The BOSS TU-3 is the world's must-have pedal tuner, trusted by players around the world for its reliable operation and bulletproof durability. Small in size, the TU-3S gives you the same industry-standard performance in a smaller footprint that saves valuable pedal board space. The display and tuning functions are identical to the TU-3 - the only thing eliminated is the footswitch. Always on and ready to go, the TU-3S is perfect for use with pedal switching systems like the BOSS ES-8 and ES-5, and ideal for any setup where space is limited
