“It is KORG’s six polyphonic synthesizer “PolysIx”.
It is a perfect analog synth, six sound polyphonics with timbre memory.
Before exhibition, we replaced the sound protection battery with a new one, and it has returned to the factory preset tone of KORG.
In addition, 2 chips of VCF [SSM 2044], ordered genuine from overseas and replaced it for a new one.
It also has an arpeggiator and plays a very wonderful sequence.
Although there are small scratches and rubbing with use, I think that the state is a good one considering the times.
Functional:
perfect working.
It has been tested by musical instrumental shop in Japan.” Click here to search for synths on eBay
“Up for bid is my 1986 Korg Poly 800 II. I acquired this Synthesizer back in August, and after some use in my collection, I’ve decided to let it go. The keyboard itself is in good condition, but you can certainly tell it was a well loved synth. There is wear on the finish of the plastic, which reveals a shiny undercoating, however this does not affect the playing quality at all (see pictures for more details). It has a set of custom patches pre programmed through midi, so if you want the stock factory patches, I can certainly do that for you if you send me a message. It does come with a custom fitted gig case, but if you don’t need/want it just let me know! All of the keys are in perfect working order, and there are no mechanical flaws whatsoever. It also comes with the original power adapter. Thanks for looking, and happy bidding!” 
“Hi,
“Olivia’s Vintage would like to present this RARE 1980’s Korg MS-04 Modulation VCF pedal that is made to work with vintage Korg analog MS synthesizers and will work with the Korg X-911 guitar synthezier. It has been tested with an X-911 unit and everything works great. This pedal really opens up options for manual foot control of modulation features. It’s in great condition with only minor cosmetic wear.” 
“Korg Polly mk2 with Moog slayer mod. Comes fully working. Generally the condition is good but, it is old and does have signs of use. There is also a faint postcode that has been written with what looks like a security marker pen, but is hardly noticeable.

Keybed is in good shape but has one squeaky key. All sounds and keys work, some of the presets have defaulted to INIT. the board will probably need to have the original sounds reinstalled. Overall in decent condition that needs a little TLC. Will Pack Securely in foam and doublewall Cardboard. Priced Accordingly”

“Selling my Yamaha DX7, I got this keyboard in 1985, it’s held up great and still works excellent. The sounds and capabilities of this synth are so iconic and smooth. A grail.
“Tested – Fully functioning – Some scuffs and wear from being rack mounted. Works just like it was 1987.”
“This keyboard has the original, more desirable metal casing. Recently serviced. It works well and is in good condition. There is a dent on the left side (as shown in picture #4). There are currently no patches stored in the memory. Like most people (except Brian Eno) I don’t know how to program the DX7 and can’t test the memory; however, the battery was replaced a few years ago. Included are a cartridge containing the original presets, a sustain pedal, a volume pedal and a breath controller. Sold as is, no returns.” 
” 1984 Sequential Circuits Six-Trak in great condition, serial #245. I bought it from a sixth form college last year as the department that owned it was shutting down. I’ve since replaced the memory battery and reloaded the factory presets. The synth is now fully functional with all 6 voices, filter, LFO, amp, sequencer, stack, arpeggiator, wheels* etc working perfectly, and makes some really great sounds in poly, unison and stack modes. It works with a foot controller though I’m not including one.
“SEQUENTIAL CIRCUITS PRO ONE SYNTHESIZER
“Classic analog synth with amazing fat leads, lush brass, atmospheric pads and filter sweeps from early-mid 1980s, with MIDI, comes with hard case.
“I recently acquired this from the original owner. I was able to load disks and the samples seem to work fine. All keys seem to be working as well. I was able to use the Arpegiator and Filters. Since I’m not an expert in the keyboard I’m not sure if it’s exactly 100% functional. Sold As-Is. Some of the included disks didn’t load but a lot of them did.”

“* Superb shape; low hours, no issues with keyboard, knobs, buttons or controls, displays or audio outputs. Fully rebuilt from ground up. Original owner. Home use only. Never gigged, leased, rented, used in studio, or abused in any way.
“Does not have powercord for testing. Two keys seem to have missing spring inside and one is cracked underneath. Overall, the surface of synth is in excellent shape, and the inside circuit board free from deterioration.” 
“This incredible keyboard has unique rich warm sounds I have not been able to create with any of my other synths. It has been gently used in a climate-controlled smoke free home studio and has always been covered when not in use. It is in excellent condition, all features function well, and I have had no problems or issues with it. There are many rack mount Q’s out there on eBay, Reverb, and other sites, but the Waldorf Q 61 key keyboard synth is hard to find, especially in this superb condition. ” 
“Casio CZ 1000 Synthesizer in primo condition. Includes instructions, Sound Data Book, 3 ram cartridges, electrical power supply, assorted midi cables and dust cover. A relative of mine bought this brand new years ago and it ended up stored in a forgotten closet. It surfaced last year when the house was being cleaned out to be sold. I already have too many musical toys for it to land in my house. But anyone who likes to make music would really appreciate this instrument. By the way the ram cartridges all have been fitted with new batteries. Happy bidding.”

“For sale is an Oberheim Matrix 6R from my personal collection, owned for many years. Hardly used and kept in smoke free home studio. Fully functional. It’s in good shape, it does show some signs of wear as expected for its age. The only issue worth mentioning is its missing the cap for the slider shaft, but the slider is still there in tact and working as it should. Check out the pictures to make sure you like it.”
