliminate some of the extra noise/sympathetic ringing. I also use the high pass filter to leave a little more room for the upright bass, roll of the treble a bit, and bring the mids slightly down. Being able to really get in there with the software (as if I'm EQ'ing in my DAW) is incredible. It really tames and improve my sound. It's so awesome that it has two independent channels as I am also running my rhythm player thru channel two. Very pleased! In the pics... archtop in red, tenor guitar in blue.

I am using this pedal in the FX loop of a Dual Rectifier. I've tried a few digital EQ pedals and this is easily the best one. It's super quiet, easy to use, and has some great features. While you can edit the settings on the pedal itself, I prefer to use the computer based editor as it is so much easier and faster. For my purposes, this is more of a "set it and forget it" pedal vs ones that have the sliders on the surface of the pedal. Regardless, it took me probably 5-10 mins to get a good sound on the Dual Rec.

I would recommend this EQ pedal to anyone that doesn't need to constantly edit or make adjustments on the fly.

I'm currently using this as an EQ, volume pedal w/midi expression, ABY, and wah pedal w/midi expression. If you have a midi controller you can really get this thing to do alot for you. I gave it 4 stars instead of 5 because it glitches sometimes when simultaneously configuring my custom wah settings and rocking the expression pedal for real time feedback. It might just be too much processing to handle at once, but in any case, this thing is pretty convenient and versatile.

The Source Audio EQ2 is a completely fantastic stereo EQ. It sounds wonderful and can do some very surgical EQing. I bought three of them. I had a live techno set consisting of Roland TR-8, Roland TB-3, and Novation Circuit. The Circuit & TR-8 were giving me digital hums and I used this to nearly completely take out the offending frequencies. The software editor is quite good for creating and saving presets and is very intuitive, giving graphical control of the EQ and options for all other features. On the TB-3 I wanted to flip the phase and also do some enhancement EQ (no surgery this time). In all three tasks the EQ2 performed superbly and was completely easy to use. I'd recommend the EQ2 to literally anyone needing a stereo EQ for ANY instrument either live or in the studio. It takes a standard pedal power supply that it comes with.

I use this pedal for acoustic guitar. I have several guitars that I alternate between, often at gigs with no access to the mixer and running from a saved preset.

This pedal allows me to dial in a preset for every guitar that normalizes them all to the same level, eliminate feedback and problematic midrange frequencies, and delivers the best tone possible from each instrument with minimal fuss at the gig.

The pedal is easy to edit, and will keep your changes even while switching between presets. At the end of the gig, you can either save your changes or let the pedal revert back to the original saved setting when disconnected from power.

The Neuro app is very user friendly, the tuner is also fantastic, build quality is solid. This pedal has loads of features, but none of them feel gimmicky. They are all incredibly useful and flexible. I cannot recommend this pedal enough to anyone who wants to take the time to sculpt their sound!

The power and flexibility of this unit brings studio power EQ and routing to your pedalboard. As a bass player, I use this on the front end behind the compressor in channel 1, out to my PSA 2.0 and back into channel 2. By doing so I am able to emulate EQ curves from popular amps like Ampeg, Eden, Mesa, Trace Elliot, etc. on channel 2, simulating the various EQ switches onboard those amps. Noise reduction is fantastic when using higher gain for fuzzy or gritty sounds. Mine is paired with the Soleman midi foot controller which gives me access to 128 memory locations. I have about 25 patches that cover just about every genre out there from 50'-60's round tones to aggressive prog and djent both clean and distorted.

The Neuro editing software is very intuitive and makes Editing/Saving/Loading a snap. The EQ curves are drawn onscreen for each band which is a full 10 band parametric per channel, or first and last frequencies can be set as shelf or bell. High pass filter is also available per channel. Channels can be run parallel (my setup) or cascaded in series to give you a full 20 bands.

This pedal is an absolute MUST for anyone wanting incredible control over their tone. I highly recommend to anyone, especially if you are struggling to dial in that perfect sound.

