The World's Best-selling Stage Tuner — Improved!

The TU-3 is more than just a rock-solid, dependable tuner for your guitar rig — it's practically a modern legend. The latest member of BOSS's world-famous TU Series, the TU-3 is made to work night after night, stomp after stomp. And since it now features a high brightness mode for your outdoor summer festival gigs, it'll work day after day too — you can bet the TU-3 will be glare-free, offering up a large, clear LED display to help you get in tune.

As far as display goes, you have a few choices in how you prefer to tune up — whatever you do, the "Accu-Pitch" function gives you visual verification whenever you're in tune... very handy. All in all, the TU-3 has a chromatic mode for tuning by note name, then there's Guitar/Bass mode that lets you tune by string number — even string number for 7-string guitars and 6-string basses. Finally, there's a Guitar Flat mode for those of you that like to rock "Drop" tunings, down to six semitones below standard.

The BOSS TU-3 is definitely a pedalboard must have — and its predecessor, the TU-2, was the world's best-selling tuner pedal for good reason: it just works. What's also cool about the TU-3 is that it can supply power for up to seven BOSS compact effects pedals, so you can keep your pedalboard neat and tidy... and your power strip free of nasty wall warts. Get in tune, stay in tune — get the BOSS TU-3.

BOSS TU-3 Guitar Tuner Pedal Features:
  • Stompbox-style guitar tuner pedal
  • 21-segment LED meter with brightness control
  • High-Brightness mode enhances meter visibility outdoors
  • Accu-Pitch Sign function provides visual verification when tuning is complete
  • Chromatic and Guitar/Bass mode (tune by string number, with support for 7-string guitars and 6-string basses)
  • Flat tuning is supported with Guitar Flat mode, which allows for "drop" tunings up to six semitones below standard pitch
  • Tuner automatically mutes when the tuner is on
  • Can supply power for up to 7 BOSS compact effect pedals

Here's an unbeatable value and a pedalboard must have — the latest version of the world-famous TU Series tuner pedals, the BOSS TU-3.

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.

Great pedal so far, great construction.

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.

Sweetwater Advice

Steven Dilmore
The Boss TU-3 is bright, accurate, and keeps you in tune. Simple enough, right? It's a tuner, it does what a tuner is supposed to do. Of course, it can power up to SEVEN OTHER Boss compact pedals too! Plus, it has a variety of modes to meet your needs, and is built ridiculously tough. I used mine to drive a few nails when I was hanging pictures the other night (true story). This is the one pedal you cannot do without. Even if you never use another stompbox for the rest of your music-playing life, you should use the TU-3 every time you pick up your guitar.
