Item number 2630005,
This high-quality metronome will help you keep a steady tempo while practicing or while performing. This super device features a tuning note (A440), an earphone jack (with the earphone included), a wide tempo range (40 to 208 beats per minute), a LED indicator (so you can turn off the sound, and SEE the tempo you've dialed in), and a convenient analog tempo selector (so you can change tempos FAST). This is a really nice digital quartz metronome, with all of the options installed. Highly recommended.
