Boss TU-3 Chromatic Guitar Tuner

The new industry standard!

The original TU-2 was the standard by which all other tuners were based.

The world’s top-selling stage tuner, the BOSS TU2, evolves and improves with the debut of the new TU-3. Housed in a really tough BOSS stompbox body, featuring a smooth 21-segment LED meter with a High-Brightness mode, the TU-3 cuts through the brightest lighting conditions. Choose between Chromatic or Guitar/Bass tuning modes, and enjoy improved visual pinpoint tuning verification with the Accu-Pitch Sign function. The Boss TU3 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 new-standard tuner that no guitarist or bass player should be without!
