WORLD-STANDARD PERFORMANCE
BOSS The TU-3 is the world's most popular stompbox tuner, used by musicians everywhere for its reliable operation and rock-solid quality. The TU-3S is scaled down in size but gives you industry-standard performance that saves you precious space on your pedalboard. The display and tuning functions are identical to the TU-3 - the only thing omitted is the pedal switch. Always on and always ready, the TU-3 is perfect for use with pedal switching systems like BOSS ES-8 and ES-5 and ideal in any setup where space is at a premium.
