“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.” Link

“Super Rare: Oberheim OB-1 Synthesizer. The Heaviest sounding monophonic synth …Ever. Programmable memory locations where you can store your own settings. There are 2 oscillators – but each has a sub-octave which really fattens things up. Includes Genuine Oberheim VCF Pedal, Oberheim Cassette Interface and cable for additional memory, Original Patch Book, Instruction Manuals for Cassette Interface and Synth, Schematic. Wow! You will never see another set like this. Ever”

“Good Condition and recently gone through by a local tech who also installed the a new

Tauntek programmer with the following updates:

A new MCU-based programmer pcb is now available for the OB-1

I have designed a replacement for the Oberheim programmer with the following features:

1) 64 programs in 8 banks of 8

2) Programs are stored in non-volatile EEPROM. No battery needed.

3) After a program is loaded, only controls that have moved are “live”, so patch editing is now possible.

4) Manual mode forces all controls to be “live”.

5) Optional (non-volatile setting) periodic flash of current bank selection

6) Optional (non-volatile setting) quantization of coarse freq for oscillator 1 to octaves

7) Comes with 24 pre-programmed patches, which can be over-written later if you chose

8) Smaller pcb mounts on four of the existing standoffs, providing better access to pcb underneath

9) Implemented connectors are the same as original programmer for easy installation

10) All IC’s are socketed. All components are through-hole.

11) 20-turn trimpot for easier one-time oscillator tuning adjustment

More info at tauntek OB1 site

I installed new key bushings as well in the last month.

Outer case has some blemishes and surface rust here and there, but in overall good cosmetic condition.

Pretty rare piece and would make a great addition to your studio or collection.” Link

“I have too many synths so I have to make room! This guy is amazing! The sounds that come out of this are SUPER musical! Its a true analog synth which has analog oscillators which are controlled digitally. Very advanced for its time. This unit has a reputation and it deserves it. It is monotimbral and polyphonic. It can play 6 notes max simultaneously. You wont need that many notes to create powerful sounds! For the best programming experience, if you want to program your own unique synth voices, I highly recommend midiquest pro. I havent found any other editors that work as good as that one. Its available online. But as the name states, it has 1000 sounds already onboard, so just browsing through all those, you should be able to find something very close to the sound you want and then modify it to your liking. It sounds so beautiful… It has midi in/out/thru, Mono 1/4″ Out, and the power cord is included. The rack ear on the right is slightly bent as you can see in the picture but it doesnt affect the functioning in any way.” Link

obie-1” Bought this in 2003. Excellent condition. Used in my home studio only-temp controlled, no smoke. Have a lot of synths that I don’t play much, so time to pare down and keep only my most used ones.
Everything works perfectly, including the memory, EXCEPT…
The only problem is the OSC 1 Pulse setting doesn’t work. There is one knob to choose between Saw on the left and Pulse on the right.
No go on the right. It came this way when I bought it. Seller didn’t disclose this fact, and I didn’t make an issue of it (maybe should have). It doesn’t really affect anything in the overall scheme of the sound design. With OSC 1 on Saw, you still get that analog Oberheim sound that’s quite distinctive.
I’ve always loved the big sound and versatility of the OB. I also have a Moog Voyager, so that will be handling alot of the sounds the OB can do, but of course, it’s not an Oberheim.” Link

Noise and VCO 1 OCT appear to function and all other controls have an effect on the sound. All keys sound but will need cleaning. No battery is in the unit and i am unsure if the PROGRAM section will store/retrieve your 8 personal presets.” Link

” Oberheim OB-1 vintage analog synth
One of the first serial number 0038.

The pitch bend lever is unstable and should be looked at.
It fluctuates a bit and when you let go of it, the pitch stays up about a half step
you then half to jiggle it for it to return to proper pitch.
This only happens in the Broad position. The MOD and Narrow positions function properly.
(there is a 3 position switch for bend routing)

Everything else appears to be functioning properly.” Link

“vintage oberhiem ob-1 with a low serial number of #328 Great physical condition. The memory battery looks to have been replaced at some point and was just checked and was at a fresh 3.6v. It is not a solder in battery, it’s in a factory holder like it should be. no corrosion in the battery holder. This keyboard was a one owner before i purchased it last winter. This keyboard saves patches and both sections analog and the patch memory digital section work great. I love the touch sensor capacitance switches. It should be noted that the knobs with grey tops don’t save into patch memory per the oberheim owners manual (available online,) so you do have to pay some attention to where the knobs are pointed if you’re looking for an old analog preset synth. This thing was way ahead of it’s time. Which is the reason it was used by some of the greats. Geddy lee was the biggest name who used this and there were only a hand full of the two mki and mkii models made.

