Korg RK-100 Keytar

“This Korg MIDI keytar from the 80’s is in museum quality condition! Comes with the custom Hybrid hard case, too.

Everything was tested and seemed to be working as it should. All of the keys, buttons, knobs, sliders are working as they should. Sold As-Is because I have had people switch out components on other items and return them as not working… No power adapter is included; runs on three AA batteries.

The foam inside the case is now is malformed in one spot where the weight of the keyboard pressed on it. It is not returning to shape there. Otherwise the foam should all be ok. The exterior of the case is very good with very few light scratches.” Click here to visit listing on eBay

Korg Poly-61M

“Korg Poly-61M completely refurbished, new oak chassis, new switches, Beautiful ! This synth was in very good condition, even before I refurbed it. I just wanted to create the best possible P-61M I could. It has never had a battery leakage, although I have updated the battery to a modern 3.6V cell battery. I refurbished the keyboard, cleaning it thoroughly piece by piece, and after polishing all the contacts, I applied the little carbon discs to each contact, as seen at sounddoctorin.com. It’s a brilliant fix, so now the keys play like new. Then I replaced all the program buttons’ switches with brand new ones, which fixes the annoying problem of not getting the buttons to work properly. Now, they are perfect. See the photo of the switch board with new switches. Then I built a brand new solid oak chassis for the synth, so as you can see, it is gorgeous, and more solid than new. All pots lubricated, new knobs, all bolts and inserts for the chassis are new, and new feet. Nothing is missing.” Click here to visit listing on eBay

Korg 707

“Ah, the Korg 707. This is an expandable FM synthesizer first produced in 1987. It has 49 pressure- and velocity-sensitive keys and 100 user-editable presets. It even comes with strap buttons so you can wear it around like a guitar. There are quite a few scratches on the bottom, so maybe the original owner wore it and a big belt buckle on stage. Who knows? It also features a slot for a memory card, though I’m not sure which type of card it takes, and no such cards are included.

Please note that there is a chip on the underside of one of the keys; please see photos. There also seems to be a short in the AC adaptor, which may need replaced. This will also run on six C batteries. There isn’t any corrosion in the battery compartment that I could see. ” Click here to visit listing on eBay

Korg MS-20

“I’ll start by saying, the new versions are def cool, but not even close in raw tone. The original is still the real deal. These are quirky, cool synths… the best of Japanese Filters for sure. Gritty, gnarly and more. Two OSCs of sweet tone. Notice there is no screw on the VCA section panel.. this is an original 35 filter version.. known to be much more aggressive in tone and much rarer than the latter filters : )

Ive had this for years, used it for years on albums and soundtrack work. It always sounded killer, always stable too. Had a tech go over it last year, he calibrated it, cleaned all the pots.. its all in great workable condition… but one thing to note.. there is some pitting / rust spots on the metal chassis as shown in pics. Only cosmetic, nothing more than that.. Its been like that for years. Just stating for full disclosure.” Click here to visit listing on eBay

Korg 770

“Here is a 1970’s Korg 770 monophonic synthesizer -beautiful piece of synth history! This thing makes some super weird sounds and is great for creating lo-fi soundscapes, mood pads, and other sound fx. Apparently you can also run external sounds through it though I have never experimented with this. It is fully functional despite some cosmetic wear and tear (see pics) and one missing 3 way Sustain switch. The switch can still be toggled using your fingernail or carefully with a flathead screwdriver. Switch part# is CST023NK if you wish to track down a replacement. The right side panel is missing one placement screw as shown in the fourth picture slide.” Click here to visit listing on eBay

“I’ve owned this item for about 15 years. Purchased from a local music store that had gone over the whole unit prior to purchase. Been sitting in my home studio and has gotten little to no use since purchase. Sounds awesome and has that cool vintage korg tone, but my project never materialized. Tested all keys, tones, knobs, and ins/outs. Everything seemed to work as expected – connected to amp for testing. Some wear on the corners of wood, but everything else is in great shape. ” Click here to visit listing on eBay

Korg Mono/Poly

“For sale is a fine example of the classic and rare Korg Mono/Poly Vintage Analogue Synthesizer. If you’re reading this then you probably already know about the mythical powers of the Mono/Poly. Exceptionally powerful 80s analogue synth, capable of very beautiful traditional sounds or completely wild, devastating patches. This thing sounds absolutely dangerous. The warmth, fatness, depth, modulation capabilities, tightness of envelopes and lush screaming filter resonance are unmatched by anything else. It’s just alive – as soon as you switch it on and hear it you know there are spirits living inside it (these spirits can’t be cloned by Behringer! :).Machines like this just have an unpredictability that doesn’t exist in modern gear. That’s what makes them so interesting to our brains/ears. I’ve used 4 different Mono/Poly’s over the years and although all retaining the same voices and capabilities, they have all been slightly different in their character – which is the beauty of them. Composing with this synth is simply joyous – it leads you down a patch of exploration and creativity, particularly because you can’t save or recall patches. It makes you think and learn. It is a very special instrument and is likely to become the centre of your universe if you become its new owner!

This machine was professionally serviced not too long ago – I still have the service notes and invoice, I’ll dig them out and provide them to the buyer. The original flimsy chipboard end cheeks have been replaced with high quality walnut end cheeks and cosmetically the synth is in pristine shape.Working perfectly and sounding incredible. In excellent cosmetic condition for its age. There will be a void in my life once this thing is gone but all good things must come to an end, and I’ll be happy in the knowledge that it will be twisting somebody else’s mind for many years to come.Collection in person is ideal or I can ship with tracking and insurance for the instruments full value for £40.” Click here to visit listing on eBay

Korg Poly 800

“You are bidding on a Korg Poly-800. This is a classic analog synth from the 80’s. I am the original owner. I bought it brand new back in 1985, and it has always been kept in a dry, smoke-free environment. All the keys still have their original spring action and work perfectly. The joystick and all the buttons work perfectly as well, and the display is nice and bright with no faulty segments.

Cosmetically, the synth is in great shape for its age. There are some minor scuffs and scrapes, the worst of them being along the rear of the unit. The only other cosmetic blemish of note would be the bezel surrounding the joystick. At one point, the adhesive lifted and the bezel got snagged causing it to crack (see photos). I have taped it back down with some double sided tape, but it is starting to lift back up. It should probably be glued down, but I’ll leave that to the new owner.

I am including the original Korg power adapter, the original cassette tape with all the default sound files, and the original instruction manual.” Click here to visit listing on eBay

Korg Mono/Poly

“For sale is my KORG MonoPoly serial number 378518.

Operationally everything works as expected. One or two pots in the filter section (EG and track in particular) had become glitchy and showing symptoms of requiring a good clean. The unit has therefore been recently stripped and rotary controls and key contacts have been cleaned. At the same time tuning has been re-calibrated. This work was undertaken by Electrofix (Bristol).

Cosmetically the keybed and top surface of the synth are in good condition for the synth’s age. The side cheeks have at some time sustained damage on the corners and might benefit from repair or replacement.

At some stage there has been a modification in the form of an additional switch (visible to the left of the Korg logo on the top panel and above the main output volume knob). This purpose of this switch is unclear, the wiring links to the CV in jack – when not engaged the MonoPoly operates perfectly normally.” Click here to visit listing on eBay
