Vintage Korg Mono/Poly analog synthesizer, purchased new and owned by a single owner since 1983.

This is a very clean, well-preserved example of one of Korg’s most distinctive analog synths—known for its unique 4‑oscillator architecture, chord memory, and powerful arpeggiator. Capable of everything from classic mono leads and basses to complex rhythmic textures and pseudo‑polyphonic sounds.

Condition:

  • Front panel, sides, and rear are exceptionally clean for its age
  • Bottom panel has some scratches from keyboard stand use (purely cosmetic)
  • Volume potentiometer is scratchy and would benefit from cleaning
  • All other controls are functioning properly and respond well

Functionality:

  • Fully tested
  • All oscillators, filters, envelopes, and modulation functioning as expected
  • Arpeggiator and chord memory working

Please see the included demo video for a direct example of the instrument in use.

This is a great opportunity to own a clean, original-owner Mono/Poly that’s been well cared for over the decades—an increasingly desirable analog classic.

Ships carefully packed, or local pickup available.
