Oberheim DX

“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. ”

Oberheim OB-8

” (**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”

Oberheim Matrix 1000

“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.”

Oberheim DPX-1

“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

” 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.”

Oberheim Matrix 6

“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 OB-Xa

“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. ”

Obehreim Matrix 6

“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.”

Oberheim Xpander

” 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. ”

Oberheim SEM

” For sale is one of the all time greats of synth sound and history…

Vintage Oberheim SEM module! 100% working. Face is in great shape!!!! All knobs, functions work great. The housing shows wear (bottom and sides). The output for low was modified to 1/4 inch. The unit appears to have been recapped properly- the original tropical fish caps are still there (never swap them unless you MUST… you will hear a difference) There has definitely been some work done inside- the 1/4 mod, recap, some wiring looks non original. BUT I always took it as it was serviced. The unit sounds and performs as it should but it has NOT been calibrated. Assume drift.

It tunes awesome and HOLDS tune, unlike my Minimoog LOL… which btw it was MADE for. As an expander for a mini, its ridiculous. And theres a mod you can do on your mini for CV out and you can control it from the mini!!! (It was called the “S”ynthesizer “E”xpansion “M”odule LOL) Thats how I’ve been using it and it kills. But I’m so tired of multi tracking chords note by note LOL!!!!

This is an actual SEM not a rehoused module from a 2, 4 or 8 voice.”

Oberheim OB-X Project Machine

“Not a common synth to find on Ebay – there is one on Reverb for 10K

at the moment. Holy Grail for you vintage analog synth buffs. Dates to 1979.

cosmetically very nice, has a couple scratched keys and some normal age but

faces up well and not missing or broken knobs. Serial Tag on back stamped 6 Voice

I know these came in 4, 6 or 8 voice. no too many of this model made

Comes as seen, Please see all pictures. I too pics of the inside as well so you see exactly what you are getting.

powers on, some of the LED on the buttons on the left side just blink but the unit has No Sounds / output

all keys are there and move – not damaged – a couple are scratched.

Quite a rare unit and well worth the investment of having it brought back to life

I do not know a Synth tech that I can trust with this unit so I will leave it to you to

get it done right!

Since it will need service so it will be sold AS – IS No Returns”

All buttons on the interface and the display were tested and were good (I plugged in the interface board into a working unit to test). So it appears that the problem is with the main board. Not sure it can be fixed. May be better off used for parts as the control board is in great shape.

Oberheim Matrix 6

“Up for sale is the legendary oldie but goodie,oldie but basically like new goody if you can believe it. The Oberheim Matrix 6. Yes im talking about a basically untouched classic piece of vintage gear in basically new condition !!, This piece has never been serviced, repaired or never even been played for more than even a few hours in TOTAL. So in other words its basically like walking into a Sam Ash or other music store between 1984-1987 an asking “may I please have a Oberheim Matrix 6″. I was thinking about keeping it as a show piece because of its age and history, and not to mention it is sort of a family heirloom, but I need to buy other gear, I have shown numerous pics in this posting but if you require additional pictures please don’t hesitate to ask, and that goes for any additional questions too. Included is the original foot pedal and power supply, sorry but I don’t have the manual,”