This is the eq and more I've been looking for all my nylon string guitar. To have adjustable high pass filter and low pass. Then also an added bonus is the noise gate. Now the eq. To be able to adjust the frequency, q, and level any way you need is just such a blessing and great tool. I use the pedal with my Yamaha SLG200NW and it really tames the lows, mid lows to what I need so I can tell the FOH just keep me flat and all will be good. I also use it on two other nylon string guitars with LR Baggs Lyric, and Dual Source pickup systems. Pre/ Save storage work great. I run from the wireless in mono and out from eq to stereo. The editing software rocks from Source Audio (I've only used it on a mac Intel Mac Book Pro) Source Audio and Sweetwater are just amazing companies to work with. Thanks Chris M and Sweetwater staff for getting the pedal in great shape and quick.

The EQ2 is compact, versatile, super-powerful, and reliable.

The EQ2 helps me find my perfect tone, adjust for volume/tone differences between my pickups, and solve problems. For bass, I can make narrow notches at precise frequencies to compensate for room resonances-- without compromising the low end. I can create all kinds of sonic "personalities" with ease.

It functions in true stereo, or as two separate EQ's, even in different positions in my signal path. For example, I can use it for both pre-drive boost/EQ and post-drive EQ! The EQ2 has solid MIDI implementation, and provides effective options for realtime control.

The on-board user interface felt a little awkward at first, but works fine for making quick settings and storing a few patches. From the first screen, it adjusts like a graphic EQ, but it's easy to access most other settings from the unit, including coarse adjustment of parameters.

The Neuro Editor software allows me access to many more presets and more config settings. It gives a graphical view of the EQ curve, and provides much higher resolution control of parameter values. With the mobile app, I can connect the headphone out of my Android or iOS device to the EQ2, and the app sends out bursts of "coded audio" to change settings in the unit. Works well.

A firmware update in 2021 added a low-pass mode for the 10th band, in addition to Peak and Shelf modes. For the input high-pass filter, they increased the range from 80Hz up to 250Hz which makes it more effective for things like cab simulation.

The EQ2 is an absolute beast, and with all the added features (gate, limiter, tuner, wah, clean boost) the value is off the charts!

I had high hopes for this pedal but after I started trying to use it, I discovered I just hate the SA editor thing and it changes values you set which is something I noticed on a previous pedal. Seems like great features but just wasn't cool for me. Too much time having to access the editor and work on presets and have values change when you go back and look at it again. Sorry not a fan of SA, I realize many think this is the ultimate EQ+ pedal but was a no go for me. I much prefer sliders and easy toggles of HP, LP filters which also were not that tweakable and the Noise Gate was useless, terrible clamper. Best of luck w it, sent mine back.

A lot of things about this pedal and Source Audio that don't work for me. Sent this one back. I can see where some might find it a good EQ for their use but for me was a no go. For one thing I have experienced params and values changing in the editor after saving them and going back in in a few days. Bands not where I put them, Q different, just weird stuff going on. 2nd pedal from SA same issue regarding the Neuro thing. I though the gate was useless and could not see how the limiter was doing anything. Just hate how the editor works and trying to set values only to have things change the next time you look. I got some over-loading on the signal doing a loop thing and not really pushing or having level problems. Not a fan of Source Audio, some love the stuff but then again some love pedals I just can't use on my rig.

Title says it all.

This thing can sculpt any sound. ANY SOUND.

I recommend using the neuro app. It'll just make things easier

Single coil buzz bothering you, but you don't wanna lose the tone and high end .. No problem! Low pass filter, boost the 5-7k a little but cut out anything above it. . boom. Problem solved.

Wanna have a tone for every style music? Country, funk, R&B etc, No problem. Create a preset with each eq.

Wanna tame your fuzz or overdrive or suboctave? Boom, no problem.


Onto features....
The noise gate is pretty legit, but lacks control. It works wonderfully, but again i wish we had more control.

The limiter lacks features too. I'm not sure I've ever heard it work.. I've loaded some crazy loud sounds (stupid loud) on the c4 pedal.. The limiter on this didn't seem to prevent any peak. The sound was still crazy crazy loud.

Other than that, the pedal functions great.

Simply put an EQ shapes tone and what's special about this pedal ais that it allows you to find a tone, store it, and recall it easily - so you don't struggle to find sweet spots in your sound.

The SUPER power of this pedal is in how it integrates the One Series family of pedals - there is an intentional design that brings all these pedals together through software.

When the pedals are connected to a "Neuro Hub" device you can store entire "scenes" of sounds on your computer in the Neuro Desktop app. The architecture is a game changer for a recording musician that must recall pedal settings within tracks.

