BOSS TU-02 Clip On Chromatic Tuner

With a bright colour display, swivel adjustment, and four selectable modes, the versatile TU-02 offers reliable tuning for guitar, bass, ukulele, and other stringed instruments. With its versatile modes and quick-change design, you can tune a variety of instruments with the TU-02.
