I can't tell if the SN is P55010, P55020, or other.

"As rare as these are, it is far rarer to find one in absolute mint condition, fully restored, modified with an internal fan (to mitigate the notorious overheating issue with these), extra CEM chips, original 194 page owners manual in great condition AND the original and rare 12 page GBC bound quick start guide! I'm in absolutley no hurry to sell this one. It's just a window display for the shop really, unless someone wants the cleanest, best one money can buy. When I say the wooden sides look brand new and don’t have a single scratch, I mean this one belongs in a museum. All the buttons were cleaned and serviced by a professional, some minor components like aged capacitors have been upgraded to highest quality versions and the unit has always been stored in a climate controlled, smoke free home studio by all three owners.

When it was released, retail price was equivalent to today’s retail value of over $18,000. Can you imagine buying it new for that in the 80’s? No wonder so few were made (from 1985-1991 only 1,000 were produced).

I am the third owner. I don’t need to tell you that this is quite possibly the greatest synthesizer ever made. It is arguably the greatest Oberheim ever made as well. With 15 LFO’s and VCA’s per voice, this thing is an absolute beast. It even has a self tuning feature that recalibrates itself."

"It is known for it's unique sonic character, can basically do anything, drums, pads, stabs, noises, glitches. Has been used with a lot of care and only in a professional recording studio setting. I just don't have the use for it anymore unfortunately. Next to it's unique character in sculpting various sounds and bleeps and noises and it's very own sonic aesthetic (used by artists like Actress, Tom Yorke, Autechre, Sophie, Chemical Brothers to name a few), it's programming possibilities, usability in digital and analogue setups are endless."

I thought the price was a bit too good at only $689.00 for this one, but it's disfunctional. This one is for the techs/DIYers out there.

"FUNCTIONING WITH DEFECTS

This is a very rare example of the Vermona MARS synthesizer and Control unit.

The Control unit is responding as it should with the head unit, and all menus and buttons seem to also be working on the head unit.

Known issues:

Head unit produces sound and is affected by keyboard presses, but for some reason the LFO keeps running and cannot be turned off, also the Filter and Envelope Generator are not responding (even though the Control unit changes their parameters)

This could be a great project for someone looking to repair and get a great deal on this very rare synth, or get the head unit for parts and a fully functioning Control Unit."
