"A very much underestimated 61 note powerhouse capable of some very nice sounds. Very much aimed at the DJ market, with hands on realtime controls. Control filter resonance and cutoff in realtime + envelope. Map your own control to two assignable knobs. This synth is capable of some massive expansive pad sounds using yamaha's AWM2 synth engine. Capable of producing some killer bass sounds. This synth has been repaired and serviced and is in 100% working condition. All original knobs and controls are intact. As can be seen from the pictures, this one has had some extensive repairs to the case using aluminium checker plate..."

"Very interesting synth this one, no way of naming it for you but based entirely on the build quality this feels extremely high end, a really nice home build project. All the rotary dials and switches have a lovely resistence to them and I've been told uses CEM chips. No MIDI only the CV gate - would recommend that it is collected to avoid obvious issues in shipping."
Update via elgauchoandres in the comments: "It looks like the E&MM Spectrum w/o logo and some mods"

"For sale is a rare Sequential Circuits Instruments Prophet VS vintage analog/digital synthesizer. This is one of my favorite synths of all time, the first synth that had Vector Synthesis. Every aspect is amazing, the arp/sequencer, filters, waveforms and especially the joystick. Perfect for ambient pads, effects, soundtrack composition, but also with analog acid basslines, leads and more. This synth is in excellent shape and fully functional. Never had to do any repairs. I did upgrade the unit's CEM5530 chips (part of the audio output section...these chips are typically first to die in the VS) so it will be very reliable for years. SCI WinteCountry tech David looked at these chips and said they were great drop-in replacements and provide an slightly cleaner sound over the originals (included is a pic below showing the board). It also comes with lots of bonuses worth over $800:
- 3 Cartridges, including two RAM carts and one ROM cart. These are quite rare. One of these ROM carts is loaded with great Fairlight sounds. RAM carts are more valuable because you can also save data (patches and waveforms) to them. These cards typically sell around $200+ each.
- Original Manual
- Lots of spare parts including spare battery, capacitors
- Custom made LE dust cover
- Power Cable
- Additionally I have lots of saved file patches I can email that you can then load over sysex, along with a couple other email bonuses."
