Roland MC-307 Groove Box

Inside, the sound architecture and sequencer is like the Roland MC-505.

Outside, it has been streamlined for "DJ" use and "live performance".

It's in great shape. I don't know the history of this machine, but it works great for me.

WHAT'S INCLUDED

• The Roland MC-307.
• A reprint of the first section of the "Quick Start" guide.
• A new power supply rated for this device. (1000mA)
