Boss TU-3S

The BOSS TU-3S is a chromatic tuner that brings world-class performance in a compact size. The TU-3 is one of the most famous stompbox tuners out there and the inspiration for this model. This version is smaller in size but otherwise functions the same. The display and tuning functions are identical to those of the TU-3

In addition, there are three modes, chromatic, guitar and bass, with which you can tune your instrument perfectly. Thanks to the visual Accu-Pitch function you can tune very accurately. The Flat-Tuning mode supports you in tuning up to six semitone steps.

When the pedal is engaged, the signal is automatically muted. Thanks to the optional PSA230 and loop cables you can power up to seven additional effects pedals. Truly a special tuner!
