"'King Beat' Rhythm-Matic R2000 Drum Machine Vintage - Wood Finish. Likely distributed through Sears. Fully functional with a killer sound. Interesting low end that sounds killer distorted and smashed with compression. All patterns work with consistent tempo. The metronome sounds like a bass drum which is useful. Fun and straightforward machine."
