Compact Chromatic Tuner
BOSS - TU-3S

WORLD-STANDARD PERFORMANCE IN A TINY FOOTPRINTThe BOSS TU-3 is industry standard stompbox tuner, trusted by players all around the world for its reliable operation and bulletproof durability. Scaled down in size, the TU-3S gives you the same industry-standard performance in a smaller footprint, saving valued pedalboard space. The display and tuning functions are identical to the TU-3—the only thing missing is the pedal switch, so it's on and ready to go, the TU-3S is perfect for use with pedal switching systems such as the BOSS ES-8 and ES-5, and ideal for any setup where space is valuable.
