Korg MS-20

“Rare and original vintage 1970s KORG MS-20 Monophonic Synthesizer. UK 240v Serial No 140877.

This appears to be an early serial number and whilst there is a screw above the VCA graphic centre panel, there is no OTA filter ‘daughter’ board (see photos).

I believe this to have the Korg35 VCFs & not the OTA filter making it a Mark I. Either way, both Mk I & MK II MS-20s are epic.

Whilst untested, this in a good clean condition, it turns on & appears to function as intended but please NB this is a VINTAGE machine and is SOLD AS SEEN.

It has been stored indoors for the last 30 years. Inspection & testing are suggested & welcomed PRIOR to purchase as I CANNOT ACCEPT RETURNS. As with any vintage machine, this would benefit from a full service and is priced accordingly.” Click here to visit listing on eBay

“The fine item you are considering is a Vintage Korg MS-20 Synthesizer In Custom Rack No Keyboard. This cool vintage synth from Korg is the original MS-20 but someone has separated the main unit from the keyboard and mounted it in a custom wood cabinet. Note, I do not have a keyboard, only the unit as pictured. The power cord coming out of the unit has a Euro type plug with a U.S. type adapter on it, so I have no idea what type of power it’s set up to use, so I’m not going to try plugging it in for fear of damaging something. The unit looks to be in well cared for cosmetic condition, with no signs of damage, but since I have no way to test it, I’m selling it “as is” and as “parts not working”. Please see my photos to have a look at this nice item.” Click here to visit listing on eBay

“Vintage Korg MS20 mk1 with the sought after Korg 35 filter chips. 240v UK version and includes 10 patch cables. Excellent sounding semi modular synthesiser with filters that provide real bite and crunch in comparison to the later models. Everything has been fully tested and is in perfect working order. Some superficial markings to the case, but nothing significant and in line with its age. ” Click here to visit listing on eBay

“In very good condition and fully working, the keys are still quite white and springy, please study well pictures before purchase, doubt you’ll find one in better nick considering age.

This version is the Rev 2 i believe, with the less noisier bassier filter, it is not one of the reissues – it is the original.” Click here to visit listing on eBay

Korg MS-20 with Korg SQ-1

” original 1978 korg ms-20 original monophonic semi modular synth , this synth is in amazing condition first to see will buy just not getting used this is a real bit of synth history and is only going up in the value the condition of this is great for 40 years old this has not been gigged with and is really good condition

not getting used time to buy something new for the studio but this is a beast , used on so many classic records from funk to techno the ms-20 has many uses
this unit also comes with the sq-1 t(the sq-1 sequencer ) this is a remake of the famous sq-10 sequencer this is not from the 70’s and was released few years ago but will let you add notation from a computer via usb to your MS-20 so its very useful as well as 2 sets of cv and gates” Click here to visit listing on eBay

“I’ll start by saying, the new versions are def cool, but not even close in raw tone. The original is still the real deal. These are quirky, cool synths… the best of Japanese Filters for sure. Gritty, gnarly and more. Two OSCs of sweet tone. Notice there is no screw on the VCA section panel.. this is an original 35 filter version.. known to be much more aggressive in tone and much rarer than the latter filters : )

Ive had this for years, used it for years on albums and soundtrack work. It always sounded killer, always stable too. Had a tech go over it last year, he calibrated it, cleaned all the pots.. its all in great workable condition… but one thing to note.. there is some pitting / rust spots on the metal chassis as shown in pics. Only cosmetic, nothing more than that.. Its been like that for years. Just stating for full disclosure.” Click here to visit listing on eBay

“WOW! Very cool old school Korg MS20! Complete with manual! (Not in the best shape)

I honestly don’t know much about this unit, it has not really been used much in the past 20 or so years though I’ve tested all the keys and most of the controls and it seems to function just fine. However due to the age of it it’s being sold “as-is” ” Click here to visit listing on eBay

“I have for sale an original mark one MS20. This may look like a mark two (with a screw on the VCA diagram) but it is in fact a Mark 1, with the desired filter (this was verified by the local synth shop in Austin when it was serviced a year ago) This also comes with the classic Korg SQ1 sequencer which works great with its patch points!

