With its advanced V-Drums technology and wide variety of sounds, the RMP-12 offers enhanced playability, expressiveness, and versatility. It's perfect for indoor and outdoor performance as well as for quiet practice. Unlike other practice pads, the RMP-12 offers an amazing replication of acoustic drums thanks to its realistic sounds and feel.
