The world’s top-selling stage tuner, the BOSS TU-2, evolves and improves with the debut of the 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!

Would by it again


Got it before I got into pedal board use. It continues to serve its purpose. However, on a pedal board the location must be considered because of the depress switch. A button switch would make it perfect for the toe tap unless you're using a bypass looper. The cut off for the tuning mode gets me in and out fast. Very easy to read.
