“This is a working 5 voice Oberheim OB-SX synth.
New bushings were installed and the keyboard leveled.
The synth needs some attention. Some double triggering, keyboard contacts should be cleaned to help resolve this. Synth should also be calibrated to keep in tune better across the keys. The power button light stays on even when switched off. Strange, though it doesn’t affect anything. Several screws missing from end pieces.
All buttons and switches appear to be working, though I’m not sure what “Narrow / Broad” switch does, I didn’t hear a difference.
“Hold” and “Chord” buttons work by holding a key, then pressing “Hold” then “Chord.”
I typically turn on synth, wait a few minutes, then hit “Auto” in order to tune. As stated, it needs calibration to be in better tune, but there are plenty of sounds that play wonderfully as is. See videos.
This Oberheim is being sold “as-is” with no returns, due to its vintage nature and commotion during shipment. Get it tuned up or use it for parts for another Oberheim.”

“This is a previously used Oberheim Matrix 12. The Matrix 12 comes straight from our professional recording studio and is in excellent shape. The synthesizer was recently cleaned and serviced giving it longevity and peak performance. The only cosmetic wear you will find is on the wood side paneling, most notably on the left panel; the wood is partially chipped. Overall, this Matrix 12 is in very clean condition and is a prime example of a legendary synthesizer.”

“Oberheim FVS-1 Four Voice Synthesizer
This is a great example of a four voice. This unit was restored recently, with rebuilt power supply and decoupling caps replaced on all boards, pots cleaned, keyboard bushings replaced and entire keybed cleaned and polished out, and oscillator tracking calibrated.
It plays and sounds incredible. Only issues are that the master volume pot is a little scratchy (only when adjusted), and memory store/recall does not work properly despite replacement battery. Memory storage on this keyboard is not very useful anyway – since some of the most important settings cannot be stored with a patch by design (modulation routing, etc.). The more useful features of the optional programmer module all work perfectly (vibrato, centralized pitch, filter control and envelopes). Tolex is original, and some bumps, bruises and rips have been professionally touched up (worst of it was on the lid).”

“Even after more than four decades after its introduction, the Oberheim 4 voice is still a beast! That’s why I’ve always wanted to own one – ever since I heard 4 independent voices (2 oscillators per voice) almost blow my head off, back in the day… I had never heard anything like that before!
This was going to be one of my great project synths in retirement. This was going to be one of my signature analog synths in my project studio. I said “was”…
I’ve had it now for over a decade since I acquired it and its been kept in the studio storage closet, waiting for its time to be brought roaring back to life. When I bought it, the previous owner said to me “it had some problems”. He wasn’t specific at all. I remember that it did power up though. I did not hear it generate any sounds though…
I’ll admit, new computer software emulation programs has made me lazy… Now I just click on a emulation program if I want to experiment with a certain sound. It’s sad… but true. The journey of discovery by creating with a real physical synth using knobs and controls has been paved over by a freeway of mouse clicks and drag and drops. Progress, I guess…
Needless to say I’m not going through with this project. It’s time to move on and turn it over to someone that has the desire, energy, financial resources, time and patience.
These instruments have withstood the test of time, as cumbersome as they may be to program. But it’s really no different than a Moog Modular, Arp 2600 or other synths of that generation. That’s the joy of working with these classic synths! It takes solid effort and determination to discover the sounds that are unique to your music. In other words it takes work! These instruments will continue to be serious tools for music composition by their intrinsic design and by the very nature and essence of their sound. Whatever genre of music that came out of the 70’s and 80’s – from rock, jazz, pop or electronic, you’ll hear an Oberheim. Nothing else sounds like an Oberheim! This instrument deserves a home where it will be preserved, used and appreciated for decades to come…
It is being sold as-is, “for parts or not working”. ”

“Getting rid of almost all my gear.
Quite possibly the most fat analog synth ever made
Only known issue is one of the 8 voices is out of tune.
Physical condition is great for a synth this age. A couple of scratches. Nothing major. If you want more detailed pics just let me know. ”

“Purchased second-hand about 10 years ago.
Take it out about 10 times.
There is no problem with either of the MIDI sound control.
Fine scratches and paint peeling on the wooden side panel (3rd image), deflection on the front panel (4th image) and cello tape mark (5th image), small chip on the VCO1 switch (6th image), rear panel There are two stickers applied (7th image), but I think there is no problem with the performance.”

“Vintage ’80’s Oberheim DX Programable Digital Drum Machine. This drum machine is an early version and does not have MIDI. The overall condition is very good while showing some wear from age and use. All buttons and sliders are in good working order. The original samples sound great and each one can be tuned using the back controls. We were able to record some drum patterns and play them back. We did not try interfacing a cassette, so those functions were not tested. Includes an AC cable. Sold as-is. ”