The Source Audio guys are technical AND nice. Their overall technology vision works well for musicians - and this pedal turns my Strat into whatever I want.. -- -- --- ---- That's just cool.

Possibly the best EQ out there. Does it's job in total background silence. Easier to use than you might think.
Very pleased...

Easy to set up, easy to use, no noise. It stays on all the time for use with my Boogie TC-50. Good investment, great advice & service from Jordan.

I purchased the EQ to have the ability to include acoustic capabilities on my board. I have not had a lot of time to explore the EQ regarding additional features. Things I really like are the software, programable boost and EQ range, separate EQ for dual input and out, ease of use, vivid display, midi capabilities, 9 volt DC, and the sound is absolutely on par with any EQ I've used to enhance an instrument.

First I would like to thank Reid Bright my sales engineer for everything we have done together over the past couple of years. Helped me a lot. The EQ2 is a great pedal. I found out that I to use the power supply that comes with it. If I used the power supply adapter Voodoo it made a crazy noise. This eq pedal has a ton of options on it. There is a lot to learn. I just wish there was more videos on how to use this pedal.(More in depth)Pedal sounds awesome though. Made my rig come alive. Very well pleased.

Pricey but definitely a high quality device, which I have found to be the final piece in fine-tuning my tone.

#1 The sound you can get from this pedal for different guitars and pickups is phenomenal. That's the most important thing after all!
The ability to store 8 settings on the pedal without connecting to free SW on your computer to manipulate everything that this pedal is capable of. It's a lot! Parametrically, you can tweek so much using the free SW on your computer if you want to and, save up to 120 different modes if that's what you need!
I use 8. It's enough for me.
Sounds Awesome.

Thanks Source Audio!!!

I've bought Sooo many EQ pedals since the 80's and none of them compare!

Bought this to replace a GE-7 that is over 20 years old. I don't have a lot of trust for digital gear but the SA EQ-2 does have a very nice and transparent tone and very precise adjustments that I did not have with manual slide graphic eq. It has so many more features, most of which I will never use, but the parametric function allowed me to set the freq of each band to optimal for electric guitar. I use this in the effects loop of Marshall JVM amps and it allows me to clean up some low mids and boost the high mids giving an incredible feel to my tone. So far, I am very happy with this product, and it is an improvement over the GE-7. I have only had it a week so unable to testify as to the durability but no gliches in the adjustments or other problems associated w digital electronics, as I have experienced with other products. Thanks again to Paul Rowan and all the Sweetwater staff for getting this to in timely manner with no troubles!

I've had an MXR 10-band GEQ in my rig forever. I use it in the FX Loop, last in the chain of effects as a final EQ. It's a great, solid EQ.

When I recently switched to a stereo rig, I was forced to move the MXR GEQ to before my stereo effects, which really changed the overall timbre of the rig in a negative way. I just couldn't get the rig to sound the same, even in mono.

The Source Audio EQ2 allowed me to put an EQ back at the end of the effects chain, and I quickly dialed in my familiar tone. I noticed right away how much more defined my overall tone now was. The audio quality of this unit is spectacular, and can handle the hottest FX Loops. If I should ever go back to mono I'll continue to use this EQ over the MXR.

The Source Audio EQ2 also solved another issue that always bothered me, having to compromise on the EQ to suit my 3 main guitar tones (clean, crunch, & lead). Now I have 128 MIDI presents allowing me to have specific EQ settings for my variations of those 3 main tones.

Can't wait to hook up my tablet and access all the other features of this EQ, but right out of the box it's a winner and on my pedalboard! One of the best pedals I've bought in a long time.

This pedal has a pretty steep learning curve.. I have a vypyr pro and it also has a steep learning curve, after 4 months still am figuring things out with it... There is also a software component to this pedal. I kinda looked at the software and
determined, in my case, it was a bit too much to bother with. I own a couple of the SA eq1's and they are very ezy to use. The EQ2 is far more complicated, and I use it more or less the same way I use the original. It's a good pedal but you may spend more time setting it up than you will playing your guitar. What I do like is the stereo outputs (major upgrade if you have stereo pedals)and the 10 band eq vs the 7 on the original. The tuner is there, but for me not too practical, I personally like a tuner in my chain I can quickly get in and out of. I give it a 4 just cuz it is a little too gimmicky.. way to many parameters for the avg guitar player. If you want a good mono eq try the older brother first. If you don't have a stereo hook up it may be the best choice and about half the cost

I didn't realize what a sonic difference this pedal would make and all I can say is, "WOW!" Best of all, I can EQ different makes of guitars (Strat, Les Paul, etc.) and save the settings, then recall the setting for that guitar. I still haven't even begun to explore the possibilities! I can highly recommend this pedal to anyone!

