BOSS DB-30 Dr. Beat Metronome

THE TAKE-ALONG DR. BEAT

It’s portable, reliable, and fun to use — the DB-30 helps musicians take their music to higher levels by offering a set of features that defies its diminutive size. Much more than just a simple timekeeper, this pocket-sized metronome can lay down a variety of rhythm patterns and time feels to practice along with, and it has a few timekeeping tricks up its sleeve as well.
