BOSS TU-03 Tuner

The BOSS TU-03 is a versatile clip-on device that combines two essential tools for musicians: a chromatic tuner and a metronome, all in a compact, user-friendly design. It clips securely to the headstock of nearly any stringed instrument, offering quick access to accurate tuning and rhythm support whether you're practicing at home or playing live.

With five tuning modes including chromatic, guitar, bass, violin, and ukulele C, as well as adjustable reference pitch and flat tuning options, the TU-03 is built to accommodate a wide range of instruments and styles. Its integrated metronome features a built-in speaker, a wide tempo range from 30 to 250 BPM, and eight rhythm patterns, giving you flexible timing control wherever you go.
