Performance Music Systems SWAN via VEMIA

"[VEMIA note: If you thought the Syntar was rare, how about this unique instrument?] S.W.A.N Vintage One-of-a-kind very rare monosynth with flight case. The S.W.A.N. is a vintage monosynth built by Syntar inventor George Mattson [of the Mattson Mini Modular]. The S.W.A.N. is literally a Syntar-Without-A-Neck or, a desktop version of the Syntar without the left-hand controller system. This system is owned by George Mattson and it is labeled 'Prototype 1' even though the electronics are stock Syntar circuits. George built it because dealers were inquiring if they made a 'desktop' version. So, he made one. This is the only S.W.A.N. in existence and is a fully functioning system. George has recently replaced all of the caps and tuned up the system. Information and a better picture can be found at Carbon111 The weight is in its flightcase; outside it is 8.2kg. NB Like all of the lots so far in this particular auction, it is being sold as a non-VAT registered item. But if you import anything from outside the EC into the EC, you may be liable to VAT as a form of import tax." You can find it listed on VEMIA - click on Auctions, Search, and then search for 5881.

Update via Stephen Jones in the comments:
"I've played this very synth about a year ago. It has features unlike any mono synth ever made. I really hope this goes to a good home. I'd estimate that its auction value will be about $7400 and even that would be a steal.

It has a Pratt-Reed gold double buss bar keyboard with a good solid feel. (not J-Wire or membrane carbon contacts like everyone else was using)

Its got two oscillators, a ring mod second, noise, an LFO that does audio rates and the same SSM filter that makes the Prophet-5 Rev 2 sound so good.

Good luck and I hope it goes to a good home."

I played this one as well. Amazing synth, amazing piece of synth history. This was a hard one to put up.

Update: someone actually had the gall to list this on Ebay. The auction was quickly pulled.
