PLAY AS YOU PAY
You Can't Rock If You're Not in Tune
It's a nightmare that comes true for almost every performing guitarist sooner or later: you're up on stage, playing your heart out, but something is not quite right. Your fingers are where they should be on the fretboard, but the sound doesn't match up. Your guitar has gone out of tune. You hack your way through the song, then desperately try to tune by ear as the bass player peppers the crowd with stage banter, but you just can't hear well enough to know if you've fixed the problem or made it worse. You've got a little tuner in your gig bag, but that's tucked away behind the drum kit. And you'd never be able to see the display on this dark stage anyway. If only you had a tuner that was always connected to your instrument and could let you easily see what adjustments you need to make. If only you had a Boss TU-3.

Built for the Stage
Everything about the TU-3 points to stage-ready performance. The familiar stompbox shape sits comfortably among your other pedals, so there's no need to run back to your amp every time you want to tune. It's in-line with your signal path, and ready to tune whenever you are. The metal chassis is built for the rigors of the road. You know what happens when gear gets tossed into the back of the van. A cheap plastic tuner isn't going to cut it. This tuner features a bypass output, which mutes your sound when the pedal is engaged. You've worked hard to make your set flow smoothly, so you should tune in silence.

To Battery, or Not To Battery
The TU-3 offers battery operation (with power save mode when disengaged), but can also be powered by an AC adapter. In fact, this tuner can act as the nerve center for your entire pedalboard. With the AC adapter and the optional PCS20A Daisy Chain cable, your TU-3 can feed power to up to seven other effects pedals. Instead of spending big bucks on replacement batteries and wondering when one or more of them is going to fade out during the gig, you can juice-up your whole rig with one adapter! You're in-tune, you're saving money, and your signal chain is organized and reliable.

Easy to Read, Easy to Use
When you're out of tune, you want to get back in as fast as you can. You need a tuner that will tell you what's going on with your pitch at a glance, and give you instant feedback about the changes you're making. No tuner does this better than the TU-3. Strike an open string on your guitar or bass, and a 21-segment LED meter shows you how close you are to the pitch displayed below in red. Whether you're on a near pitch-black stage or playing out in glorious bright sunshine, you'll be able to see the meter in high-brightness mode.

Chromata-whatsis?
The TU-3 is a chromatic tuner, meaning you can isolate any of the twelve tones in the chromatic scale for reference. This makes it easy to set your guitar up for standard tuning, drop D, DADGAD, open tunings, and any other pitch scheme you can think of. This tuner also offers flat tuning mode, which supports tunings down to six half steps below standard tuning.

If you're playing on stage in front of a crowd, you owe it to yourself (and your fans) to bring the best sound you can. Let the Boss TU-3 worry about the pitch; you just focus on your tone.

Product Description

The world's top-selling stage tuner, the BOSS TU-2, evolves and improves with the debut of the TU-3. Housed in a tank-tough BOSS stompbox body, the TU-3 features a smooth 21-segment LED meter with a High-Brightness mode that cuts through the harshest outdoor glare. Choose between Chromatic or Guitar/Bass tuning modes, and enjoy visual pinpoint tuning verification with the Accu-Pitch Sign function. The TU-3 incorporates a convenient Note Name Indicator that can display notes of 7-string guitars and 6-string basses, while the Flat-Tuning mode can support up to six half-steps. It's the standard tuner that no guitarist or bass player should be without.

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!
