Back in 1986, this pocket-sized powerhouse brought realistic acoustic drum sounds to bedroom producers who needed beats on a budget, standing out in Boss's Dr. Rhythm lineup for its gritty 12-bit PCM samples that pack real punch despite the era's tech limits.
Super compact at just 239 x 75 x 31 mm and 350g, it slips easily into a gig bag and runs on four AA batteries or AC adapter, with a front-panel volume slider integrated right into the case design. You'll find 11 acoustic voices like punchy kicks, crisp snares, and toms, played via a 4x3 grid of non-velocity-sensitive pads next to a simple LCD that shows one step at a time—up to 16 steps in 4/4 or 12 in 3/4 mode. Program 32 user patterns via step entry or real-time tap recording, tweak accent and volume (0-5) per voice, chain them into eight songs up to 128 bars each (or 256 via song chain), and dial tempo from 40-250 bpm. Rear panel keeps it straightforward: 1/4" mono out, 1/8" headphone jack, and trigger I/O for 5V pulse sync with other gear—no MIDI, but dead simple for the time.
Folks digging vintage gear love its raw, hissy character that's perfect for lo-fi tracks or sampling, though some note the channel-sharing quirks mean not all sounds hit together, like limiting to one tom per beat. It's a no-frills survivor that still inspires jams today.
