"Cost effective 'road worthy' tuner"

Overall: 4.5 out of 5 stars
(see rating details)
Verified Customer zZounds has verified that this reviewer made a purchase from us.
Overall a 9 - again, hate the adapter, but this product itself is worth every penny.
Sound
I've used this for both the bass and guitar in live settings and it's done everything I could want it to do. If you take the time to learn how to switch the modes, there are no issues at all. I love the mute/gate when it is engaged as I do some bass playing for religious services and it is a great to be able to tune/adjust quickly on the fly. The LED lights are nice and bright and visible when the stage lighting is bright. Additionally, I've found the accuracy of the tuning to be spot on.
Features
Most useful features described above. However, if you're going to use it alot, get a power adapter. This thing loves batteries. But DON'T buy the Boss one. I bought the "one spot" adapter and it has held up far better with no issues. Didn't give it a 10 due to the adaptor Boss has and the fact that it loves batteries.
Ease of Use
I read manuals unlike most people. So if you read the manual, it is SIMPLE to use. I browsed through the little manual in the box and had it up and running for both guitar and bass and can now change it on the fly.
Quality
Boss - always has rugged dependable stuff. Their adapters suck though. Get a 'One Spot'.
Value
I have a Korg rack tuner for bigger gigs, and I use this for smaller ones. Well worth the money for the smaller gigs but could be used for large ones as well it that's your preference.
Manufacturer Support
Never have needed support of any kind. Says alot about their products if you ask me.
The Wow Factor
I've always been partial to the simplicity/look of MXR boxes as the Boss boxes are a bit bigger. But I have no issues with this one at all. It has already received its share of nicks and bumps from consistant setup and tear down - that makes it "prettier" in my opinion.

"Indispensable for staying in tune on stage."

Overall: 5 out of 5 stars
(see rating details)
Verified Customer zZounds has verified that this reviewer made a purchase from us.
Assuming it doesn't wear out or die prematurely, I would definitely replace it with the same model.
Sound
It's a tuner and isn't supposed to affect the sound.
Features
Incredibly practical to have highly visible, silent turning available while on stage.
Ease of Use
Easy to turn on and off. One of the visual tuning aid modes is very good, the other less so. I have a feeling they could come up with something a little less busy if they worked on it. It's very clear when the tuning is dead on, sometimes a little less clear as to which way to adjust it.
Quality
Seems very rugged.
Value
I haven't seen many similar tuners. It's definitely worth the extra money as compared to the Boss non-pedal tuner.

I used this tuner for a week now, I really like it. I just can not understand why I am blowing through batteries so fast. Do I have to unplug the pedal every time I am done with it? I step on it to turn it off but the next day I go to use it, the battery is dead. these batteries are almost $10 a piece. maybe I am doing something wrong. this is my first pedal. the Pedal Works like a charm it is very accurate.

"It's a Boss"

Overall: 5 out of 5 stars
(see rating details)
Verified Customer zZounds has verified that this reviewer made a purchase from us.
I honestly wasn't expecting much, but when it arrived I quickly changed my mind. It was kind of funny, because when I opened it a few papers flew out of the little box it's in. It sure does it job, very very accurate if you know how to use it!
Sound
Thud! If you drop it, it makes a thud, nut this thing is built to last.
Features
I really like how of you want to tune your guitar to drop D or anything, it will show you how far you are from it. The little LED lights are spot-on with pitch accuracy.
Ease of Use
Very easy. It's so simple and so effective, best tuner out on the market. Except for maybe Gibson's Min-etune thing.
Quality
It's built like a tank. It's made of metal and pretty darn durable. I dropped it one time, and there wasn't even a scratch!!!
Value
Well worth the $100. Could be $85, nut I'm kinda cheap. Well worth the money for sure. I entered in everything as 5-stars, but it wouldn't keep them for some reason.
Manufacturer Support
No, but I'm sure they're pretty Boss-y
The Wow Factor
WOW! Its an essential, and I was pretty picky about pedal tuners, since I can't really hear myself on stage or practice. This little thing is really helpful as well as convenient.

