The performance of a reference material in a tiny case
The BOSS TU-3 is the unmatched tuner in pedal format, adopted by musicians around the world for its reliable operation and uncompromising resistance. Its reduced version, the TU-3S, offers you the same performance by allowing you to save space on your pedalboard. The display and tuning functions are identical to what is found on the TU-3; we simply removed the footswitch. Always ready, easy to transport, the TU-3S is perfect for pedal switch systems like the BOSS ES-8 and ES-5, and is ideal for any configuration where centimeters are counted.
