Sweetwater Advice

  • Jared Kalish

    This pedal is an absolute lifesaver when you're on stage. I can't tell you the amount of times my bass has gone out of tune after I've been really laying into it for a song or two. Just look down, stomp the box and get yourself back to sounding like you should.

    Best pedal tuner I've ever owned! I am highly impressed by the quality and accuracy of this beautiful addition to my stage gear. Intonation is very important to me. All of my basses are set with a very expensive strobe tuner after every string change. I compared the two and was very pleased in the accuracy! My two guitarist are also purchasing one after they used mine. Thanks for a Great product that I'll use for many years! Also, Thank you Jared, at Sweetwater for your Oustanding customer service as always!

    Simple, yet way better/more responsive (immediate reading) than my Korg Pitchblack tuner. I use the Bypass for a Royal Blood type setup too

    Powers my whole board...works great

    It's a Boss Tuner pedal, man...no brainer. Powers my whole board of 4 other pedals and an A/B box. No complaints. Gets the job done every time. Definitely didn't want to skimp out on a tuner...gotta be in tune. Can't beat it as far as I'm concerned.

    Boss TU-3

    Boss is synonymous with rock solid build quality and reliability.

    Simply put...I needed a tuner for a small pedal board I put together. I've had a TU-2 for ages and it's never let me down.

    If it ain't broke...don't fix it. I bought a TU-3 and haven't looked back. Excellent tuner and when you hit the pedal it cuts off the signal so you can tune in silence and/or change guitars without making a fuss.

    TU 3

    Love it. Dead on and quick to to find the note and tune. No bouncing around. Very clean through my rig.

  • from Houston, Texas October 20, 2016

    Boss TU-3

    Perfect....tuning is so much easier now.... with drums banging and guitars screaming, I can now perfectly tune my bass. Easy to use with a display that's easy to read while standing. Best investment I've made in a long time.

  • from Carlisle, PA June 28, 2016


    I have been using an ahdown tuner box and it had a lot of trouble picking up the B string. This T-U3 Tuner is excellent and picks up the B string with no problem. It's easy to read and works great!

  • from AZ April 30, 2016


    Title says it all, WOW, easy, accurate, convenient, no wonder it is the best pedal Boss sells.

    A must have

    I had never used a tuner before always tuned my bass by ear now my daughter is playing bass and the boss tu3 is a must have . It's easy to use and very quick.

  • from Las Vegas, NV March 4, 2016


    This is the tuner! Great solid build, too many options! Works perfectly. If you not have of these,,, get one

  • from Athens, WV February 2, 2016


    This is an absolute MUST HAVE if you're a guitarist/bassist. I'd used an old Seiko ST737 I bought when I started playing up until receiving this, through my amp's send. It was, to put it politely, garbage. This pedal is just wonderful. I feel like I'm in the lap of luxury, going from that AAA battery Seiko POS to the TU3. It's pretty much the industry standard for tuners, right? I should've gotten one 14 years ago. The display is bright. VERY BRIGHT. I turned the brightness up all the way and it was uncomfortable to look at, and my studio is very, very, very well lit. No worries about not being able to read the display under stage lighting.

    It's also spot on accurate. I used it to check, double and triple check the intonation an Ibanez 7 string that the Seiko determined was not in tune.

    Stop reading this. Buy it. Just do it. I bought it on a Tuesday, it was here Saturday. Sweetwater doesn't mess around.

    Boss TU-3 Tuner Pedal w/Bypass

    When you're strings begin "to go" and don't register anymore on your present tuner, generally your strings will still register on the Boss TU-3. For me, that means that I get the most out of my guitar strings and not change them sooner than really needed. I'm sure the same would apply to you too, if you also, had a Boss TU-3. This pedal is not only the best tuning pedal I've encountered so far (best indicator), but it's also an investment by saving money on new strings (when to ultimately change your strings).

    Boss TU-3

    Looking for a tuner that will tune my 5-string bass. They all say they do, but this one will. I have tried a lot of the others. None are as accurate or as fast as this one. The Boss TU-3 worked better than a rack tuner. My sales rep from Sweetwater convinced me to try it. His advice was spot on. Once again Sweetwater came through for me. Awesome product support. They know what they are doing !!!

