WORKING CONDITION: Fair - Mostly works and sounds incredible. When a card is entered into the drive it takes a second for the sound to load in, which is probably normal. Certain cards give access to the full keyboard, whereas others may only allow half, we don't know if this is by design or a result of a faulty card.

The tremolo section is working nicely, however, the detune and vibrato sections don't appear to function properly. The knob on the far left next to the keyboard doesn't properly work either. This synth has been in storage for ages and has not been used or serviced in years. Some TLC and attention would be advised before counting on it for another Joni Mitchell tour! Otherwise, this synth still sounds great and is currently listed in fair working condition. 

 Fair - There are some notable scuffs and minor chips in the wooden chassis. Mostly notably the back and sides of the synth have a tacky-like texture from sitting in a road case for years where the deteriorating foam melded with the finish. We cleaned the entire unit extensively but the finish will need to be refurbished in order to get rid of that tacky texture. 

However, the top surface, keyboard, and control section are all clean with no sticky feeling. This is good. The pedals are slightly loose from the frame as well. In all, each key, button, and knob is intact and ready for action. Overall, the physical condition is fair.
