Oberheim Matrix-6R

“Works great and sounds great. These Matrix racks sound a lot better than a lot of modern synthesizers. It comes from a smoke free home. It is being sold as is, it still has the original battery, the next owner should change it. It also still has the original presets. Lots of modulation capabilities. Really easy to edit patches from the front panel. FREE shipping for the USA only. Checkout my other listings ”

Oberheim Matrix 6R

“I have for sale my Oberheim Matrix 6R Rack Mount Polyphonic Synth Serial #KGB4919 from the original owner.
This product was purchased in the US and will ship from our studios in CT.
 
Considering how old these are I would put this in the “excellent” category, however it does have the usual amount of scratches on the top and bottom from other rack gear being installed and removed. There are some minor scuffs and specs on the front but please check the photos to 1) see if you can notice them and 2) make note if they bother you. 
Otherwise, it works perfectly. I recently sold my mint condition OB-XA so I have a good handle on Oberheim products, so feel free to ask any specific questions or you can download the manuals from various sites as well.”

Oberheim Matrix 6R

“I’m the original owner. Bought it some time in the late 80’s or early 90’s. Used it on various commercials and multi-media projects until around 2004, when I left the biz. It’s been sitting in a rack in my smoke-free, personal studio since then. It hasn’t even been powered up much in the last 17 years. It was in very good cosmetic condition, until I tried to clean the sticky residue from a label off the top left front the other day. That cleaning solution caused the finish to smear and look ugly. I’ve tried to provide several pictures and angles of that discoloration so that you can see it clearly. There’s also a light scratch in the upper right part of the display.
I’ve tested its operations, and it’s working great, midi connections and response are good, and it’s still got that fantastic Oberheim analog synth sound. I reset it to all the factory original presets. I even still have the manual.” 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 search for synths on eBay