Less than 500 of the ob1. Please note the difference, this is an original OB1. Not the ob1a that sell for less because they made more.” Link

“I really hate to sell this one as I searched for it for so long, but sadly it has to go to make room for other equipment.

I’m selling an extremely rare Oberheim OB-1 Analog Synthesizer. For those unfamiliar, this is a monophonic synthesizer and was among the first synthesizers to offer the ability to store presets. The unit can store 8 presets at one time using battery backed memory.

This particular unit has recently been calibrated and has had a new battery installed. Everything seems to be working great, although there may be the occasional crackle from a potentiometer.

The only issue that should me mentioned is that this OB-1 at one point was modified for use with some kind of sequencer. The modifications have been removed but there is a small hole in the front where a toggle switch had been mounted and a 1/4″ hole in the back where a jack had been mounted. Both of these holes can easily be plugged. The front hole had been marked and the legending should be easily removable. There is also a balanced output installed to the back with a balancing transformer.

The unit is in quite nice shape overall with minimal marking on the metal, as shown in the pictures. There is a little scuffing on the wooden end caps. See the pictures for details.” Link

This was the very first synth in its class with programmable memories (eight touch-sensitive buttons) and is in a similar class of sound as the SEM but with more programmability and features. The synth was recapped a few years ago and recently checked over, and all functions and patch storage work perfectly. The keys are all level and the action is great. ” Auction ended.

CASS-1, OB-1, Oberheim @ 10 April 2012, Comments Off on Oberheim OB-1 with CASS-1

“For sale is a Oberheim OB-1 Vintage Synthesizer. It also includes the very rare Cass-1 Interface box.

Cosmetically the OB-1 in excellent condition with very little wear. Has some light marks on the wood sides and also has some small specs of red paint beside some of the knobs. I’m guessing a previous owner has put them there as preset markers. Some of the red specs were also removed at one point leaving some faint scuff marks in it’s place. Both the red paint specs and scuffs are very minor and not really noticeable. (see photo as an example)

The Cass-1 Interface is in mint condition. It includes the original connection cable and original owners manual. The purpose of the Cass-1 Interface is to back up the memory presets onto standard audio cassettes. The Cass-1 Interface is also usable with the Oberheim 4 and 8 voice poly synths that are equipped with the memory presets panel. It’s a very useful interface box for creating and archiving a sound library which you can load and save into the synth.

Both the synth and interface have been tested and are fully working” Auction ended. Click here to browse on eBay.

” Up for auction is my low serial number Oberheim OB-1 monosynth. When I was last using this synth regularly, it would play absolutely marvelously.. However, after being in storage for a few years, it is once again in trouble:

When powered on and a “program” selected, audio output is extremely low. There’s two audio outs on the back, low and high. High is audible, and low I couldn’t hear at all. I tested all of the knobs, switches and keys, and all work. As it’s so low in output it is hard to say about the overall tuning, but the oscillators and filter still track to the keyboard.
One key is slightly lower than the rest- the D3

Because of these issues, I’m starting this auction at an extremely low price with no reserve.

This synthesizer is serial number 0058.

Back in 2005, Kevin Lightner (synthfool.com) completely restore this particular synth. It was in heavy use until 2009, at which point it went into the studio closet.” Auction ended. Click here to browse on eBay.

“Up for auction is an Oberheim OB-1 in as is condition. I played around with it for a good week or so and have assumed the VCF and VCA envelopes to be non-functional. In other words, if you turn it on and press a key, the sound will play just fine but not stop. If you tweak any of the VCF or VCA knobs there will be no effect on the patch. In addition, the second A key does not work. From my judgement there doesn’t seem to be anything else non or semifunctional with the synthesizer but I could be wrong. In addition I did not test any of the jacks besides the audio out. Again, this unit was played for about a week while I sampled what I could and all knobs and buttons besides those in the VCF and VCA groups seem to be working fine. ” Auction ended.
