Matrix 6R

” One of my favorite “toys” of all time! The sounds from this unit have a spacey, glassy quality that are hard to find anywhere else. Lightly used in a home studio and stored in a cool, dry environment. Comes with power cable and original manual.”

“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.”

“This unit went has been sitting in my studio rack, used very little since 2003. After recently taking it out for testing, here is what I found. The unit powers up just fine. Midi signals are received just fine. Sounds are great. Audio output at the rear 1/4 inch output jacks is only present at the LEFT/MONO jack. Headphone out jack works normally both left and right. No issues with switches. The front panel is in very nice cosmetic condition, but the sides have some surface stratches from being pulled in and out of racks(all pictures are of the actual unit). Made in Japan. USA Only shipping. Unit and power cable only. No manual included.” Click here to visit listing on eBay

“Undeniable, unbeatable, classic Oberheim sounds! The real-deal analog sound powered by a digital architecture and membrane buttons for programming.

CONDITION: Very, very clean condition for its age (1986) and fully functional with zero issues. Regarding cosmetics of the unit, there is a slight divot on the “4” button along with the typical, slight rack rash along the top rim of the unit that is to be expected from being mounted and unmounted within racks over the years.

NOTE: A custom-machined pair of 3U rack ears WILL BE INCLUDED as part of the sale.” Click here to visit listing on eBay

“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
