MR500
An economical quartz metronome with an easy-to-use dial speed control, the MR500 is a popular choice for many students. Quickly select any tempo from 40 to 208 beats per minute, or produce a reference pitch of A-440. Tempo is heard as an almost wooden "tock" sound, and is also shown in a flashing LED. Comes with an earphone for those times when it's hard to hear. Takes 1 9V battery (not included.)
