Vintage Omnichord OM-200 Comes with instructions, 12V car adapter.
Tested and works.
Does not come with AC adapter (can be bought online)- comes with a 12V car plug in.
Battery compartment has corrosion
It does work with batteries, for some reason Energizer C batteries did NOT fit, but my Dollar Store batteries did
No box, just styrofoam
Local pick up possible, Saint Paul, MN
