Oberheim Matrix 6

“Very nice condition. All the keys and buttons work. Please see pictures.This is the USA Model that runs on 120v 60hz. I took a closeup picture of one white key that was cracked but it was repaired professionally by the previous owner. The patches sound amazing! This has beautiful upgraded ends crafted from exotic wood from Chile. One corner has a small ding but that is the way the ends came to me from the guy in Chile. I still have the original ends if you are interested.” Click here to visit listing on eBay

“This 1986 Matrix 6 is in superb condition! Purchased from Switched On in Austin, TX over the summer. Techs there replaced the LCD, internal battery and updated the IOS & reinitialized the presets 🙂 all keys and membranes work great. selling because i recently moved and no longer have the space.

It does have a minor issue… the right output is VERY quiet. Most likely a 50$ fix.. teks at switched on explained it most likely got jostled loose during shipping.

– 100% positive feedback buy with confidence! 🙂

” Classic Oberheim Matrix 6 in full working condition. No issues on this one.. its ready for your studio or any stage.

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. ” Click here to visit listing on eBay

“OBERHEIM MATRIX 6 Keyboard Synthesizer. Good Condition. Works well! Signs of wear from old age, please see detailed pictures. This synth has been in my smoke free studio since the early nineties. I’m not a keyboardist but I ran a good check-up everything seem to be working fine. The volume knob makes a bit of noise only when adjusting (probably needs cleaning).” Click here to visit listing on eBay

“Oberheim Matrix 6 Vintage Synthesizer in Very Good Condition. Condition is Used. Shipped with UPS Ground.

Synth is in really good condition. I recently took it to one of Chicago’s best synth repairmen to clean pots and fix any inconsistencies in its performance. It’s in better shape now than it was 20 years ago when I bought it. I have the receipt for the work that was done.” Click here to search for synths on eBay

“For sale is my Oberheim Matrix-6. This synth is in great condition. All keys play as they should, velocity and release velocity, (you can modulate parameters by how quickly you release keys), function properly. The membrane keys all work as well as all sliders. It does have some minor wear and tear, but nothing beyond what you’d expect from an almost 40 year old synth. It also has tauntek’s eprom upgrade from version 2.13 to version 2.14 for faster MIDI parameter changes. Version 2.13 is included in a static free bag taped inside the synth. I really really like this synth a lot, but I just don’t play it as much as I used to, and I’m downsizing my studio.

This is a great way to get that famous Oberheim sound without dishing out 5k on an Xpander or OB-8. I’ve owned it for the past several years in my studio (smoke free) and never gigged with it. If you’re not familiar with this synth you can read about it on vintagesynth.com. There are also some great editors for the Matrix-6 online for loading a large assortment of banks and editing parameters.”

“Everything works great on this classic synth! One of the white keys broke and it was professionally repaired with plastic adhesive. I can hardly tell unless I look closely. Please see pictures. Fully operational. Classic Van Halen “Jump” setting sounds awesome! Has custom hardwood ends from Chile! I feel fortunate to have owned this incredible keyboard.” Click here to search for synths on eBay

“Oberheim MATRIX-6 Analog Synthesizer. Classic analog synth from the 1980s.

Never left my home studio. Been in a Calzone case in a corner all this time and recently took it back out, plugged it in and still sounds great. Ran through all the keys and programs, worked perfectly. Excellent keyboard with aftertouch, great as master controller. Hate to part with it and all its fond memories but I don’t have the time anymore.” Click here to search for synths on eBay

“Oberheim Matrix-6 Synthesizer

Original owner, purchased new in 1986 and maintained by owner. Good condition, but hasn’t been played regularly in recent years. Replaced backup memory battery, put new caps in power supply. Checked basic functions, MIDI in/out, external program load, keyboard, front panel settings – all appear to be operational. Passes calibration routine with no errors. Checked DAC and HFO calibration with meter and scope. This synthesizer does have some wear and tear. In the mid 90’s the main board was damaged by an electrical surge which required repairing a trace and replacing the EPROM, micro, and memory. The low C key cracked during a move and was repaired with lexan bracing under the key. The repair is visible but the key is solid. There is a custom port (plugged) next the headphone jack that was used for a custom breath controller board add-on. This board has been removed from the synth. See photos. The synthesizer has not had any problems since. Selling as-is. Keep it going for another 30 years. This package includes:
