“Oberheim OB-8 Keyboard Synthesizer With MIDI. Has Issues, Sold AS IS No Returns. Problem(s) possible in DAC circuitry or S/H. Voices 4, 5 & 8 won’t always tune. Other voices seem fine. Needs a proper calibration. In great cosmetic condition. MIDI and all other functions such as the panel, pitch bend and CPU operation seems fine.

“In great working condition vintage Oberheim DX drum machine, everything on it works all buttons,outputs and faders no doble triggering issues. The pitch knobs are located in the back unlike the DMX which has to be open every time you want to change pitch on the voices. There are some scratches on the side panels and a cpl of scuff marks on the front but overall in great working condition for it’s age. This is the early edition dx so it doesn’t have the midi option, includes original power supply and hard to find original manual..” Click here to visit listing on eBay

“This Matrix-1000 synth module is 100% functional and it sounds wonderful.
All switches, pots, jacks, and LED display work exactly as they should.
Cosmetically, it is in outstanding shape as the pictures show. There may be a couple of barely visible scratches, but that’s it.
This Matrix-1000 interfaces with my Korg Triton via MIDI. Depending upon the patch, it responds to both keyboard velocity and aftertouch.
I have used my personal computer, MIDI-OX, and a windows-based librarian to download and modify patches. I have never experienced any problems.” Click here to visit listing on eBay

“This auction is for an Oberheim DX drum machine. This unit has sat in my closet for 15-20 years. It does power up. However it come up with a CASS error on the display. Talking with someone who works on these it may just be a battery. I cannot confirm this. The symbol prom needs replacing, it makes a car crash sound and has done so since I bought it. It is around 40 years old, needs cleaning and has stickers on it along with missing a slider knob. Comes with power cord. Unit is sold AS-IS.” Click here to visit listing on eBay

FVS-1, Oberheim @ 07 August 2018, Comments Off on Oberheim FVS-1

“Up for sale is my Obie four voice FVS-1 polyphonic synth ca.1976. I’ve owned this for about eight years, and it was serviced in 2011:

Keybed was completely disassembled, cleaned, keys polished out, new bushings and leveled. This is the silkiest Pratt-Read you will ever lay hands on!
Power supply recapped, and all tantalum decoupling caps throughout were replaced with high quality electrolytics
All open frame pots, jacks and trimmers cleaned
Entire unit cleaned inside and out, and tolex was touched up (lid is a bit rough, but lived in storage; still some scuffs visible on base, but very presentable overall)
Several chip replacements. Some preemptive (LM324 CV buffers in the programmer) and some to resolve faults (CMOS in keyboard controller). Quality machined pin sockets were installed
Amber LEDs installed throughout (just because…)
It had two holes in the top rail of the case, and I repurposed those with mini toggles to control routing of s/h and filter mod from external MS-1a (not included). One hole on rear patch panel was plugged

All functions work great, with only exception being the patch memories – VCO tuning across the SEMs is not consistent when a patch is recalled (tuning is fine under manual operation). I never got this addressed, as I tend to not use the patch storage. The memory is pretty useless on the FVS anyway, as modulation/switch settings cannot be stored with the patch. All other functions of the programmer work perfectly (e.g. global envelopes, global quantized VCO tuning, global filter controls, LFO, etc.; the real value of the programmer module IMO). The master volume pot is a bit scratchy (sealed pot; could not clean). A few of the plastic caps on the VCO fine tuners are missing, as are two mounting screws on SEM #4’s front panel.

The good news is that other than the minor nit-picks above, the synth sounds and plays outstanding! Having four SEMs under polyphonic control is a mind blower. I will miss this synth dearly, and I’m sure I will kick myself later. I just don’t have the time to give this the use it deserves these days, and hope to find it a good home.” Click here to visit listing on eBay

Matrix 6R, Oberheim @ 31 July 2018, Comments Off on Oberheim Matrix 6R

“This Matrix 6R is great, I hate to part with it. Compared to any new Dave Smith Instrument this blows them away in my opinion in terms of fatness and tone. They really don’t make them like they used to. Get that creamy Oberheim sound on a budget with this highly underrated synth. This has lived happily in my smoke free studio, aside from some rack rash and a slight knick here and there its a great rack synth and won’t disappoint.” Click here to visit listing on eBay

Oberheim, Xpander @ 31 July 2018, Comments Off on Oberheim Xpander

“Selling my beloved Xpander as I am moving studios and need to drastically downsize.

It is a wildly flexible and lush instrument, going from Steve Roach to Nine Inch Nails and everywhere in between.

It has 5 LFOs and 5 ADSRs per voice and a computer controlled patching system that has clearly influenced just about every semi modular VA ever made, hardware or software. In terms of modulation and multi-timbrality it can do very interesting things. I like the sound of all the filter types and the oscillators. It is a beautiful sounding instrument.

The Xpander has worked great for me, and it passes the tuning/servicing test for all voices. Please refer to the images.” Click here to visit listing on eBay

This US manufactured version of the Oberheim Xpander (far superior in build and component quality to the later Japanese ones) is in full working order and been in a smoke free studio with good temperatures in my ownership since 2015.The only evident defect is that the front panel is slightly faded with age (see photos). ” Click here to visit listing on eBay

“Vintage Oberhiem DX Drum Machine all functions, buttons, and sliders tested great. With power cord, full manual is downloadable for free online. I’m not sure about any expansion roms, but it seems that there are some extra chips and possible board enhancements through comparison with pictures of other units. The “DX sync-to-tape” board for instance is not inside any other unit I could find pictures of online. That’s not to say it wasn’t factory standard, i just don’t know if it was or not.” Click here to visit listing on eBay

OB-8, Oberheim @ 17 July 2018, Comments Off on Oberheim OB-8

“This is an early model Oberheim OB-8 analog synthesizer from late 1982 and “Does Not” have factory MIDI. It has a small dent in the rear of the unit shown in the photos. Program 5 led is slightly brighter than the rest, one of the reasons for the lower price point. It looks like it was replaced before I owned the unit. I have it for almost 10 years and never had any issues. The same led comes on very dim when program 1 is pressed, please see the power on photo, it is hardly noticeable. My studio is well lit and always thought it was because the led was newer. All the programs work great! I do not ship internationally and only ship to the lower 48 states. If you have any questions please contact me. I will consider any reasonable offer. Get it while you can! Somebody “will” get this big boy if the price is right! They are selling for over $4k and the MIDI kit is cheap if you want to upgrade. I never had the need to use MIDI. It’s a super performance and recording keyboard, especially if you like Rush and Van Halen or other groups that used this type of keyboard!” Click here to visit listing on eBay
