“100% working. Normal scratches and scuffs, but no major damage. I think the LED window was once loose and is taped to face plate from inside. Original 1.11 firmware. Likely original battery that will need eventual replacing. I have owned this synth module since the late 90’s and it’s always been stored in climate controlled smoke free environment…and used very little during my ownership.” Click here to visit listing on eBay

“Used Oberheim Matrix 6 keyboard with the following included: power cord, foot pedal, manual, sound patches cassette, some midi cables and travel case. The unit will be shipped in the travel case along with all of the mentioned items in the case front pocket.

I tested the unit and all buttons are in working order. All output jacks are working. All keys (black and white) are working. Both shifters are working. Volume control is working. Did not get to test the MIDI jacks.

Due to the age of the keyboard, I must disclose the following items.

•The display is not working properly. I did some research and I believe that a battery may need replacing.

•Minimal body scuffs but there is one dent in the corner top of the keyboard. Does not effect the play of the keyboard.

•And finally, the foot pedal does not work properly. Not sure if it is the pedal or the jack. It may be a setting on the keyboard that controls the foot pedal but with the display not working properly, I could not figure it out. The foot pedal is sold as.”

OB-8, Oberheim @ 01 May 2018, Comments Off on Oberheim OB-8

“This sale is for a vintage Oberheim Ob8 8 voice polyphonic analog synthesizer with factory midi. It’s in excellent cosmetic and working condition. It’s been cared for lovingly in a smoke free studio.

This particular OB8 was previously owned by Earth Wind and Fire, one of several they owned. After Maurice White passed, one of their techs was tasked with selling their extra gear; this was part of that sale.

the only reason I’m selling, I don’t use it much and would rather use the money than have it sit idle.” Click here to visit listing on eBay

“Regretfully selling my oberheim dmx drum machine, very clean, smoke free studio adult owned. Had this for almost 20 years, comes with manual and power cord. Was in my studio #2 for years and recently just been sitting on a gear shelf after my move. Used to work and play just fine , but when I recently just turned it on the screen is blank. So I have to sell it as a parts only auction. Very clean check the pics. This thing is a legend for a reason !” Click here to visit listing on eBay

Oberheim, TVS-1 @ 03 April 2018, Comments Off on Oberheim TVS-1

“This is the original vintage 1975 synth, with an extremely low serial number, not the reissue. It’s unlikely you’ll find another currently on offer in the USA, and very unlikely you’ll ever find one in as good condition.

100% fully functioning. Recently serviced and calibrated in late March 2018 by Nick Montoya of Moog Music. This is one of the finest examples you’ll find.

The only cosmetic imperfection is a small, light scratch above the volume knob, and on the outside of the case, there’s are a couple of small tears. It looks almost new.” Click here to visit listing on eBay

“Appears to power up and work fine. I don’t have another Oberheim synth to connect it to so I’m unable to test it. Was told it works fine. See photos of inside. Some corrosion near caps at front of bottom PCB. Power cord not included (it’s just a regular PC cable).

When you turn it on it says “CONNECT SYNTH” based on some googling that means it’s version 2.X or lower.”

Matrix 1000, Oberheim @ 27 March 2018, Comments Off on Oberheim Matrix 1000

“This is the great Oberheim Matrix 1000, with 1000 pure analog patches. This synth packs so many sounds, it can be overwhelming. I’m also pairing it with an Alesis Qudraverb. The two together are perfect for most synth needs. The Obi works great but the volume pot is a little scratchy, I used it mainly with my Keystep for a year or so, and only in my house. From what I was told it is all original and no mods or updates have been done. Not sure if Ive gone through every patch, but the ones Ive used sounded amazing. Quadraveb is in decent shape, Ive noticed that if you move it around alot the output can cut off, but is not really an issue for studio usage.” Click here to visit listing on eBay

“Near mint condition. I cant find a scratch or fault anywhere on this Xpander. Looks brand new without a flaw. Functionally, works flawless. All encoders work properly with no skipping or errors. The LED screen works perfect without any burned out lights or faint lit lights. All 6 voices tune properly. Wooden side panels look new-screws look new, etc, etc. Maybe the underside of the Xpander is scratched….I haven’t looked at the bottom. Roadcase is in very good condition-interior foam is in excellent condition. Original manual is in fair condition. ” Click here to visit listing on eBay

“Greetings; I’m offering up my Oberheim DSX Sequencer. It comes complete with the foot switch, volume pedal, power cord, and interface cable. This DSX has been stored in a closet at my home for many years. It is in excellent condition for its age. I sold my OBXa many years ago, so I have no way of testing it properly. The DSX worked well with my Obie before I stored it, which was 10+ years ago. My OBXa had the MIDI conversion, so I didn’t use it too much….(I was using a Roland MC-80). I’m not sure if it needs to be serviced, but the battery will most likely need replacement. I will include the instructions if I can ind them. I’m not too far from most of SoCal if you would like to arrange for pick-up” Click here to visit listing on eBay

OB-1, Oberheim @ 27 February 2018, Comments Off on Oberheim OB-1 Project Machine

“Purchased in 2002. Very clean condition. There is no pulse wave on VCO 2. It came that way when I bought it, so I just leave it on Triangle which sounds just great. The manual says you can vary the slope of the Triangle waves, but I have never been able to do that. You can vary the pulse wave on VCO 1. Everything else works great. Two sub oscillators to create a really fat sound, plus cross mod and sync to get some very interesting sonic explorations. These synths are quite rare and not up for sale very often. They are direct descendants of Oberheim’s SEM modules. A true piece of synthesizer history.” Click here to visit listing on eBay

Presets all seem to work as do all the led switches. The case does have a few light scratches, but there is nothing broken that I can see. If your local, please come and try it out. I do pack very well and will do my best to get it shipped to you with no damage. I will be listing more items soon. Thanks for looking at my auction.” Click here to visit listing on eBay

“Oberheim Matrix 6R rack mount synth.

A matrix 6 in a rack mount!! Good condition.

Amazing sounds. Huge-even.

Typical rack wear, but it has been well maintained.

the power supply was recapped a few years ago.

we did it just to be safe.

This works perfectly, operating system is 2.1.3

I think I have a file with stock sounds that I can send or burn to a disc.” Click here to visit listing on eBay

I think I have a file with stock sounds that I can send or burn to a disc.

I do have many of the stock sounds slightly altered to use a midi cc controller for cutoff and resonance.

What this means is that many of the sounds currently loaded don’t really make much noise until you give your midi knobs a little tweak.”

“For sale is an Oberheim Matrix 6R from my personal collection, owned for many years. Hardly used and kept in smoke free home studio. Fully functional. It’s in good shape, it does show some signs of wear as expected for its age. The only issue worth mentioning is its missing the cap for the slider shaft, but the slider is still there in tact and working as it should. Check out the pictures to make sure you like it.” Click here to visit listing on eBay

“Classic rack mount version of the Matrix 6 synth. 6 voices of Oberheim analogue 80’s goodness. There is one small segment of LED on the far right which does not light up, otherwise it’s working perfectly and sounds fantastic. It can run on either 120v or 240v by swapping a fuse (it is currently set to 240v). Happy to pack well and post.” Click here to visit listing on eBay
