“Korg’s version of an FM synth , easier to operate than yamaha FM but less complex also.
Includes rare memory card
Sounds great and can be smooth or noisy & rough , similar to dx100 in terms of aliasing and good bass sounds.
Has quick edit sliders for envelopes and timbre so you can tweak as you play.
49 keys with velocity and mono aftertouch. Pitch and mod wheels.
It has been circuit bent with 8 switches on the data lines to make some weird noises.
This sometimes corrupts patches but all patches can be backed up and restored from the memory card.
A few scratches but no cracks in the case, buttons all work. See images . Sounds good, but I have to many FM synths.”

“An original korg-ms20 in good condition. Kept in a smoke and dust free studio, the item has never been gigged by me in 4 years of ownership.
“Selling my very special and rare Korg 770. This synth is in incredible condition for 42 years old. Cosmetically it has some signs of wear and a hand full of the original knobs have been replaced as you can see in the photos. Everything works. Not only does everything work, I have also retrofitted the synth with a Kenton CV kit so there is cv control over Hz/V, gate, and filter. Sequencing this machines notes and filter is INSANE. You can integrate this with an analog sequencer or kenton midi to cv box (or any other cv source even a korg sq-1). Last year I also had Rosen Sound in Los Angeles install a midiplant so not only can you control the synth via cv, you can also trigger notes via the midi port on the back with a quick flip of a rear toggle switch. I personally still prefer the control and resolution of straight cv. The synth is really incredible and I’ve sampled more sounds from it than any other instrument I own. Have a listen to some demos on youtube if you aren’t familiar. This machine is from another planet. The serial number is 770073 and it was one of the first units produced. Extremely rare and hard to come by for good reason. Also including a custom made dust cover.
“Previously owned. For parts or repair. Power supply not included”
“Used. Only put in a rack once or twice. Works excellent and a joy to play.”

“The synth part can create some nice bleeps and bouncy basses while the strings section is perfect for recreating THAT classic 80s string sound.
“I was given this by an old gearhead who worked with Blur.
“We are selling a KORG DW8000 Keyboard that was taken in on trade, and played good, but when we turned it back on to play, it played a couple of sounds. Was not tested any further. If you know how to get past this, then our loss is your gain. Sold As-Is.”
“Original 1978 Korg MS-20 Synthesizer in excellent working condition.
“FS: Clean #Korg #Poly61. 3&4 numeric buttons double-press at times but totally work (replacing tact switches of all numerics would be wise at some point). Also, 1 or 2 keys need their contacts reseated/cleaned. Again, all work but I’m a very discerning seller who strives for maximum accuracy. If you’re wanting an 80’s 2 DCO polysynth with a lush sound akin to the Juno 6/60 and has an arpeggiator w/ arp input for stepping via a trigger/gate and doesn’t break the bank, this is it. ”

“Selling my Korg MS-2000R digital synth (which is the same as the MS2000 but without the keyboard, and it has the same synth capabilities as the Microkorg but with easier access to all parameters through knobs and not menu diving).

“Used Korg MS2000R rack synth
” Surface rust on some jacks. The assignable button is missing but everything else works fine.” 
“Just Serviced with new backup battery .. all working as it should .
” I am rather sadly selling my beloved Korg Polysix. This is a genuine analogue synth, first manufactured in the early 80s. I bought this particular Polysix from a friend back in the early 90s, and I believe this friend purchased it new. Over the last 25 years I have enjoyed playing this synth in a number of different musical ventures and styles, but now demands of space and cash mean I need to put it up for sale.
“This was working well until recently when it wouldn’t turn on anymore. I’m not sure what the issue is but it could be an easy fix. Comes with the rack ears (which are often difficult to find). Also missing one of the plastic feet from the bottom (these are easily replaced).” 
“I bought this a couple of years ago for a number of projects and just fell in love with its incredible sound (so so warm – think Boards of Canada for a simple idea). I bought it in the same condition (with the same sticker) for a significant amount of money as they are quite hard to find. It had just had its electronics cleaned out and tested (hence the rather annoyingly glued modulation wheel area – see pix). It has some marks here and there but plays beautifully – remarkable for these synths given their age. It has never been toured and only kept in studio. When not used for recording this was always covered and protected carefully. ”
“I bought this from a collector who basically stored vintage synths and kept them in museum condition for years. I paid significantly more for this two years ago than is the average going price due to the amazing condition (see pix). The only marks it has are due to age but I’ve never seen one with all original parts in such great condition. It has never been toured and only kept in studio. When not used for recording this was always covered and protected carefully. It thus comes in truly amazing condition (all original which is very rare). It comes with the original 1982 manual and I will also include one of my large super secure hard Gator cases (with wheels). Just a note that the Gator case itself is well used (see pix) but is perfect for housing and looking after this synth.”
“Keyboard in good working condition, minimal wear and tear. No manual or any other accessories included. See pictures for condition.”
“Korg ms2000 synthesizer.This is in good condition,it has a few light marks (looks like where tape was stuck) the wood has a slight mark on one end and 2 knobs missing from sequencer otherwise good.It plays fine and everything works as it should- wheels,sequencer,audio in.It is a fantastic little synth and the sequencer is great fun and easy to get lost just tinkering about.It has a great range of sounds-nice pads/strings/fx great bass and lead sounds and easy to program and make new patches,No manual,comes with mains lead,midi lead and 2 instrument leads (jack).”
” 1983 Korg Poly 61 home use only never gigged I’ve owned it from new, works fine. cosmetic damage to C key one octave down from top,(see photo) replacements are about £6 off e-bay. I’ve lost the manual but it is self explanatory parameters are printed on the top as you can see, so you type in the parameter number and adjust as you key the sound, simples. Collect only please.”