Great tuner. Well built. Great buffer. Consistent tone. Will last a long time.
Sound
Works as it should. The buffer in it is very good. Gives you consistent tone when ran 1st before all your other pedals, but after a fuzz.
Features
The different modes for tuning are super useful, and high brightness mode is helpful for bright environments.
Ease of Use
Dirt simple to use
Quality
super well made, bullet proof like all other boss pedals.
Value
yeah its worth the money, but now in days, you can tune more than one string at once, and other tuners have better displays or more accuracy. But this is one is better for tone and built stronger.
Manufacturer Support
nope no need to
The Wow Factor
I rate it super well. Its improved my tone running it 1st. The buffer is one of the best I've tried,

"Excellent Tuner!"

Overall: 5 out of 5 stars
(see rating details)
Verified Customer zZounds has verified that this reviewer made a purchase from us.
I'm a novice and I previously used a super snark for tuning but since getting the TU-3 it's all I use. very easy to use and accurate, I've even set my intonation by it. The only thing I don't like is when you go sharp, say C sharp, the tiny dot that represents # is hard to see for my old eyes. If you run this on battery be sure to unhook the instrument cable from it when your done or it will eat your battery up by morning. plugging the instrument cable into it is what actually turns it on , not stepping on it. zZounds is quick to ship, love it!

I've had it since its first inception in 2010 and am glad I have it on my pedalboard! I bought two of them,one for back up. I don't care how great of a Guitar/Bass player someone thinks they are,if your not in tune all the time,YOU WILL SUCK! and loose gigs.. I play semi-pro gigs that pay! and let me tell you they don't have time for mickey mouse teenage guitarist mentality. If you cant tune your guitar fast and deliver the goods that your expected you don't get a call back.....THIS TUNER HAS SAVE ME LOTS OF GOOD GIGS! and the plus side,no tone loose at all.

"Great for outdoor gigs"

Overall: 4 out of 5 stars
(see rating details)
Verified Customer zZounds has verified that this reviewer made a purchase from us.
The inline Boss TU-3 is perfect for outdoor gigs where temperature changes require frequent retuning. Just step on the pedal, tune offline without disconnecting any cords or turning off the amp, then click again and you're back in business. It also eliminates amp poping sounds when switching guitars. The indicator is easy to read from a standing position.

"The "industry standard" for a reason"

