What it is
The Korg MS-20, released in 1978, is a semi-modular monophonic analog synth beloved for its aggressive, gritty character and its hands-on patch panel. Two oscillators, two distinctive filters (a high-pass and a low-pass that can scream into self-oscillation), and a small but flexible patchbay make it a favorite for basses, leads, effects, and noise. Korg has kept the design alive with the full-size MS-20 Mini, the MS-20 FS reissue, and kit versions, so the name now spans vintage and modern hardware.
Buying one used — what to check
The first thing to pin down is which MS-20 a listing actually is: an original 1978 to 1983 unit, the smaller MS-20 Mini reissue, the full-size MS-20 FS, or a Behringer clone — they share DNA but differ in size, connectors, and value, and titles are often vague. Original units use one of two filter revisions that sound subtly different, worth noting if tone is your priority. On any vintage unit, check the patch jacks, the sliders and switches, the keyboard contacts, and confirm both filters self-oscillate cleanly; the original's non-standard mini-jack patch points are also worth verifying. Ask about servicing on older units.
Regional sourcing notes
Korg is Japanese, so the MS-20 in all its forms is well-represented in Japan — vintage originals and the reissues both turn up on Yahoo Auctions and Mercari, often at good prices. Domestic units are 100V and want a transformer abroad. In Japanese listings look for コルグ (Korg) and MS-20, and read the condition terms — 動作確認済み (tested working), 整備済み (serviced), 美品 (excellent), against ジャンク (junk) and 未確認 (untested). Because vintage and reissue MS-20s are described in overlapping ways, a careful cross-market look pays off — Brrtz scans Japanese and Western sources together so you can tell an original from a reissue and compare prices in one pass.
