Back in 1973, this little wooden cube kicked off Roland's iconic drum machine era, bridging the gap between basic rhythm boxes and the legendary CR-78 with its fresh analog punch and that unmistakable boxy charm.
Inside, eight transistor-based analog voices deliver classic sounds like a beefy kick drum—often compared to an early 808 for its deep girth—hi-hats, snare, toms, claves, cowbell, conga, and guiro, all shaped by a lowpass filter, self-oscillation, and overdrive for gritty edge. A single Balance knob is genius: twist clockwise to kill the kick and spotlight hats and snare, or counterclockwise to mute hats and let the bass thump solo, while volume, tempo slider (from ambient crawl to grindcore blast), and swing/metronome switches handle the groove across 10 presets like Waltz, Bossa Nova, Mambo, Cha-Cha, Rumba, March, Slow Rock, Rock Beat, Beguine, and Swing. It's monophonic with a 10-pattern sequencer, built-in amp driving a loud, bassy speaker perfect for band practice, plus mono 1/4" out and footswitch jack; measures a compact 9.5" x 12" x 7" at 10.5 lbs.
Vintage hunters love its modern-sounding beats that hold up today, though the speaker adds a cheesy distortion some embrace as character—mods unlock even more tweaks if you're handy.
