The BOSS TU-80 brings super-accurate LCD tuning to a very affordable price, while adding unique features like a built-in metronome and Accu-Pitch™. The pocket-sized TU-80 runs on batteries and can tune almost any instrument, thanks to a chromatic tuning mode. It even tunes 7-string guitars and 6-string basses—putting the TU-80 in a class all its own.

Thin is in. That's why the new TU-80 was designed to be slim and light enough to fit in your pocket. Best of all, it sports reliable and accurate BOSS LCD tuning, along with Accu-Pitch, which plays a tone when you're in tune. No more looking down at the tuner!

Thanks to its chromatic and flat tuning capabilities, the TU-80 can tune just about any instrument—from guitars and basses to strings, brass and woodwinds. A handy Reference Tone Play function lets you hear the correct pitches, while a built-in metronome with seven rhythms and 10 beat variations makes practice more effective. No other tuner has all this!
