The Tama Rhythm Watch is the first metronome to give drummers the special features they require. And it has enough volume so you can play with real drums.
The large display is easy to read during performance, and there's a large dial for quick tempo adjustments. Choose from 2 different sounds. 20 different memory settings can be recalled instantly. Red and green LEDs offer visual reinforcement. Volumes for quarter notes, eighth notes, and triplets can be set individually for different rhythm patterns. Tap function lets you find the tempo by simply tapping the START/TAP button.
