The Yamaha MS45DR is a new electronic drum amp for 2019. It is a small lower power system designed for personal use. Probably not going to be a stage solution at this small of a power rating. It is a 2.1 setup so you will get stereo on the satellites which mount on the rack and some low frequencies from the subwoofer. We have an MS45DR on order and when it arrives we will test it out. If you want to order one go ahead or let us know and we will put you on a waiting list to be notified once they start shipping. Shipping is supposed to start in July 2019.
