WORKING CONDITION: Excellent. The key action is great, and both pitch and mod wheels function smoothly. All presets, sequencer modes, knobs, and buttons function properly. The display is sharp, and all parameters/values are accessible without issue. Tuning is stable, and the unison mode sounds massive. 

PHYSICAL CONDITION: Very good. There are a few knicks in the wooden end cheeks and the metal work, but in all, this vintage synth is beautiful, and all of the iO jacks are straight. A newer 3-prong grounded power plug was added at some point for safety.
