“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 6

by

“Oberheim Matrix 6 Vintage Synthesizer Excellent Condition with Manual.

The Matrix 6 is an analog polyphonic synthesizer with six voicesof analog goodness and a deep modulation matrix, including key pressure andvelocity as modulation sources. It’s a great way to get those classic Oberheimtones, from silky smooth brass and strings to cutting bass and leads.

Note that the Matrix 6 does not have a stereo output, despitethe fact that there are two output jacks labeled Left and Right. These are NOTstereo outputs – they are for setting up keyboard splits with separate outputs,as described in the owner’s manual. Unless you specifically have a split patchset up to feed the Right output, you will get no audio there.” Click here to visit listing on eBay

Oberheim OB-8

by

” Vintage Oberheim OB-8 Owned By Legendary Bob Siebert w/ Hard Case + Extras! Synthesizer itself is in very clean condition overall. No major dust or dirt buildup of any kind. Cosmetically it looks very nice, but there are some obvious signs of wear, mainly the 2 holes on the back which were part of a previous tech’s attempt at fitting this unit with the after-market MIDI upgrade. Other than that, all the knobs and parts are present and all look very nice.

The unit was handed down to me directly from Bob. I did some cleaning, and bought brand new ROM chips from Italy. I wanted to do a full restoration, but determined that I liked the unit as close to factory original as possible. I was able to test many of the components, and even the original battery was running at a strong 3V with absolutely zero signs of leakage or corrosion.

Functionally, being as this is such a complex unit, I can’t guarantee any functionality, simply due to the age of the unit. At this time, the unit powers on, all of the buttons and knobs seem to be responsive, and the synthesizer itself is outputting an audio signal that sort of sounds like a constant musical “beat”. I am able to trigger the “Autotune” function, and I can recall saved settings. It seems like the keybed is functioning, but I’m not getting any full “musical” output by pressing the keys (so no notes actually “play”). The only output that’s audible (from all 3 outputs) is that generated tone that changes when you press certain buttons (like waveform etc). All components inside look good and tested fine, which is also why I chose not to rebuild the power supply at this time.

Other than that, the sale includes the nicely padded and very sturdy case. It will be shipped in this case and shipped as is. If you’re not interested in the extra memorabilia, just let me know and I can possibly lower the shipping cost. Shipped exactly as shown in the pictures.

Being as this is such a high value item, I will also need to add at least some form of insurance. This can be discussed between us prior to purchase. Please reach out to me before buying so that we can make arrangements as this is an as-is sale with no returns. I’ve tried my best to describe the unit to the best of my abilities, but sometimes not everything can be described. So don’t hesitate to ask any and all questions. ”

Oberheim Xpander

by

“For sale is an original Oberheim Xpander. This extremely rare synthesizer needs some love. Some buttons get stuck under the front panel, and one of the 3 screens has minor damage as seen in photographs. There are other cosmetic dents and scratches. I do not know how to work on vintage synthesizers and therefore cannot guarantee it’s functioning properly. All I can guarantee is that when you plug it in it turns on and lights up. Ideally, this would be great for someone with experience working on analog synths like this. My guess is a thorough dusting, and some computer cleaner will have this Xpander ready to play. I’m selling as-is. Comes with after market power cord.”

“”Problem:

1. No sound coming out of the phone and other outputs

2. The battery needs to be changed

3. MIDI Channels need to be checked to see if it’s working properly

Action: Verified no sound out of any outputs. Replaced (1) 3V battery. Resoldered the power supply and the contact bridge of the keybed communication boards. Resoldered multiple capacitors and connectors. Performed hard reset. Attempted to reload some tracks from the library via MIDI, but the motherboard did not accept the communication. The motherboard or the keybed scanner could be damaged. Could not find schematics or tech support. Need another unit to compare against to solve cost effectively. The customer decided not to continue with the repair.”” Click here to visit listing on eBay

Oberheim Matrix 1000

by

“An underrated analog synthesizer. 1000 presets of Oberheim goodness. Upgraded the OS to 1.20 for better midi functionality. This synth functions 100%. Does have some rack rash and the rack ears are slightly bent. Also ever since I’ve owned this synth it’s only had 1 screw holding the body together this makes the select button sunk in a little bit. If all the screws were there it would look normal. This does not effect functionality. Selling to fund some new gear.” Click here to visit listing on eBay

“This module has been in a rack since it was first purchased in 1989. It belonged to my relative who was a sound engineer/producer that worked in Roger Troutman studios in Dayton. I took it and placed it in my rack. It has served me well, which I used with my MPC2000, and more recently my MPC One. The sounds are amazing, but I am going away from retro(80’s-90’s) production. Power cord and manual will be included.”

Oberheim Matrix 1000

“I bought this Matrix 1000 and a Matrix 6r over 9 years. They both worked perfectly fine with all the presets and sounds working great. I plugged both of them back 2 years ago and noticed that they were no longer working as well as before, losing their original power and now both are barely getting a signal. I talked to a local synth repairman and he told me to change the battery and firmware. I honestly never got around to servicing these machines, so I am letting them go for a very fair price. This (Matrix 1000) comes with the power cord and a new firmware chip as shown in the pictures.” Click here to visit listing on eBay
