Korg PS-3200

” For sale is my Korg PS-3200. This is an amazing analog beast, fully polyphonic & sounds gorgeous. Easily my favorite polyphonic synth. Anytime I power it up, it just puts forth inspiring sounds…warm, full analog tones. Super rare, these don’t show up for sale too often. This is a once in a lifetime chance to own one of the greatest synths ever made. I recently took this to my professional tech for a full restoration, including a full recap of all 18 cards & power supply, new batteries, cleaning up pots & keyboard keys, tuning & calibrating, etc. It’s plays beautifully & is 100% fully functional. Cosmetically it’s in excellent shape, a few scratches on the wood but the front is very clean. Includes the main unit, keyboard & remote along with two connector cables.” Click here to search for synths on eBay

I don’t have the time or the money to troubleshoot it. This is an excellent opportunity for someone who knows how to fix keyboards. This is a keyboard that used to be used by Tony Banks from Genesis.

Korg EX-800 Project Machine

“This Korg EX-800 Synth Module is in VERY USED condition with dents and scratches all over. It had some hard use back in the 80s – I know because I used the heck out of it! The internal battery is good and the patches are all there – some may be custom/altered from the original factory patches but I think what is in there is better anyway. I have fully tested the unit and it works fine – sounds just like it should – I forgot how awesome these old modules sound! Anyway, here it is – A Generic Power Adapter is included!

The unit needs button repairs and is missing the “BANK HOLD” button cap – some of the buttons are intermittent but the rest of them are still functional. See pics!” Click here to search for synths on eBay

Korg SR-55

“Every knob and combination of buttons has been fully tested and works fully. Both outputs on the back also work great, the pedal output was static filled so it may just be that i wasn’t using it correctly as I have never used that output in the past. It is overall in very good physical condition for its age. The rubber mounts on the bottom are all there, some do have cracking. One of the back rubber mounts is missing (see pictures). The power cord is a little stiff but works great. Overall a great playable drum machine for any musicians collection.” Click here to search for synths on eBay

Korg SR-120 Project Machine

“This plays its sounds. All the buttons and patterns work.

There’s static noise that also plays. It didn’t do this a few years ago when it was in perfect health.

My guess is that one or more of the capacitors is dying or is dead. If you don’t have the skills to know how to fix this, you’ll have to take it to a shop.

There seems to be a lot of broken SR-120’s showing up for sale and I think this is a standard issue. Capacitors tend to go after a few decades. You probably don’t want pay a lot of money for one that is working correctly and hasn’t been serviced because it will likely go wrong on you. If you’re going to buy one, ask about when/how it’s been serviced.” Click here to search for synths on eBay

Korg Mono/Poly

“This auction is for a used working Korg Mono/Poly analog keyboard synthesizer. This synth has been stored for about a decade, kept clean and dry in a hard case. Prior to being stored the synthesizer was used in a smoke free studio for about 15 years. I am the second owner of this Mono/Poly. This synth is US shipped only.

The synth is working, it powers on and produces sound. Going through the synth all knobs and switches are working, all 4 voices, waveforms, noise source and the VCF/EG/VCA signal chain are working, all ins and outs are working. The arpeggiator works, latches and holds, and will cycle through the 4 vcos, warping them in a deliciously twisted manner when using the X-Mod effects in poly mode. All push button switches are working and all leds work. The pitch bend and modulation wheels both work. Both LFOs (MG1/2) are working on all waveforms at all rates.

Cosmetically the synth is in good condition. The metal casework and front panel are clean and legible with no dents and only minor wear. The factory particle board wooden sides suffer from fragility and are worn at the corners, ugly but purely cosmetic. The synth has not been modified in any way.

While the synth powers up and it is working it also exhibits the typical symptoms of a vintage analog synth coming out of long-term storage. The keyboard seems to have suffered the most during storage as there are now many intermittent keys. In addition most pots and switches exhibit audio signal noise when used. The synth will need servicing to be brought back up to spec. I am not a tech and it will be up to the buyer to determine any needs.” Click here to search for synths on eBay

Korg Poly 800 with Moog Slayer Mod


This vintage synth today is highly sought after of, It was Korg’s answer to the Roland Juno Series, but this one here goes a bit further it was properly upgraded and installed with the Moog Slayer Mod: which massively expand the functionality of the analog filter inside the poly 800 synthesizer. The “moog-Slayer” modification involves externally mounting the trim pots for adjusting VCF cutoff and resonance. With this modification the internal VCF CUTOFF (parameter 41 and VCF RESONANCE (parameter 42) acts as a master setting for the particular patch. The added controls can only sweep down from this setting, so be sure to set them high. BE CAREFUL with this modification the filter will oscillate if the resonance is set to 13 or higher.

Also installed is a Filter Input.The Filter input allows you to run any line level audio signal into the poly 800. The audio will be affected by the VCF, VCA, and Chorus and come out the keyboards main output. This filter input has a level control so that you can mix the audio with the keyboards internal voices. If you want to pass just audio, make a patch here just DCO 1 is on. Turn all the individual tones off (4′, 8′. 16′ etc) make sure the level for oscillator 1 is set pretty high.

Upgraded Blue Display

Brand New Internal Battery installed (good for years), also has a Battery Holder, so internal battery is User Installable.

Generic AC Adapter Included with voltage range from 100-240v
