This pocket-sized metronome features a Tempo Tap function for counting beats (measuring speed of your records for mixing). Simply tap the button to the beat of your song, and the MA-30 will give you an approximate beats per minute (you might have to do some averaging in your head). Resident BPM nerd and club dj K-Lim swears by this thing. The metronome portion of MA-30 is quite advanced for this small package with adjustable volume audio cues and adjustable rhythms and tempos. Also includes earphone jack.
