“Sequential Circuits Prophet 600.
One owner (me!). Includes power cable, original manual, original sound tape + 2 backup tapes. I have replaced the battery within the last 5 years but I couldn’t for the life of me tell you exactly when. Keypad works, knobs work, Pitch wheel & modulation wheel work….everything on this keyboard still works. Despite the scuffs on the wooden end pieces, the machine is in great shape. I tested it in May before I relocated to another state and it worked as it should. Unpacked in June and couldn’t locate the manual. I didn’t want to sell it without that and it has taken me this long to locate it. Lucky storage box search yesterday! So I’ve not tested it since May, but it has been sitting safely on a bed awaiting the manual. ” Click here to visit listing on eBay
