Boss Chromatic Tuner TU-3S barrel

WORLD PERFORMANCE WITHIN COMPACT DIMENSIONS

The BOSS TU-3 is the world's most popular stompbox tuner. It is used and praised by musicians for its reliable results and unbreakable durability. The TU-3S is smaller in size but provides the same performance and industry standard. It is made to save valuable space in your pedalboard. The display and tuning functions are identical to those of the TU-3. Only the pedal switch was eliminated. The TU-3S is always on and is designed to be used with switching systems such as the BOSS ES-8 and ES-5. It is perfectly suited for setups where space (saving) is important.
