Boss TU-3S Chromatic Tuner

The Boss TU-3S Chromatic Tuner is a condensed version of the Boss TU-3 tuner pedal omitting the footswitch mechanism but still featuring all of the same internal components. The Boss TU-3 is arguably the most popular tuner on the planet for its simple functionality, roadworthy build, tuning accuracy and readable displays.

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 at a premium.