This pedal is excellent. If you are searching for an EQ, to enhance your tone, with the options to change it on the fly depending on what your playing, this pedal will provide you multiple EQ configurations all available by pressing the button. You could either set up the EQ using its buttons or an appplication downloaded to your cell or tablet. The EQ 10 bands are enough, to keep it simple, but giving you multiple frequencies to play with. Could be more expensive than other options on the market but it is worth it.

I love this pedal for the ability to fine tune and program all the EQ parameters. But I hate the single-knob control. I play multiple instruments and commonly set up guitar (or 2) and violin for a gig, and sometimes mandolin. The programmable multiple presets are GREAT! Especially to swap between a quacky sounding carbon fiber violin with piezo's, and an archtop guitar with P90's. Sometimes a Tele and sometimes a Martin. The desktop software is versatile and fantastic, and offers very granular control over several parameters to program the perfect preset for each particular instrument or song. The mobile software is pretty good on my Android phone. BUT, in a live situation, in the middle of a set, the single "Encoder Knob" is a deal breaker for me. First gig I played with it, at a venue I'd never seen until 25 minutes before show time, I couldn't make any adjustments. Instructions say to hold down the knob & turn it to select the frequency band, then turn the knob (without holding it down) to adjust that frequency. Reality was that every time I wanted to change a frequency band, I had to press and turn the knob several times before it would "catch". Oh, and if you double-press the knob, it flattens all the bands. Which means that several times I ended up flattening my presets just as the next song was kicking off, rendering the pedal useless until the ~next~ song when I could cycle through the presets again. It's a GREAT pedal if you have the right presets set up and you don't have to adjust anything on the fly, or if you have time and patience to fumble with "the knob". OR, maybe if you want to leave your phone plugged into the pedal board to have a way to make quick adjustments. For me, no. It's coming off my board this morning.

The Source Audio EQ2 is very flexible and powerful. With the multiple presets, you can adjust your tone quickly on the fly. Having it in a standard pedal size also means it doesn't take a lot of room on my board.

While it is easy to make changes on the fly directly on the pedal, it really shines if you create your presets connected to a device. I connected it to my computer and with the USB connection it is a 2 way connection that shows the adjustments immediately. This makes its fast to make adjustments and try them to see the results. I had a number of distinct presets in short order. Once stored I can quickly switch presets on the pedal as needed or I can make small adjustments if I want.

If you'd prefer to have hardware sliders on your pedal for quicker on pedal adjustments, you might like something else. I prefer the increased flexibility and the visual presentation when you switch presets that you don't get from hardware sliders.

Definitely recommend this pedal if you want something beyond a single setting at a time EQ pedal.

For me, this was an upgrade from an MXR 10-band EQ pedal. Although I loved the MXR for years, being able to use only one setting was a serious limitation. I had seen the previous Source Audio EQ pedal, but it seemed not quite there as far as number of bands and options. So when this EQ2 came out, I knew it was the one I was waiting on. I would have been happy enough if the bands and Q were fixed, but finding out they could be adjusted is next level. In effect, it's a hybrid graphic/parametric EQ, which is amazing. Sometimes you just have that little frequency that needs to be notched out for a certain pickup or amp or pedal. This allows that fine tuning.

I love that there's a clean boost. I have it after drive pedals, so it's nice just for a pure volume boost, or I can do a volume boost and a slight bump of the mids for leads. Another good use is to put it after a pedal that doesn't have a level control and tends to be quieter when engaged. I have a synth pedal like that. Now, I could have a preset just for use with that pedal.

I switched to expanded preset mode to get 8 presets and also plan to use a tap switch to split channels, so I can have up to 16 settings (2 per preset). That's more than I'll even need, so won't crack into MIDI anytime soon, but nice to know it's there.

The tuner was a nice bonus. It allowed me to kick my old tuner off the board to save power slots and space. You can set it up to be activated several ways. I like the setting where you press down the knob and button together. That activates it immediately and mutes your signal.