    This tuner is easy to use and reliable. Tuning is accurate. Visibility is excellent. There is absolutely no noise or popping sound when activated. The price is very reasonable.

    Solid pedal!

    this is really a solid and well constructed pedal. It will not fail, and would definitely take a beating on the road. the bright mode is very nice for outdoor performances. Very nice.

    I was blown away by Brandon! He checked in many times to make sure everything came as expected. I liked the personal calls. With all the technology out there it was nice that someone cared enough to call, and not just once. His assistant Nicki was also extremely good at getting back to me with answers to my questions. I will definitely recommend Sweetwater to all my musician friends. Great job Sweetwater! Your service and support is outstanding!

    Great tuner

    So I bought this to use with my Taylor 314ce w/ the Fishman Prefix onboard blender and after I figured it out and got acquainted with it, I love it! At first it was being kind of flaky and fluttering a lot, but a quick google search told me that I had the volume too high and it was "overdriving" the pedal. Also, I play with the bass slider all the way up and that creates a little bit of background noise. So, If you keep your volume low and EQ flat while tuning, it's as accurate as can be! Not to mention tough! I think this thing is gonna be around for a WHILE.

  • from Westfield, MA May 23, 2014Music Background:

    Boss Chromatic Tuner

    AWESOME tuner. I bought this pedal as a less expensive way to power my other three pedals. I already had a Boss TU-10 tuner which was OK. As a tuner this is easy to use, quick (no needle jumping from side to side as you zero in the pitch), easy to see, and accurate. My suggestion to anyone looking for a tuner is to skip working your way up from the $12.00 models and just spend the money up front. It will save you from wasting your time and money to get where you will end up any way.

    Boss TU-3

    The Boss Tu-3 is unsurpassed as a pedal tuner. It's already saved me at least a $100 in set-up fees because it's easy to fix a guitar's intonation without going to a guitar shop. Plus Kurt from Sweetwater is great to work with.

    This pedal is perfect for me as a frontman in the band. the quality of this pedal is what i expected from boss. strong and road ready. thanks to sweetwater for advising me with my purchases. this thing lights bright on stage and takes zero quality away from my other pedals and over all sound. invest the money in this, you won't be let down.

  • from Chapel Hill, NC January 2, 2017

    Does what it claims to do

    This tuner is top of the line. It is simple to use and seems quite accurate. In other words, it does what Boss claims it will do - and it does it quite well. However, in my goal of decreasing the size of my bass pedal board, I found it to be too large, so it's back in the box. In it's place I'm using a TC Electronics polytune2 mini.

  • from July 7, 2016Music Background:

    Very Accurate

    This chromatic tuner is a very accurate tuner pedal. I am happy with it and I take it everywhere. It is gig worthy. This is great for guitars that get out of tune quickly or tuning a guitar to a different tuning. I don't have enough guitars to have a different tuning for each one, so this is nice to have. If you are looking for an amazing tuner pedal that works, is very accurate, and is gig worthy, I suggest you buy this!

  • from MT July 6, 2016

    Don't forget the AC Adapter!

    I bought this tuner on the advice of a well known, respected guitarist, and it's all I expected it to be. The display reacts quickly, and the high visibility meter makes it easy to see in all types of lighting conditions. I definitely recommend it, but a word of caution: the pedal runs on battery power unless you also purchase an AC adapter. The unit is powered up whenever you have it jacked in, so w/o the adapter the battery is very short-lived. Could be a problem when gigging, so bite the bullet and purchase the AC adapter with the unit.

    One Strong Tuner

    Although now there are tuners with bigger, better displays, more display options, other tuning modes, and can tune more than 1 string at once. But, none are built as strong as this one. The buffer in this pedal is very good compared to a lot of other pedals I've tried. From my experience, the other tuners don't have a buffer. When I ran it first, it gave me consistent tone and improved it. But, this tuner easily competes with the others because it also has a lot of features such as modes of tuning, pitch, flat modes, bass, high brightness. It can sometimes be a little fidgety with the tuning, but its a solid tuner. Worth the money, and it improved my tone. It will last a long time like all other Boss pedals.

