Back in 1981, this compact analog beast turned any guitar into a snarling monosynth without needing fancy pickups—just plug in and let its built-in pitch-to-voltage converter do the magic, pulling from Korg's MS-series tech.
It's a desktop unit with 16 hands-on knobs and 12 colorful pads for instant access, packing a single VCO with pulse, square, and sawtooth waves in the Synthe section, plus lowpass VCF, two envelopes (ADA for amp, AD for filter), and built-in distortion for grit. Six preset patches include: Electric Bass, Tuba, Trumpet, Dist. Guitar, Violin, Flute. You can stack or switch voices, with velocity sensitivity and controls for mix, sensitivity (-20/-35/-50dB), and portamento. Rear panel brims with CV/Gate (Hz/V and 1V/oct), Trigger I/O, FM in, VCF mod in, dry out, and footswitch jacks for tracking, hold, and bypass.
Synth heads cherish its raw, organic dirt sound (think TB-303 acid but "crack" filthy), making it perfect for processing drums, vocals, or lines. Vintage quirks like no LFO, MIDI, or resonance get overlooked for that unpredictable edge; serviced units still wow today.
