Boss TU-3S Chromatic Tuner, Compact Guitar and Bass Tuner Pedal with 21-segment LED Meter, Drop Tuning Support, and Guitar/Bass Mode.

A Compact Tuner for Your Pedalboard

The BOSS TU-3S chromatic tuner pedal takes everything you love about the popular TU-3 and scales it down in size by eliminating its pedal switch. Beyond that, you get the same rock-solid tuning and innovative features that you've come to expect from the TU-3, such as an easy-to-read LED display and various tuning modes. Chromatic mode is ideal for tuning by note name, while Guitar/Bass tunes by string number - even for 7-string guitars and 6-string basses. Guitar Flat mode is tailor-made for Drop tunings. Always on and ready to go, the BOSS TU-3S is a pedalboard necessity!
