You'll won't likely make it out to any live show without seeing a Boss chromatic tuner on the stage. Boss's renowned TU series have become synonymous with assured and reliable intonation, and the Boss TU-3 will consistently keep your game in check with its durable stompbox style switching, C0 to C8 tuning range, easily visible 21-segment LED meter, tuning capabilities for seven-string guitars and six-string basses, and flat mode settings for up to 6 semitones below standard pitches. This pedalboard staple can also power up to seven Boss compact effects pedals when used with an AC power supply. See why Boss remains the boss in the arena of guitar tuning pedals with your TU-3 Chromatic Tuner Pedal.

Easy-to-Read 21-Segment LED Meter

You'll always be able to see how in or out of tune your axe is with a simple glance at your TU-3's easy to read 21-segment LED meter. Set this baby to its chromatic setting to get a quick reading of any of the twelve notes in the chromatic scale. Plus, your TU-3 has a high brightness mode to help you read your meter easily for when you're performing in outdoor settings.

Wide Tuning Rage

Aside from having a chromatic setting, your Boss TU-3 also features a guitar and bass mode. This baby also has a flat mode for a wider span of tunings that goes up to six semitones below standard pitches. Don't use a standard axe? No problem! Your TU-3 can also handle tunings for seven-string guitars and six-string basses as well.

Ready to Rock for Any Setting

No matter what the setting is, your Boss TU-3 is always ready to go. Just set it down, plug it in, and you're ready to rock for hours with consistently reliable tuning right at your feet. This baddie is built with a durable metal chassis and is tough enough for continual use, and its stompbox-style switching makes checking your axe's tuning as seamless and noninvasive as possible.

Power to Spare

You have the option of using a 9-volt battery or an AC adapter to fuel your TU-3 with power. If you do decide to go with the AC adapter, then you can daisy-chain your TU-3 and reliably power up to seven Boss compact effects pedals. You'll have fewer cords to worry about, and will be able to keep your pedalboard tangle-free show after show.

Why Have Two Outs?

One often-overlooked benefit of the Boss TU-3 is its two 1/4" outs -- one regular out and one bypass out. The bypass allows your signal to go un-muted as you tune, and your regular output mutes your signal when your pedal is engaged. The muting features on this baby allows for an effective kill switch that can really open up the doors for some sharp signal kill or even strobe effects.

- C0 to C8 tuning range
- Durable metal chassis built for repeated use
- Brightness controlled 21-segment LED meter
- Guitar Flat mode provides drop tunings up to 6 semitones below standard pitches
- One 1/4" input, one 1/4" output, and one 1/4" bypass out

Customer Reviews
4.5 out of 5 (34 ratings) Rate and Review This Product
zZounds has verified that this customer bought this product from us. "Cost effective 'road worthy' tuner"
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. Feature: 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. Overall: Overall a 9 - again, hate the adapter, but this product itself is worth every penny.
Style of Music: Bass and guitar - power metal and christian rock

zZounds has verified that this customer bought this product from us. " just buy it!"
Overall: 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.
Style of Music: anywhere where loud electric guitar is needed!
