TU-3 Tuner

The BOSS TU-3 Chromatic Tuner is an industry-standard pedal tuner, first introduced in 2009, offering high-precision tuning and rugged reliability for guitarists and bassists. With its bright LED display, 21-segment meter, and high-visibility mode, the TU-3 ensures accurate tuning on dark stages and in any lighting condition. Featuring true bypass and a built-in power output for daisy-chaining other pedals, the TU-3 is a must-have for professional and gigging musicians. Known for its rock-solid build and precise performance, it has become the go-to tuner pedal for countless players worldwide.