Unfortunately times are tough and I have to sell but I’m hoping this will go to someone who appreciates its beauty as much as I do!” Click here to visit listing on eBay

“The original version of Korg’s MS-20 Monophonic Analogue Synthesizer (not the re-issue). This one is in good shape, having been fully serviced for sale. Lots of re-capping, pot and key cleaning etc. It sounds lovely and to be honest i would really rather not sell it but i have next to no spare room at the moment so it has to go to give me a some more much needed space.” Click here to search for synths on eBay

“Rare to find an original MS20 (this is not reissue kit from a few years back or the MS20 mini). It really is really good condition with little rust on one of the EG 1 Trigger input that you can see in the picture but has not effect on usability. Also two of the knobs are been changed, again no effect on playability. I bought it in Brighton from a seller on Ebay that sold it to me working but in dusty condition, this caused some problems with playability, it has recently been fixed about a month ago by the great guys from the Southend Electronic Music Service to full working order. Selling to raise funds for other music equipment that is more suited to my set-up. The middle A key has a little chip on it and is a little bit marked.

Ive had this for years, used it for years on albums and soundtrack work. It always sounded killer, always stable too. I have never been one to do the modular/patching thing so that portion of this synth was never utilized.. I’m not that kinda guy : ) plus with as sweet as the standard portion of this synth is, i never felt the need to delve into patching. Couple of cosmetic things to note… there is a small crack on the right side panel.. never bothered me.. and the lowest white key on left is slightly tilted to the right. it still works/triggers fine, that never bothered me either.. been using it that way for quite a while.” Click here to search for synths on eBay

” Vintage, and original Korg MS-20 is good condition. No signs of physical or psychological abuse, no dings or huge dents or bruises to speak of (see pictures). I’ve owned it for a while now, but because of the pandemic there’s not much work out there these days… but the bills keep appearing every month- if you know what I mean… Sadly this MS-20 has been sitting idle for a few months now too…
This is a model intended for the USA market (you don’t need a step up or step down transformer). You don’t have to think about proper power. All of the knobs are present, all keys are good and overall it’s a pretty clean unit given its age. I used it mainly for recording sound effects and experimentation using the pitch to voltage converter, which produces interesting results to say the least! As you know, the LP and HP filters are gnarly! A few of the pots are a little noisy, some of the jacks can be cleaned, but that’s an easy fix. I hope it finds a good home because it’s been a trusty, loyal synthesizer with an abundance of sonic capabilities. Thanks and good luck, be safe and stay creative during these tough times!” Click here to search for synths on eBay

” KORG MS-20 Vintage Analog Semi-Modular Synthesizer – 1978 near mint. Condition is Used but look at the condition of this baby. Never gigged, only used for a few times in a studio. This one has the original and rare filter (the screw on the VCA stage holds the daughter board). It has never been opened or messed with – it’s 100% original. Also comes with manual and some patch cables.” Click here to search for synths on eBay

“This is an original late 70’s Korg MS20 Mk1 with the Korg-35 Filter chip.

The condition is exceptional for its age. Every aspect of the synth is fully working. There are a few very small marks on the top of the unit but the face plate is more or less blemish free. All of the keys are free from marks, fully aligned and responsive. All original knobs etc. Tuning is stable and tracks very well on both Osc’s.

This is also a UK 240v model so no voltage convertors are needed.”

“Studio use only in amazing shape with original manual! Sounds amazing!

A couple of the pots could probably use a little cleaning but otherwise great! It’s a vintage synth…

If interested I’m happy to send a video link for a demo of the synth.”

“Original vintage MS-20 – the timeless, semi-modular monosynth.

Korg’s MS-20 monophonic synthesizer, first introduced in 1978, is still a coveted instrument to this day, thanks to its thick, robust sound, its powerful, iconic analog filter, and its versatile patching options.

Not looking to get big bucks for this Synth because of the cosmetics.

I have owned it for about 30 years. If you want the original sound it is here for you.

Bought this in 1980 – 81? SN – 145663

It was on the road so cosmetically has scratches, a missing volume knob and 2 minor cracked keys but it works!

I haven’t fired it up on stage since 1997. ”
