Boss TU-3 Guitar Tuner

Boss TU-3 pedal style chromatic guitar and bass tuner replaces and improves upon the legendary, best selling TU2 stage tuner. Boss TU-3 electronic guitar tuners come housed in a tank-tough Boss stompbox road-ready chassis. TU3 features a smooth 21-segment LED meter with a High-Brightness mode that cuts through the harshest outdoor glare.

With TU3 you can choose between Chromatic or Guitar/Bass tuning modes, and enjoy visual pinpoint tuning verification with the Accu-Pitch Sign function. TU-3 even 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.

Boss TU-3 delivers the new-standard tuner that no guitarist or bass player should be without!
