Korg MS-20 Mk1 240v

An original Korg MS-20 Mk1 analog synthesizer for sale in excellent condition and perfect working order. This is the earlier version with the sought-after Korg 35 filter chip.

It has just been serviced, cleaned and calibrated by James Walker at Synth Repair Services: it sounds absolutely amazing and plays wonderfully.

The cosmetic condition is excellent overall with very few obvious signs of age. The main face presents superbly, but there are some minor scuffs and scratches as you’d expect (one calibration hole rubber grommet is missing). There’s more obvious signs of age to the front edge of the top and back, and of course the plastic sides have some marks/scratches. The metal case to the underside has more signs of oxidation and scratching as you’d expect. Click on the photos to zoom in and see more shots. The two waveform selector control knobs should be the larger size, but this machine came with smaller (original Korg) knobs fitted in these positions.

There are no known operational faults with this unit.

It’s a UK 240v model.
