Roland's V-Drums are the most popular electronic drums in the world, but not everyone has the room or budget for a full V-Drums kit. Introducing the new Roland HD-1. It's forged from the same technology as its predecessors, but it's much simpler to use. It's also incredibly quiet, thanks to the newly designed kick beater, cushioned tom pads, and snare head. The HD-1 is also conveniently compact and stylish ? perfect for every home, school, studio, etc. ? and it's priced for the masses. Most of the HD-1's components are mounted on one stand for easy setup and transport, and for a clean look. Just take it out of the box and play. It might look small, but the HD-1 sounds and performs impressively large. With Roland's legendary V-Drum know-how at the core, this little kit is a dream for first-timer or casual players as well as for parents, since the volume level can be completely controlled via volume knob and/or headphones. The HD-1 is equipped with an external input for connecting CD-players, iPods, and the like. Jam along with your favorite songs, and control the blend of music and your live drumming through headphones or an amplifier. The HD-1 is a great way to enhance musical expression and enjoyment in your home. Used along with other popular instruments such as Roland's digital pianos, the HD-1 will serve as the nucleus for family fun and musical enrichment.
