This is a YAMAHA MP-90 metronome. I am selling it because I have only used it a few times. It is in good working order and I have confirmed that it functions without any problems. The second photo shows everything that is included. There is no box. There is an instruction manual. When shipping, I will attach the stopper shown in the fourth photo. Please remove the stopper before using. Please understand that this is a used item and has been used by an individual. Please refrain from purchasing if you are looking for a perfect item or are overly concerned with details. Please do not make any offers for a price reduction. Immediate purchase is welcome.
