The Boss TU-03 is a handy two in one device for your essential playing needs. Simply clip onto the headstock of your instrument and tune up, then get playing with the in-built metronome adjustable from 30 to 250 BPM.

Tuner

Offering extremely accurate tuning performance, the TU-03 can also sound the pitch through its speakers to use as reference for multiple players. Chromatic mode allows you to tune to any pitch while dedicated guitar, bass, ukulele and violin modes serve even quicker in tuning. 

Metronome

The metronome has the option to adjust the volume so you can just follow the beat on the clear LED screen. Eight patterns and 10 beat variations let you play along to different styles and time signatures.
