Korg MS-20

“This vintage Korg MS20 keyboard synthesizer, originally released in 1978, is a classic piece of retro equipment that any musician would love to have in their collection. With its semi-modular design, it offers endless possibilities for creating unique and original sounds. It is an excellent addition to any studio or live performance setup, and is sure to provide countless hours of creative inspiration.

This one comes in excellent condition, believed to be fully operational, but I haven’t tested every single parameter so this is not a guarantee! All keys and knobs are working as expected though and all insert points look clean. Serial number is below 150k which indicates that this is the Mk1 model with the better filter. Sold as is, so strictly no returns!! Buyer welcome to test fully on colection.

It’s fitted with a Japanese power cord requires a step converter to run from UK mains supply (NOT INCLUDED) AirLink trasnformers are recommended by SoundGas and are particularly reliable unlike some of the cheaper Chinese transformers, which I would never trust with one of my vintage synths!!!”

“It has been sitting in the studio for a while now used only occasionally since I bought it. It is a shame for this classic not to be used on a regular basis so looking for a new home.

It is in good working order, all keys work as they should (no double notes when pressed), all pots working. There are some marks on the face and back and slight rust as shown. One of the end cheeks has some discolouring (like this when i bought it).

happy to accept reasonable offers” Click here to visit listing on eBay

“In this auction, I’m selling my original Korg MS20 vintage semi-modular analog synthesizer.

There is probably not too much to tell about the legendary Korg MS20 series. There have been quite a bunch of remakes of this synth but I can tell you that the original version from the 70s-80s just sounds more grittier, dirtier, and meaner than all the remakes made. I’ve tried many of the newer versions and it’s just simply not the same. With the old version you get the authentic sound: The little rattles and electric hisses when turning the knobs, and the screaming resonances when cranking up the resonance (peak) – which are all part of the unique sound of this synthesizer gem. With this synth, you can create screaming Lead Sounds, Growling Sub-Basses, or either massive or thin Pad sounds. With the analog patch bay, your possibilities are countless.

I’m selling this Synth because I’m moving and I just simply don’t find the time anymore to play with my analog gear.

The Power supply/plug for this MS20 is European (220V), but I’ve included in this auction the power converter to make it work with 110V any other voltages.

I’ve used this Synth before with a Korg SQ-1 as a sequencer and with a little fine-tuning it worked great in combination.

The condition of this synth is used, it has little cosmetic signs of use (see pictures). When turning the knobs you hear little hisses sometimes (which is part of the original sound). I’ve connected the synth to my DAW before making this auction and all functions (as far as I was able to test them) worked. Since this is a vintage Synth, with endless combinations, I can only sell it as is, without being able to test every single possible connection and routing.

This auction includes:
– Korg MS20
– Power Converter
– 4 Patch-Cables
– 2 Patch cables (3.5mm to 1/4″)
– Original Manual” Click here to visit listing on eBay

“I’ll start by saying, the new versions are ok, 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.

It all works and sounds great. In tune etc but may need a tuning after transit to you. Noting out of the norm.

Solid synth for any studio or stage.” Click here to visit listing on eBay

“This Korg MS20 Monophonic Synthesizer circa 1980 is in good cosmetic with a fair amount of scratches on the back and bottom of the chassis, and some very small scratches on the main faceplate. The master volume knob has been replaced with a non-matching knob, and the initials “SFA” painted on the bottom. It is fully functional and sounds fantastic. All of the potentiometers are clean and all of the keys are set properly and work as good as new.” Click here to visit listing on eBay

“Up for sale is a Korg MS20 ORIGINAL VINTAGE synthesiser. Made in Japan – Serial 149563

I had it in storage for years and clearing out my equipments as no longer in the music scene.

There are slight cosmetic scuff marks on top panel which existed when i first bought it.

All keys are working and a few turned slight yellow but doesn’t affect the performance. I have removed the two side panels, all seemed fine. Included in this sale are a bunch of 6 short cables as seen in photo. ” Click here to visit listing on eBay

“This Korg synthesizer is in pretty good condition for it’s age. There are some small scuffs and scratches on the control panel (largest is on the far left side), but I’d consider this all to be minor. There’s also one screw missing from the front panel (top left). I tested the unit using a pair of headphones. The synthesizer seems responsive as I turn/adjust various controls. I am by no means an expert on synthesizers (or a musician of any kind for that matter), but it does seem to be working properly. Some of the controls are a little scratchy and this can be taken care by spraying them with electrical contact cleaner and turning the knob back and forth. This is really common on old electronics of any kind, and you can buy a can on eBay or Amazon for $10-15.”

“This is the original vintage version of one of the all time greatest analogue synthesisers. This particular synth is a Japanese import so runs off 100v. (see note at bottom)

This is in really good cosmetic condition with no major scratches and even includes the original Japanese plastic covering overlay. It plays very well but there are a couple of slightly scratchy pots as can be expected.

I can’t say this is definitely the easiest filter version without opening it up but it doesn’t have the front screw panel like most vintage ones do.” Click here to visit listing on eBay

” Korg MS-20 Vintage Synthesizer. This original model, known for its plethora of analog synth sounds, was originally released in 1978 and in production until 1983. At the time it was a prime machine for many artists and bands making music in the realms of industrial, EBM and minimal synth. I purchased this from a musician who said it was used by the band Orchestral Manoeuvres in the Dark (OMD) on their song Enola Gay.

The wheel no longer works and there are scratches,blemishes on the body and keys but the synth works perfectly and sounds amazing!
It is sold as is.” Click here to visit listing on eBay

“Wonderful synth in great condition as can be seen in pics. Full working order. Was given a service when in the hands of the previous owner which is when the back plate sadly went missing.

I’ve had this for several years now and although it really does sound fantastic I rarely use it as I primarily source all my sounds from acoustic instruments. The bass is something else though, and not to be imitated or replaced… people always comment on the bass when used in recordings. The inherent noise adds so much texture and warmth, something you cant get on newer synths, not to this extent anyway.

I have some patch cables I will include and a copy of the manual.” Click here to visit listing on eBay

Spent most of its existence (25 years) in an attic where it succumbed to some rusting. Some pitting and scratches. More minor blemishes on control area, and depending on angle of view – as shown in more detailed photos.

The synth has been cleaned thoroughly but not serviced and works on UK mains.” Click here to visit listing on eBay

“Korg MS-20 Original Vintage Semi Modular Analogue Monophonic Synthesizer. One Owner From New. Serviced & Tested

Up for sale is my Korg MS-20 Synthesizer, Serial Number: 147765, which I bought brand new, together with a Korg SQ-10 Analogue Sequencer, on the 11th of June 1983.

It has never been gigged, having had a productive working life in my recording studio during the late 80s and 90s and has been in safe storage for the last few years.

It has recently been professionally serviced and also has a current PAT Test.

It’s in excellent vintage condition and good working order with some minor signs of age and use – please see pictures.

Plays and sounds great.

NB. It is missing one screw from the left side panel, which I only noticed during the photo shoot for this listing.

Also included are the Owner’s Manual & Setting Examples Manual which are both incomplete, annotated and tatty, but hey!!!”

“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”.