    Boss TU3 Tuner

    Love the whole process !!! Great price and even better service ... I needed a Boss tuner and did the usually price comparison and web search routine and I kept on coming back to sweetwater ... Well sticking true to my procrastinating self I ended up buying the pedal 3 days before our gig not only did I get a phone call telling me the pedal was in stock and on its way ... It arrived in 2 days opened the box to find my tuner and numerous bags of candy !!! It made my pedal board for the gig and the band loved the treats ... My go to source for all my equipment

    Boss TU-3 Chromatic Tuner

    Outstanding addition to our "toolkit" especially like the bright display and the fact we dont have to balance it on our knee or anything. Just what we needed for our guitars. .

    Tuning to the Nth degree!

    This tuner is all you need indoors or out! Easy to use and fits perfectly on my pedal board. My only 1/2 star downside is that sometimes electronic tuners can be TOO accurate. When I first used this tuner I caught myself "micro-tuning" to satisfy the dial. But when you hit that 'tuned' indication, brother you are in tune! Wouldn't trade this product for 10 others. Boss has this stuff figured out. Good Luck with yours!

  • from Seattle, WA October 6, 2011Music Background:

    Never do a gig without one!

    Every guitar player should have a tuner in their pedal board. Period!!! You can't go wrong with a Boss tuner, or a TC PolyTuner, or even a Korg tuner. Doesn't matter which one as long as you a have a tuner. But for me I always fall back to the Boss TU pedals. Their TU-3 is one awesome pedal you can count on - well in this case, "step on." Ease of use, rugged, dependable, never lies to you... I love it!!

  • from December 31, 2015

    nice TUNER

    I bought this tuner for my Les Paul. The instruction manual does not say that you can not leave the guitar plugged in the tuner when using the 9V battery. It will drain the juice of the battery in 2 days. So I bought an external power adaptor and I can tune my guitar any time I want. The LEDS are bright and easy to see. Great tuner.

  • from Kailua, HI August 23, 2013Music Background:

    There's a reason why it's the standard.

    This is not the best tuner on the market...some research will find tuners that are more accurate, faster tracking, true bypass, etc etc...but this tuner remains a classic because it never fails. I have had one since it first came out in 2010, and it has been with me at every show since. From rolling around in the gear bag all day, to being stepped on every night and thrown in the back of the truck afterwards, this pedal takes a beating and never fails. The display is plenty bright and easy to read, the tracking is fast, the switching mechanism is predictable and quiet (no loud clicks from true bypass switches), and the signal buffer is effective (not great, but not problematic unless stacked up with 2 or 3 other Boss pedals). All in all a great tuner, you really can't go wrong with Boss.

  • from United States May 7, 2013Music Background:

    Good, but not the best

    This tuner has always worked great. I used to have the Tu-2, and then a buddy of mine got the new TU-3. When we played shows it was great, except for one part. Anytime we were outside on a bright day it was impossible to read this thing.

    I have switched over to get a peterson classic stomp now so that I can see it outside during shows, but otherwise this product is amazingly accurate and did a great job for many years at keeping me in tune.

    Boss TU - 3 Tuner

    Great pedal so far, great construction.

  • from September 19, 2011

    rugged but needs power

    This reliable tuner/disconnect would get 5 stars if the package included a power unit. When things are plugged in to the input, it is "on" so the battery will run down if you leave it plugged in. I guess I could go find an aftermarket transformer, but I'm unsure what voltage to use. Boss needs to make this a plug-in power unit straight out of the box (without jacking up the price...transformers are inexpensive).

  • from Charlottesville, VA June 20, 2014Music Background:

    Pedal stopped working, barely used.

    I used this pedal about a dozen times over a two-year period when it just stopped working. It was a month outside of warranty when it happened, so now I'll need to gamble on returning it for repair at $40/hour (billed at 10 minute increments, so 70 minutes of repair = $80, plus shipping) or replacing it (with something else).

  • from April 17, 2017

    Keeps Failing Giving Up

    I know this gets rave reviews, but I and the guitarist in my band have this tuner, and we both had the exact same intermittent problem with it. The display suddenly starts scrolling wildly and the tuner doesn't work.Thank God for my little plug-in tuner. The guitarist gave up on his and got different model. I'm finally giving up on mine. That's why I'm here: looking for another tuner. Tuners are supposed to be pretty simple. They should work. Especially when they're as structurally well-made as this one.
