“This is the one! All original knobs, buttons, switches, ends, etc. are present. In overall good condition- see pictures. Has some blemishes and scratches, but nothing obscene. Wood ends are dinged in places.
This unit is in excellent working condition. All notes and functions work as they should. It was serviced about two or three years ago by a famous Boston tech who used to maintain synths for the band the Cars, and who used to work for ARP.

I paid significantly more for this two years ago than is the average going price due to the amazing condition (see pix). The only marks it has are due to age but I’ve never seen one with all original parts in such great condition. It has never been toured and only kept in studio.

Just a note that the Gator case itself is well used (see pix) but is perfect for housing and looking after this synth.”

Please note that one of the keys is noticeably broken (shown in pic) Beyond that no further testing has been performed. ”

“I do not want to sell this.
