The Tama RW30 Rhythm Watch Mini Metronome has all of the power of the original Rhythm Watch, but it's small enough to fit in your pants pocket or small stick bag.
The large stop/start button and tempo dial make basic controls simple, or you can tap in whatever tempo you'd like on a special tap button.
You can choose between high or low clicks for your personal sound preference, and you can modify the time signature to contain up to 9 beats. There are 6 rhythmic patterns available no matter what time signature you choose.
A clip holder on the back allows you to attach the microphone directly to your person, leaving your hands completely free for instruction.
