Boss TU-3 Chromatic Tuner Pedal


The BOSS TU-3 Chromatic Tuner continues the BOSS legacy of a flagship stomp-box style guitar tuner, found in pedal boards around the world. Extremely accurate - the TU-3 is capable of measurements +/- 1 cent. New features found on the TU-3 include an ultra bright display mode for live shows, and both a 21 segment LED VU and strobe style visualisation modes.
