Boss Chromatic Tuner

The Boss Chromatic Tuner which evolved from the world's top selling stage tuner, the Boss TU-2, 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. It also 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.

Choose between Chromatic or Guitar/Bass tuning modes, and enjoy visual pinpoint tuning verification with the Accu-Pitch Sign function.
