Practice in style with the flagship of the Dr. Beat Metronome line! The new DB-90 is loaded with quality sounds and drum patterns to make your practice sessions less mundane and more musical. Included is a Rhythm Coach function with an onboard mic, a reference-tone function for tuning, an Instrument input, MIDI input, and other handy tools to make learning fun and effective. Static cling protection covers the display. I am selling this at discount because the box is damaged. What you get: Protective Cover User Manual New Energizer 9V Battery
