“ne of the representative models of KORG’s analog synthesizer is this MS-20.

The mini which became 80% size now is reprinted and sold, but this is the original model announced in 1978.

MS – 20 has a former type and latter type, this is the former type.

Although it is often described as a tone similar to MOOG, the greatest taste of MS – 20 is an intense filter that oscillates with unique distortion.

This will give you a dramatic change in timbre.” Click here to search for synths on eBay

“This auction is for my personal original vintage Korg MS-20 Semi Modular Synthesizer. It is a Mark I model with the Korg-35 filter design, known for it’s “ballsier” and more aggressive sounding filter section, vs the Mark II models.

This unit is 100% operational with no issues. It is in great cosmetic shape with some light minor scratches and wear-n-tear, which is to be expected on an instrument of this age.” Click here to search for synths on eBay

“Up for sale the amazing Korg MS 20 from the late 70s. Fully functional, in good cosmetic condition. All the buttons, patches and keys work as they should. I used this synth for overdriven leads, baslines, cosmic fx and somethimes ran samples trough the filter to add some character. I have played the new ms20 and it sounds too clean and the filter does not scream like older version but not to say the new one is a bad synth. That’s why I prefer the old ms 20. I’m selling it because I need to move out and need money to cover my bills. So take advantage to own the true iconic ms 20. It comes with the european plug and psu converter to be used in usa. ” Click here to search for synths on eBay

” Here’s a Vintage Korg MS-20, its the Mark I grey face filter which is a little bit rarer I believe. The filter is aggressive.
It was serviced in 2008 by LA synth tech “Synthfool” Kevin Lightner, RIP.
He rebuilt the Sample and Hold circuit, replaced a cracked key and the front panel jacks, and generally cleaned it up as well as tuned it.
It sounds good. But is in need of more tuning and cleaning.

I’ve included a video of me playing each key, and then running an arp via Midi to CV while tweaking the VCOs and filters. You’ll see in the video that certain keys ‘wobble’ in pitch. Also, notice the volume knob crackles with use, you might get some intermittent noise like that from the pots. I’m not a tech, but maybe this means the contacts need to be cleaned on it in general and especially the keyboard, it is after all 40 years old.

I’m listing it ‘for parts’ as there is no return and these issues are documented, but I’m assuming someone will clean and tune it and not strip it out for parts, which would be a ridiculous shame..”

“Original KORG MS-20 mfg. between 1978 and 1983. Made in Japan. Being sold as “parts not working” because there are some scratchy pots and I am not a good enough synthesis person to accurately test how this is supposed to sound. Here’s what I know: It powers up and when I open up the filters all the way it seems to sound like it should. Here is what I have been able to test as best I can and feel confident listing: All keys working with no sticky keys. Both VCOs work (waveform select, tuning, octave, mix) seem to work as should. Filters (1 high pass and 1 low pass) with peak (resonance) also seem to work as should. All the Envelope Generator stages seem to control ADSR as they should and the modulation generator (LFO) seems to work as should. Portamento too. What I am not sure about is the modulation wheel. When I patch out of the Mod Wheel CV out jack I can get it to work on by patching into one of the VCO in jacks changing the pitch of one of the VCOs (not sure which one) and it only bends up. I am not sure what the button below the mod wheel does and don’t know how to test it. Again, the main reason sold as parts-not-working is the scratchy pots issue and I am not sure how to program and really test all the patch points to know if it is working 100% properly. Please make sure you are OK with that before bidding. Feel free to ask questions and if there is something you want me to test I will be happy to do so and report back. A bit history on this… I purchased it in late 1993 and it has sat in my smoke-free office unused since. So it essentially not been powered up for the last 25 years. So in spite of the scratchy pots, is is a low-hours item. Since sold as Parts-Not Working there are no returns, no inspection periods. ” Click here to search for synths on eBay
