The New World-Standard Tuner Has Arrived
The evolved and improved version of the world’s top-selling Boss TU-2 stage tuner, this is the new 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 new-standard tuner that no guitarist or bass player should be without!
