Oberheim Matrix 1000

“This Matrix 1000 has been fully pro-serviced unlike most and working great. We paid our tech to perform a necessary power supply modification that most other sellers don’t do, cleaned the potentiometer, and replaced the internal battery, which most sellers also don’t do. This item is being sold by professional perfectionists and will be packed to withstand rough handling. You get what you pay for.” Click here to visit listing on eBay

Oberheim Matrix 1000 Project Machine

“Please read for complete description of the synthesizer.For sale is an Oberheim Matrix 1000 analog synthesizer. I purchased this unit about 5 years ago from a college music professor. It was fully working when purchased and has sat unused for years. I recently powered it on to test it before listing it for sale and it displayed the “1.1.1/6.1.1” error message on the screen. I powered it off and on, and it then worked perfectly fine. All of the buttons work perfectly, all of the inputs and outputs work, the volume knob works perfectly, and it sounds absolutely AMAZING. I left it powered off for a week and went back to it. I powered it on and got the “1.1.1” message, I powered it off and back on, and once again was able to get everything to work perfectly fine. Looking into this error, it looks like an issue with the back-up battery. I don’t have the time or money to spend repairing it so I’m looking to sell it “as-is”, though I’m sure its an easy fix for someone who is familiar with vintage gear. I meticulously package everything I sell and ship ASAP. Because this is a “For parts or not working” listing, I will not accept returns on this item.” Click here to visit listing on eBay

Oberheim DMX

“Vintage 1980’s DMX oberheim drum machine. It powers on and has been tested by a professional. It makes sound, but has not been hooked up to an amplification system. To our best knowledge it is nice condition. It’s missing one thumb screw for cover.” Click here to visit listing on eBay

Oberheim Matrix 1000

“Oberheim Matrix 1000. Condition is “Used”.

I have owned this unit since it was new, and it has remained in my smoke free, temperature controlled studio ever since.

Everything functions as it should and it is fully operational. I am meticulous with my gear, and this piece is an example of that.

There are a few very small scuffs of the top from rack removal, but otherwise it’s perfect. Cleanest one available. ” Click here to visit listing on eBay

Oberheim OB-Xa

“In good shape visually, several minor scratches and stains on one of the wood sides. Also, one of the wood panels is slightly warped due to aging. Seller has owned this iconic synth since 1984 and used it in studio environment.

Keyboard is in great shape, plays and sounds like new.” Click here to visit listing on eBay

Oberheim OB-Xa

” Electronically restored 2 years ago. Recapped and most pots replaced. Plays Great & Sounds Great. All new foam in the case too.

Knicks are threefold:

#1. If you want it perfect, the case will need to be stripped and repainted and then re-silkscreened. There are companies out there that do this. I just wanted it to play properly, so the fact that the finish on the case isn’t perfect never bothered me.

#2. The Pratt-Reed keyboard plays fine, but the key dampers should be replaced. You get a little mechanical noise when playing. I used it for recording, so it never bothered me.

#3. The unit has a JL Cooper MIDI interface. It worked when I got it, but after I had the service done it stopped working. Again, there are other companies out there offering MIDI kits for this keyboard.” Click here to visit listing on eBay

This is a unit I’m not terribly familiar with, I received it with some other musical equipment. Unit powers on and buttons and knobs all seem responsive.

Oberheim OB-8

“I bought this synth to use in my band and studio in 1983. I haven’t played it in about 20 years but the repair shop (Spectrum Sound – Indpls) inspected everything this year. I’ve included a receipt showing the condition. “Voice 3 fails autotune (bad CEM3340), voice 4 sounds bad filter circuit issue. Many keys don’t play (bad rubber key contact strips).” The outside appearance is nearly perfect except for a single scratch visible in one of the pictures which was actually caused by the leather case with zipper I had custom made for the synth. With a little TLC and a few minor parts, it should be fully functional.” Click here to visit listing on eBay

“Oberheim Xpander XP-1 6 voice desktop version of the Matrix 12 US version. Condition is “Used”.

Studio use only, non-smoking. Always covered. All functions work, programs easily. Every button functions normally, yet occasionally may require pressing again.

Does not have any outstanding physical flaws all leds perfect.” Click here to visit listing on eBay

Oberheim Matrix 1000

Has the classic Matrix 100” transformer poser hum, but they all do that. Good shape, minimal rack rash. Classic ballsy 80s synth with tons of possibility! Oberheim Matrix 1000. Condition is “Used”.” Click here to visit listing on eBay

Oberheim Matrix 1000

“Oberheim Matrix 1000 6 voice polyphonic analog synthesiser.

Visually a bit tatty, the faceplate is slightly misshapen and has some rack rash and a few other small marks. The volume pot is also a little bit loose but functional.

1 of the voice chips has failed and needs replacing. I have been using the synthesiser without much problems without it as not many of the 800 presets use all the voices, but you do notice it occasionally. I purchased a new CEM 3396 narrowbody to do this but never got around to it, same story with the firmware update. Both of these are very easy pull out/push in jobs, but while it’s opened up probably worth switching out the battery for a battery holder/button battery (requires some basic soldering), although seems to be fine.

Once you get the new firmware in you have a couple of options for ‘real-time’ control. One of them is an £800-ish controller from Steroping, Another is patchbase which is around 30 quid and works on your computer or iPad.

Comes with the original instruction manual which I have forgotten to photograph but will add tomorrow.”

Oberheim Xpander

“You know what this is… This is the most advanced, most elegant sounding Oberheim of them all.. besides the Matrix 12. She purrs… she growls and so much more. Once you play it, you’ll instantly recognize all those instant classic 80s sounds. Not many synth freaks have one.. most have never played one. This synth is not for the faint of heart. It delivers in every way.” Click here to visit listing on eBay
