Works and looks good. Has some scuffs and scrapes. Battery compartment had some old dried battery leakage. But, I cleaned it off as best as I could. Battery ribbon is gone. Now, it's very clean inside and out.

Includes Omnichord System Two Model OM-84 Operation Manual and an original box with top and bottom styrofoam pieces. The serial number on the box does not match the one on the unit. The box has pen marks, tears and stains.

I will include a compatible AC adapter for USA/Canada buyers only. Batteries not included.

I will put the box inside an outer shipping box to protect it.

See pictures.

This is the best-sounding Omnichord (including the QChord) in my opinion.


  • 84 chords (12 keys x 7 variations: major (top row buttons), minor (middle row), (minor) 7th (eg. C7) (bottom row), major 7th (eg Cmaj7th) (top + 
bottom), minor 7 (eg. Cm7) (middle + bottom), diminished (eg. Cdim) (top + middle) and aug 5th (all three buttons))
  • 10 punchy, preset 
analog drum patterns with optional auto chord and bass accompaniment
  • "SonicStrings" voice has a magical shimmer
  • Manual chord memory sequencer
  • Built-in speaker
  • You can use the darker buttons as a basic monophonic keyboard as you toggle through the chords you programmed previously
  • 1/4" output jack
  • Runs on 8 "C" batteries or 12V negative (-) tip AC adapter (tested and works on both)