Overall: 5 out of 5 stars
(see rating details)
Verified Customer zZounds has verified that this reviewer made a purchase from us.
This review has been selected by our experts as particularly helpful.
OK so, yea, a tuner isn't exactly the sexiest bit of gear available - it doesn't affect the sound at all (except for muting, which is useful but not fun), and even the case is about as utilitarian as you can get. But you know what's NOT sexy? Being out of tune.So, at some point, you should get a tuner. Yes, YOU. It doesn't have to be this one, but there are several reasons why it should, and only a few reasons to choose anything else. I'll mention those first:1. If you're a professional setup tech or luthier who's setting intonation on guitars all the time, then you should spring for the ultra-expensive rackmount strobe tuner. Not the "digital strobe" version, the real one. Nothing else can come close to the accuracy of a true strobe tuner, and if people are paying you to intonate their guitars, you do need it.2. If you're a touring player with a rack, then a rackmount tuner makes more sense. Again, more expensive, but if you're rocking a rack then you're already in for at least several grand, so the tuner won't be a huge bite in comparison.3. If you're an acoustic-only guitarist who doesn't have a 1/4" output on your guitar, then some kind of "contact" tuner is a better choice. Most of these clip to your headstock and sense the vibration of the guitar that way, so you don't need to plug in. BUT - If none of these describes you, then you need a proper stage tuner, and the TU-3 is the unit that all others are judged against. It has a bunch of tuning modes, +/- one cent accuracy, 21-LED meter, dual outputs (more on that in a second), DC power pass-through so you can daisy-chain other pedals off of it, and that legendary Boss enclosure which is I assume is literally bulletproof. And, the price is about as "reasonable" as you could possibly ask for.
Sound
While a tuner doesn't really do much to the sound of your instrument, that's OK - it's totally not supposed to! It mutes the (main, but NOT bypass) output when it's actively tuning. It does also buffer the signal, which is great for me and most others who run long cables but might be a consideration if you prefer true-bypass.
Features
The tuning is quick, clean, and plenty accurate (although again, this is not a strobe tuner, so intonation is probably not going to be the best). But another thing I love (and actually the main reason I bought it) is the dual outputs. The "Main" out will mute when you activate the tuner function, and the "Bypass" out does not - it's active all the time. This lets you send the "Main" out to your amp, while running the "Bypass" output to a DI or recorder, so you can monitor through your live rig while recording a clean DI signal that you can re-amp later. Your recording engineer WILL thank you for having a DI signal, and this is a cheap and easy way to get it. Finally, it also allows you to daisy-chain power to other pedals if you have an AC adapter and the daisy-chain cables, which is handy if you don't have a separate power supply and cables for each (or if you just want to save space on your power strip).
Ease of Use
For a pedal with so many tuning modes, it's super-easy to use. Just plug it in, push the buttons on the top to select your tuning mode and (if desired) offset, step on the switch, and tune your instrument.
Quality
Three words: It's the Boss. If you've played guitar and/or bass for more than a few weeks, you probably already know what's up, but I'll recount the story of the day I got it anyway: I opened the box, examined it for any issues (I bought this one used), and finding none, proceeded to plug in and test it. From there I picked it up to bring it into the office with the rest of my rig, and promptly tripped over the coffee table, sending the pedal crashing into the wall. My fiancee looked HORRIFIED with the fear that I might have just damaged a pedal I'd just bought, so I couldn't help laughing as I assured her that I was totally confident that the drywall had taken the worst of the collision. And I was right. ;)
Value
Very, very worth the money. There are other pedal tuners out there, and this is the yardstick that all the others are measured against.
Manufacturer Support
Has anyone ever had to contact Boss for problems with one of their pedals? I sure haven't, and I don't know anyone who ever has. I'm not SURE they would survive a direct nuclear strike, but I'm also not sure they wouldn't.
The Wow Factor
I lived without a pedal tuner for years and years, and since getting this one, I feel like a total chode for not doing it years ago. Just buy the thing - your bandmates, housemates, audience, and production crew will all be grateful, even if they don't say it.

Overall: 5 out of 5 stars

Doubt I'll ever need to purchase another tuner unless I get tired of carting this one back and forth.
Sound
Love the tuner so couldn't bring myself to rate it poorly even though it doen't produce sound.
Features
Love the Sweep function and the off standard memorization settings. Our Church piano is tuned at 438(!) instead of 440. My other tuner, though capable of setting to 438, it reverts back to standard on power up.
Ease of Use
Lots of features, so it does take some time to get comfortable with the operation.
Quality
Still have a Tu-2 (?). Not even sure how old it is, but it still works fine. Also have several other foot pedals from the company and all still work.
Value
Great price from Zzounds and this tuner will last forever.

"'s OK"

Overall: 3 out of 5 stars
(see rating details)
Verified Customer zZounds has verified that this reviewer made a purchase from us.
Why in the world would you only have a "sharp" indicator, when almost everyone tunes to "flat"? Sure, you know that d sharp is the same as e flat, but especially when quickly dropping your low string on a e flat guitar to d flat, who wants to even waste that much attention if you only have a few seconds between songs? My son plays onstage with four guitars in four different tunings, some to standard and some flat, so using just the "flat mode" is not an option. Lots of options on this pedal, but I think that's where the problem lies: it's trying to be all things to all players. Overall, it tries to do too much at once and wind up doing it's job less well as a result. Bypass is dead silent, so that's nice. Power supply would be handy if I didn't already have one. Overall, underwhelming. I expected more from Boss.
