Korg MS-20 - Mark 1

Very good example of an original Korg MS-20 analog synthesizer. This is the Mark 1 / Korg 35 chip version which some prefer – more aggressive at higher resonance settings.

Serviced, cleaned and calibrated by a top synth tech: it sounds great and plays wonderfully.

In very good condition for its age. Has some small marks and dings to the case but very few on the face itself. It is missing the rubber grommets from the front calibration holes. Click on the photos to zoom in.

For sales in UK/EU the price will include VAT. VAT-free sales are possible to businesses and individuals in the EU (outside the UK) with a valid VAT Number – please get in touch if you wish to buy this way. 

• It is a 100v Japanese model and will run fine on North American mains 115/120v without a transformer (we run all our tests using 120v power); however, a step-down transformer is recommended for extended use.
• A step-down transformer is required in the UK/EU.
• We do not recommend using cheap generic Chinese mains transformers and can supply a high quality UK-made unit if required
