“This is a Used Vintage 1984 Korg EX-800 Programmable Polyphonic Synthe Module in Excellent Condition. The person who used this was a musical genius. No scratches, dents, or dings. Please see photos. I do not have the box, manual or power supply, but it was well cared for. Please ask any questions. Pl saw note, it lights up. I used a Korg Power Supply, but I am not including because I have several Korg items and I am not certain this power supply is for this module.”

Korg EX-800

“This polyphonic synthesizer is 8-voice (or 4-voice in the “double” mode). It has a very nice warm analogue sound and includes MIDI. If you’re reading this far, you probably already know what you’re purchasing. Cosmetically it could use some touch-up with a magic marker, but I’m leaving that up to you. The missing screws are’t that necessary, as the unit remains quite solid w/o them. Again, I am not including any cables or power supply, which you can get at your local Walmart or Radio Shack. I’m playing it right now as I write this and I may change my mind about selling it! It sounds awesome!!! Buy it now and ENJOY!!!” Click here to visit listing on eBay

Korg EX-800

“I’ve made some modifications.
I modified it to have real-time filter, resonance, and LFO noise depending on the tone, and to use a button battery as a backup battery.
It has been tested.
I felt that the response of the number buttons was sometimes bad.
The item is only the main unit and the AC adapter.
One of the rubber feet on the bottom is missing, and some of the screws on the side are missing.” Click here to visit listing on eBay

“Selling *AS IS* due to the fact that I have no way to fully test it. I am by no means experienced with synths or this module so please take what I right with that in mind.

~The Synth powers on but the program light only flashes for a millisecond than goes out. I believe the light could just be faulty but I am not to sure.

~Some of the buttons are a little faulty as well. Some don’t feel like they are clicking appropriately.

Those are the two things I’ve noticed with the module by simply plugging it in.

The Korg MS2000R was released in 2000, and designed to capture the iconic sounds of the classic Korg MS-10 and MS-20 in the form of a beefed-up, polyphonic, virtual analogue synthesizer.

The 4-voice MS2000R brings the functions of its predecessors into the modern age.

“Korg EX-800 Tabletop synth with rack ears. Fully functional. Most people would probably use this synth with a modern MIDI controller since many for sale no longer have working buttons, BUT NOT THIS BABY! All buttons and knobs are working just fine. Twiddle and punch away my friend. LEDs in some of the photos only look like they are showing bogus characters in some photos from the cameras shutter speed, they all display just fine.”

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
