BOSS TU-3S Chromatic Tuner
WORLD-STANDARD PERFORMANCE IN A TINY FOOTPRINT
The BOSS TU-3 is the world’s go-to stompbox tuner, trusted by players everywhere for its reliable operation and bulletproof durability. Scaled down in size, the TU-3S gives you the same industry-standard performance in a tiny footprint that saves precious pedalboard space. The display and tuning functions are identical to the TU-3—the only thing eliminated is the pedal switch.
