There is a constant hum while the unit is on. When actually using it, the hum is not quite as noticeable but it' still there.

I've included a video. I've turned the unit on and off a few times so the hum should be heard.

The top half of the plastic has yellowing. The bottom half is not as bad.

The keys have a good amount of wear as seen. 

Includes everything shown in the first picture.

May be shipped USPS, Fedex or UPS.

Due to it's issue, this Omnichord is being sold as-is for parts or repair. 

No returns.