” (**IMPORTANT! THIS MUST BE PICKED UP IN WEST LOS ANGELES, CA. ONLY! CAN NOT BE SHIPPED! BUYER GETS ADDRESS AT END OF AUCTION. IF YOU CAN’T PICK UP, DON’T BID!**) WOW! You don’t often see these babies for sale…. A VINTAGE 1983 original OBERHEIM OB-8 keyboard SYNTHESIZER! With a pedigree you won’t believe! And I tested it out, first time in 25 years and it SEEMS to work fine. This beauty has NEVER been used by a band on the road. Was treated really well since 1983. Never banged around and was always covered with a blanket.
Hasn’t been used in literally 25 years. Having been stored away safely in a cold dark closet since 1994, this belonged to infamous supergroup/duo BARNES & BARNES! The “FISH HEADS” guys! They got this early model, which had just come out, back in mid-1983. Was used on their “Soak It Up” ep, all the way up to their Dinosaur Album in 1994, then they only used “digital” synths pretty much from then on. No one knew that 25 years later, THIS would again be the COOL old synth to own”

“Powers on when plugged in. In great to excellent condition. I used it in my music studio years ago. Unfortunately, after a year, the studio had to be torn down. The building was to be gutted and this unit, along with all of my other studio music equipment, have to be stored away – they have been cleaned, wrapped and stored away in a storage unit until now. I have not used it again since I packed it away, and now I am moving out of the country soon. Thus, I am selling as is.”

“This sample player is the classic Oberheim DPX with a mono output and two floppy disk drives. We tested the unit and it worked properly at first, but the output started to crackle and fade out after about 15 minutes. We loaded a number of disks and were surprised at how many worked – out of about 15 disks, only one didn’t work, and another needed some TLC to load. The issue with the unit seems to be the audio output side, and it will require a tech to troubleshoot and fix properly.
The real gem in this auction is the huge collection of classic samples on floppy disk. This collection belonged to my best friend, who sampled and played the “I Need You” sample on the 80’s Stacy Q hit song “Two of Hearts”. They are in various formats*, and many are Mirage format disks, with some amazing, now impossible to find, library samples from the 80’s such as various K-Muse sample disks, as well as one-of-a-kind samples by my friend. Again, we didn’t test all the disks because of the audio problem, but of the ones we tested, most loaded and worked properly. I counted plus or minus 340 sample disks plus a stack of random non-sample disks I pulled out of the collection (see photo). Auction includes the briefcase to hold disks.”

” Oberheim Matrix 6R Rackmount Analog Synthesizer Excellent Condition. I have had this for about 15 years and almost never used it. Everything is functioning well and cosmetically it has very little wear, looks almost new other than small scratches only visible in bright light. No visible rack wear. You’ll love the analog sound of this if you’re used to using plug-ins or other digital sound devices. It’s got the sound of 80’s analog and the unison bass patches are huge sounding. Unlike the Matrix 1000, the 6R has earlier model chips and has front panel programming. Tom Oberheim said he liked the Matrix 6 series better than the Matrix 12 for pure sound quality. Has thick rubber feet so it can be used table-top or racked.”

“What we have here is my old Oberheim Matrix 6 synth that my dad bought me new back in the mid ’80’s. It plays, sounds and looks good for it’s age. There are a couple of scratches and dents here and there. Over the years, I’ve replaced a couple of broken keys but have had no other repair work done. The volume fader can be a bit scratchy and the output jack can sometimes be a little touchy. As far as I can tell, everything else works well. The factory patches are loaded and software version is 2.13. Many other patches are available online for free. I’m still looking for the manual, sustain pedal and additional patch cassettes. If they tune up, I will definitely include them.”

“Oberheim OBXA, the Van Halen “Jump” Synthesizer, and king of 80’s brass strings and pads.
This fine vintage instrument was recently professionally serviced (March ’19) by world-class synth technician Greg Montalbano of Analog Synth Service (Oakland, CA). This service included keybed maintenance, and voice tuning/calibration (records available).
Cosmetically, an OBXA in Excellent near-collector grade condition, with the 120 patches, and the more desirable Pratt & Reed keybed, is pretty rare! It’s mostly clean, with a couple slight scuffs/scratches, and small chip to left wood side. See pictures for details.
Synth will be well-packed and shipped. ”

“I have had this matrix 6 for at least 10 years. I don’t really want to sell it, but my car needs the transmission rebuilt and as you may know that is expensive. Something has to go!
If you don’t know anything about the Oberheim Matrix Six, it six has that sweet analog sound that everybody wants, six Oscillators and full midi capability. velocity and pressure sensitive keys. This is an undervalued gem, grab it while they are still affordable.
It has been upgraded to the newest firmware, everything worked great when I put it away. Brought it out to sell and everything still works great as far as I can tell, I can select patches with the keypad, I can play music, and pleasing sounds then come out of my speakers.
Comes with what I believe to be the original foot pedal, a power cable, And the heaviest duty keyboard case I’ve ever seen, it is a tank! Unfortunately the foam is deteriorating, so you’ll have to re-foam it before you can really use it. I will ship the keyboard in the ATA case but will use extra bubble wrap inside to protect it since the foam is falling apart.”

” This synth has seen light use in my studio and was never toured, however I am not the original owner.
The physical condition is 7 of 10. Some of the finish is worn and faded, and the sides have a few dings and dents. All pots, knobs, faders and ports are in good condition.
Functionally, its 8.5 of 10. As you can see, the synth passes a tuning test and appears to function without obvious issues. That said, this is vintage gear — tuning is a bit unsteady, needs 20+ minutes of warmup before use, occasionally a button might need to be pressed twice — you get the idea. But all outputs work, and it sounds DIVINE. ”
