Korg Sigma KP-30 Vintage Multitimbral Monophonic Synthesizer SN 241659
via this auction
"Great working condition vintage Korg Sigma KP-30 from 1979... that's a 37 year old vintage synthesizer and only 1000 units were ever made. This is when Korg was still repping the Keio Electronic Labratory Corp. and made all their synths in Japan. Very high quality build has been near maintenance free for the last 20 years with just a professional deoxit tune-up every other year or so."
