This sale is for a fully functioning Omnichord OM-84 with original soft carrying bag. Nothing else is included, you will need a 12VDC 500ma negative polarity power supply or 8C batteries to power it on. Please refer to the pics for physical description of each item. The bag has a bit of some writing in the back as seen in the pics, but it zips up and protects the Omnichord just fine. The Omnichord shows signs of wear consistent with normal use. There was some corrosion from a batteries that were left in the battery compartment too long. I cleaned up the springs as best as they could be and replaced one circuit board that had been damaged. You can see the battery springs in the pics as well. I am also including a short video of the Omnichord being played. If you have any questions, feel free to ask. Thanks for looking!
