Back in 1996, this Japanese gem emerged as one of the rarest takes on the legendary TB-303 sound, delivering that squelchy acid bass in a compact MIDI module form no one saw coming.
It's a fully analog monophonic beast with a single oscillator offering saw, square, and pulse width waveforms, feeding into a classic 303-style filter with cutoff, resonance, envelope mod, and decay controls up front. Tweak accent for punchy dynamics, volume, and power right there too, all on a half-rack chassis that's easy to rack up or desktop. MIDI in and thru handle note data, channel selection, and even aftertouch mapped to filter sweeps, plus a rear pitch knob for fine-tuning and a 15V AC power input—note that some units run best at 15V to avoid a dull tone.
Owners love its whistling resonance and burbling bass that drives step sequencers like a dream, often calling it a top contender among 303 clones for holding its own with smart extras like full MIDI without losing the raw analog soul. That occasional attack click? Just adds character to the self-oscillating fun.