The only slight negative I found was probably just a limitation of physical internal connections, so I don't deduct any stars. I was going to try to use the FX loop function to have all of my dirt pedals in a loop, so that on a given preset I could have one channel of the EQ pre-dirt and one post-dirt. While the routing actually worked, the thing I wasn't aware of was that you have to have the pedal engaged to hear any of the pedals in the loop. So, if you wanted to play your drives without the EQ pedal on and just click it on when needed, that wasn't an option. If you want no EQ in that scenario, you'd have to leave it on all the time, perhaps with the split channel and tap switch with one channel set flat and the other set to the EQ curve you wanted, switching between with the tap switch. Wasn't a huge deal, as I decided I'd rather use it a different way, but wanted to mention that in case someone was considering that specialized use case.

The Source Audio EQ2 Programmable Equalizer Pedal is the missing link for my home studio set up ! Instead of changing guitar patches,amps and various other elements of my sound; I just tweak the EQ2 and done. There is plenty of space to save multiple settings, and with the additional free software even more room to create your own EQ2 library. I also run vocals through the EQ2 to change the quality of my tracks without the use of a bunch of CPU hungry plug ins. Game Changer for sure ! Play on :)

I am splitting my bass guitar signal thru this EQ pedal for a dirty channel and clean channel adding effects to each. This pedal allows me to EQ both channels independently to really dial in my tone!!!

Using just the pedal, it's a bit tedious to setup, but you can configure 4 programmable EQ options which can be recalled or switched out with the push of a button. That alone makes this a nice pedal. Then, if you plug it into a computer and install the free software from Source Audio (Neuro Desktop), this pedal goes to an entirely different level. Through the software, you can adjust the frequency center and Q for all 10 bands, essentially making this a 10 band parametric EQ. I've been playing around with using it to target specific frequencies for boost or cut to remove unwanted sounds and mildly boost some of the tones I want. In addition, you can switch on a limiter, noise gate, high pass filter, and a chromatic tuner. This pedal is powerful enough that you can easily make an instrument sound like junk if you're not careful. I got it for the ability to program in settings for a few different tones for various songs. I can already tell I be using it for much more.

The EQ 2 has pristine audio quality, a non existent noise floor and the feature set is ridiculous... This one pedal replaced a tuner, limiter and the first gen Source a Audio EQ on my board.
One application is pre and post EQ on your board. instrument or efx loop into input 1, end of your efx chain into input 2 and then to your amp or complete the efx loop. Use the second side to restore any body lost in the chain.
Another is to gain balance instruments with varying output levels. I often run a passive 4 string P bass and an active PJ 5 string.

Among all the fantastic effects available today, both analog and digital, the EQ is probably the least sexy. However, its utility is similar to that of a tuner, vital yet often taken for granted. Whether its to change your tonal shape to accommodate a different guitar at the back end of the set, to adjust for that little pub with the odd shaped room, or to simply enhance your rig to bring out its true potential, an EQ pedal is an invaluable tool for musicians.

Build quality is wonderful, and a nice upgrade from the older version. The expanded spectrum, displayed on a much clearer and brighter grid, will make this unit more useful to bass and full frequency players. The included limiter and noise gate are a wonderful addition, and somehow Source Audio managed to cram a tuner inside this unit as well.

The EQ2 brings all the wonderful tone shaping efficiency of the older version's four presets, and expands its functions in every dimension. Eight presets and band adjustments(center frequency and width) are available by interacting with the units eternal footswitch and knobs. The unit really shines when linked to the Neuro app. Easier preset adjustment, parallel or parametric operation, different routing configurations, midi programming, and active preset sharing all become available via your computer of smartphone. The EQ2 can even run two independent EQ curves for the left and right channel, enabling for example, compensation for two different amps in a stereo rig, or having one curve before your amp and a different one in the loop.

The possibilities are nearly endless, allowing a surgical level of tonal sculpting. This unit is worth every cent of its release date asking price. Get one!

The EQ features of this pedal sound really good, but it's the added stuff that sold me. Now I have my tuner, limiter, noise gate and HPF needs covered in the space of an EQ pedal, love it. The editor is amazing, though I mainly use the pedal just by itself now that it's all set up. Very versatile and easy to navigate.
