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

Classic 80s grooves, on many early Madonna records, this one has MIDI which makes it easy to connect with modern gear. Drums are tunable by turning the jog wheel on the boards inside, each sound has its own board(a few are combined)!!! Talk about hands on!” Click here to visit listing on eBay

Ok ..here we go…Here’s our Ob DMX that’s been in our studio “forever” lol!. Recently inspected…battery has been swapped. Led’s work perfectly. Has the midi kit where the I/O was put into the side panel. The fun thing was I had a box made in which the tunings were able to be changed via using the CV port in the back. You just need a 9 volt power supply. There’s roughly 90 or so eproms that im including. You only see 53 on one side…but if you flip that foam over there’s more! SURPRISE!! lol….that’s around $800 usd in chips alone…so go ahead…” Click here to visit listing on eBay

Oberheim Matrix 6R

“This is a 120v unit which has been professionally converted to 240v, but can easily be converted to suit most regions. Will not be supplied with a power lead as it is just a standard kettle cord readily available in every country. Will require a step transformer if using outside a 220-240v region.” Click here to visit listing on eBay

Oberheim Matrix 6

” Classic Oberheim Matrix 6 in full working condition. New battery installed last month as well!

This synth has that unmistakable OB sound at a price that is way more affordable than an OB8, OBXA!

Although you can fully edit any sound and create some wicked lush sounds.. I used a software editor to speed up that process. There are many great editors for Mac, PC and IOS.

This Matrix is in great condition in and out. No issues.” Click here to visit listing on eBay

It delivers in every way.

This is the Made in USA version not the inferior made overseas version. It was fully overhauled by a veteran analog synth tech. The main encoders were replaced with new stock certified pots purchased by Syntaur Synth Parts. It was also calibrated and tested over and over again to ensure years of usage to come. It sounds amazing, and it works as it should.. NO operational errors here. Plus as you can see from the pics.. it looks fantastic as well.” Click here to visit listing on eBay

Oberheim OB-Xa

” Sadly, the time has come where I need to sell my beautiful Oberheim OB-Xa synthesizer. This is an early 8-voice 32-program version of the instrument (serial number 813313) with the wonderful Pratt-Read J-wire keyboard, but two of the voice cards were removed before I bought it so it’s currently a 6-voice.

The synth is in very good condition on the outside and exceptionally clean on the inside. See the pictures taken in broad daylight.

I began the process of repairing the instrument, but further work is needed. The unit powers up fine, all buttons light up as normal, and the autotune runs to success. But for some reason all 6 voices are making a warbled, static-y type of sound. I don’t know why.

When I bought the instrument, the voices tuned and played perfectly, so I think the voice cards are fine. The left hand controller is need of repair. The levers are not functioning correctly and the plastic rate and depth knobs are missing.

This is what’s been done:

Replaced most of the 4000-series logic chips on the upper and lower control boards
Replaced all keyboard bushings, fixed any broken J-wires, cleaned the bus bar and all and leveled the keys
Replaced the battery
Cleaned all pots

I am not a certified technician and it became clear to me the extent of the repairs are beyond my capabilities. This is a great synth with the rare P&R keyboard. Sadly, the time has come for me to pass the baton to someone who can complete the work.” Click here to visit listing on eBay

Oberheim Matrix 6R

“I’m the original owner of this Oberheim Matrix 6R analog synthesizer module. Originally released and built in 1986, these rack mounted synths were emblematic of that Oberheim sound – thick, synthesized waveforms. I’ve had this rack mounted in my personal smoke free studio since I purchased it in the late 80s. It’s in excellent condition, with only a few rack rash marks. I recently tested it out, all seems to work well. Software version 2.13.

Although it doesn’t currently need one, I recently bought a back up battery, which I’ll send along for those who know how to change it. I also have the original manual and a cassette that came with it, containing 1000 sounds. There are many other ways to upload sounds via MIDI which can be found online.” Click here to visit listing on eBay

The V2.14 Firmware provides much better midi response and allows use of the Beautiful and Free CTRLR Matrix 6 editor.
