Korg EX-8000

“Unfortunately, this unit is not outputting any sound, so I am selling it “as is, not returnable, for parts or repair.” I don’t know if the issue with no sound is because I have a bad midi cable going into it, if it needs a new battery (which I believe is a common problem in these older synth modules), or if there’s something else that needs to be repaired. In any case, I’ll be offering it for much less than a fully-working unit, so it may be a great value for someone who can troubleshoot and repair it.

It comes with the EX-8000 unit (with attached rack ears) and the power cord. That’s it. Find the manual and other information online. Syntaur.com appears to have many parts available at low prices, including the battery (which must be soldered in) for about ten dollars.” Click here to visit listing on eBay

Korg Poly-800 Project Machine

“You are bidding on a Korg Poly-800 synthesizer for parts/project. This synthesizer was working, but had been partially disassembled to install some modifications (moog slayer,) which were not completed (only knobs/pots installed.) It has sit on a shelf for some years waiting to get the attention it deserved, but unfortunately I have not been able to find the time for it, and I must now regrettably let this awesome synth go. I hope it finds a new owner that can give it the attention it needs.

Please understand that this is a PROJECT synth that will require some work (or to be used for PARTS for another poly800 project.) With this in mind it is being sold as-is, so bid accordingly.” Click here to visit listing on eBay

Korg MS-20

“This vintage Korg MS20 keyboard synthesizer, originally released in 1978, is a classic piece of retro equipment that any musician would love to have in their collection. With its semi-modular design, it offers endless possibilities for creating unique and original sounds. It is an excellent addition to any studio or live performance setup, and is sure to provide countless hours of creative inspiration.

This one comes in excellent condition, believed to be fully operational, but I haven’t tested every single parameter so this is not a guarantee! All keys and knobs are working as expected though and all insert points look clean. Serial number is below 150k which indicates that this is the Mk1 model with the better filter. Sold as is, so strictly no returns!! Buyer welcome to test fully on colection.

It’s fitted with a Japanese power cord requires a step converter to run from UK mains supply (NOT INCLUDED) AirLink trasnformers are recommended by SoundGas and are particularly reliable unlike some of the cheaper Chinese transformers, which I would never trust with one of my vintage synths!!!”

Korg MS2000R

“Originally purchased from RubADub in 2008. It’s been racked since, in a clean, smoke-free studio. There are two cosmetic issues to note, but the unit is fully functional. 1. The upper right corner of the rack ear is bent. It doesn’t prevent mounting, so it’s purely cosmetic. 2. My insurer used to require use of smart ink, which I tried to remove before selling with isopropyl alcohol. It did remove it mostly, but in the right light you can still spot it. Given that the ink was mainly transparent to begin with, this is a really minor thing to note, but I just wanted to fully disclose. I’ve photographed both of these here. Comes with manual and original PSU, but not the original box. Selling a bit cheaper than the average price per the cosmetic issues, but there are no functional problems to note.” Click here to visit listing on eBay

This one is in tiptop condition for its age and has been thoroughly disassembled down to the individual keys, cleaned and reassembled, then tested and adjusted to ensure it is working perfectly. See the video of it in action.

In essence, w.y.s.i.w.y.g. with the EXCEPTION of the patch cables.

An ever increasing asset to the studio, whose price in this condition is only going up.

Included is a print-out of some of the sound variations possible.

Korg Delta

“Here’s an amazing string synth I picked up I think in 2009. It’s an amazing synth, and I’m reluctant to let it go nut I need to clear out a lot of my equipment in preparation for a change of use for my studio.

It could definitely do with a bit thorough service to fix a few minor and a couple of major issues.

Cosmetically it’s surprisingly good, see photos.

Main issues.

Intermittent problem with what seems like the synth section Low Pass Filter. It often seems completely fine, but occaisionally will start to distort and fluctuate in amplitude resulting in a very unpleasant crackle and then starts to lose function, the resonance stops working and only the top range of the filter cutoff seems to work. I think it may be linked to heat as it seems to happen more often when it has been left on for a while.
The synth section works seemingly much better when set to Band pass mode, though which Is how Ive been using it for years without any issue.
The noise generator in the synth section seems completely none functional, both as a tone and modulation source.

There are some issues with some of the faders/pots, as follows. .

The vibrato depth pot is missing its cap but functions fine.
Seems like the sustain parameter on the synth section is locked at maximum, so there’s no way to know if the decay functions correctly, but I’ve always managed to make do with it by using the release to create any pluck sounds I required, though maybe lacking slightly in precision compared to using the decay.
The two pots that control the amount of modulation assigned to the joystick are a bit temperamental and inconsistent while making adjustments but seem fine once in place and the joystick itself works great.
The octave blender in the string section seems very slightly off in the lower ranges when blending towards the lower octave.

The last photo shows the pots that have issues.
Note: The far right pot (Main Volume) is actually fine despite being labeled in the image.” Click here to visit listing on eBay

Korg Poly-61

“**Local pickup only**

Here we have my

Working KORG POLY-61 Vintage 1980’s Synthesizer Keyboard

I have had this a long long time, and over the years it has seen more action than Axel Rose.

Over the years I have had hard Red Oak sides put on, as the chipboard that was originally there was just falling to bits as they all do.

I have not used it for over a year, but it is fully functioning. Just needs some switch cleaner in the volume knob as it is a little scratchy when turned. With time and use this should dissipate.

Also, where the modulation/Pitch bend joystick is, the panel does move a bit. It has done this since the sides were replaced but it does not affect playing or using of the joystick. It could use some shorter screws in it I think. Just never bothered with it as it did not detract from its use. Just thought I would mention it as someone may want to fix that.

Other that what I have mentioned , it is working as it should.” Click here to visit listing on eBay

“We paid our tech for the 15 hours of skilled labor required to meticulously service and upgrade this Polysix the right way, without cutting corners like most other sellers do / making it more valuable than lesser examples you may find. We are professional perfectionists with decades of experience and an exceptional level of customer satisfaction, so you’ll get what you pay for.

In addition to the cost of this item plus its proper restoration, we invested around $500 in 2 important upgrades – 1. a Kiwisix MIDI retrofit (which adds excellent MIDI control other retrofits don’t offer that takes this synth to a whole other level), and 2. a new Kiwi power supply board that’ll hopefully extend this unit’s life way beyond that of others you may find that don’t have this new power supply. ” Click here to visit listing on eBay
