Boss TU-3 Chromatic Tuner

The TU-3 maintains the robust BOSS stompbox structure, featuring a 21-segment LED meter that, along with the "High Brightness" function, allows you to tune your instrument in any low-light situation. You can choose between "Chromatic" or "Guitar/Bass" modes and visually check tuning accuracy with the "Accu-Pitch Sign" function. The TU-3 is equipped with a note name indicator that supports both 7-string guitars and 6-string electric basses, and in "Flat Tuning" mode, you can select the tuning type up to 6 semitones. The TU-3 is the essential stage tuner that no musician can do without!
