“Arp Omni I — Original 1975-1978 classic string synth. Powers on. Keys feel pretty good, sliders are not too gummy, all push buttons depress correctly and the respective LEDs for those buttons light up. I was not able to get the unit to produce sound — only static produced from the low output” Click here to visit listing on eBay

“This is a non working arp omni 1.

We had a technician go through it and he replaced the caps, rebuilt the power supply, and replaced some of the ic chips as well. After this the unit would not pass audio. Not sure why at this point.
The synth is sold for parts or repair. As Is. ”

” This is an Arp Omni I from the 70’s. It sounds phenomenal. This unit was fully serviced 2 years ago, and brought up to spec – every electrolytic capacitor in the synth was replaced, all of the slider switches were cleaned etc. Since then, I’ve only used it my studio.

I went through everything and it works perfectly with exception of the attack slider, which seems to do nothing and is set on a fast attack. This is probably an easy fix. Other than that, as far as I can tell, every button, slider & key work properly. Some of the sliders are missing the top piece and there are some markings on the top of it. Please see photos for the cosmetic condition.” Click here to visit listing on eBay

” The Arp Omni is a 40-year old vintage synth now prized for it’s string sounds. This unit has been in storage for 20 years, but unfortunately only powers on, does not produce sound. Attempted to clean slider pots and installed ~30 new capacitors, but not expert enough to fix the unit.

What’s included:
– the Omni itself
– custom canvas case
– original owner’s manual (cover torn but the rest in tact)
– original spec sheet
– collector’s special–the original 33RPM vinyl demo record and accompanying poster

If you’re not an expert technician and know this model i would not recommend purchasing this—the solder joints appear to need rework by a professional, and this model requires specific knowledge and parts to repair. That said, once working, these are now rare and command a high price.” Click here to visit listing on eBay

usedmom “Arp Omni 2 Model 2473 for parts / repair (with Anvil case)

This is a non-working Arp Omni Mark 2! It is complete as far as parts, keys, components, etc. are concerned, and is only missing the pot slider caps.

This unit doesn’t play a note! It is purely a “fixer upper” or useful for parts. It does power on, and all lighted switches turn off and on… but the most it does right now is produce the infamous electrical clicking noise (through the “SYNTH,” “STRINGS,” and “BASS” outputs) when keys are pressed, followed by a faint click noise when those keys are released. Physically, it is in decent shape for its age, with the expected scratches and dings here and there from transport; the control panel, sliders, buttons, and keys are all good; no keys are chipped, and they are fairly even across except for two or three [See pictures.].

The blue balloon tantalum key capacitors were all replaced several years ago with electrolytics. The power supply tantalum and electrolytic capacitors were replaced with new electrolytics as well. The phaser circuit board and other electronics are all present.

If you have a good tech—or a fair amount of free time of your own—this could be a worthwhile project. (My studio unit is identical to this one, and it is one I bought non-working for cheap and fixed up.)

Arp Omnis are great synths: they offer a nice set of analog string sounds, a basic synth with simple, changeable parameters, and a bass section as well. All of these can be combined, too. Plus, there are two on-board effects: a phaser and a “wave enhancement” feature, too, which does _____ that makes things sound real cool…. Finally, the Omni is polyphonic through divide down circuitry (except for the bass section when it is activated; I think that is low note priority monophonic if I recall correctly).

The Anvil case is missing the original foam (which I removed because it had decayed into uselessness), but the Arp will be wrapped in a new foam mattress cover/pad… which will have the same cushioning result.” Click here to visit listing on eBay

used-omni “The most awesome ARP Omni 1 ever! This synthesizer has just been fully serviced by Synthchaser, the west coast’s leading ARP specialist – recapped, new bushings, LED sliders, fully functional, calibrated, tuned and sounding great. This keyboard is the sound of Joy Division and is all over The Cars’ “Moving In Stereo”. It produces the lush Solina/String Ensemble sounds plus has a polyphonic synthesizer section with a voltage controlled filter, LFO, and ADSR.

Overall good condition for a 40 year old synthesizer, with some cosmetic issues as visible in the photos (scratches on the paint of the case, etc)

Synthchaser Precision LED slider upgrade. All 15 of the old original sliders have been replaced with new, smooth, high precision LED illuminated sliders. The difference in the way these sliders feel and perform compared to the originals is a huge improvement.
Synthchaser Capacitor Kit installed – 108 polarized capacitors in the synthesizer (not just the power supply) have been replaced to help provide stable operation for years to come.
Keyboard rebuild – New key bushings installed, keys removed and washed, key bed leveled, key contacts cleaned and adjusted
Oscilloscope Calibration – Fully calibrated to factory spec under measurement by oscilloscope

The 4075 filter has not been modified and has the original capacitors and frequency response. This can be enhanced upon request by the buyer. ” Click here to visit listing on eBay

used omni 1 ” Up for bid is a rare, good condition Arp Omni 1 from 1976. It will be a while before you find another one of these in this good, working condition. There are some scratches here and there, as is expected of a 40 year old instrument. And there is a strip of velcro adhered to the top of the case. I haven’t attempted to remove that. Otherwise, everything works to spec. The only thing “wrong” is the indicator light on the 16′ Wave button no longer lights up even though the button is still engaged. The button still works, it is only the light that doesn’t turn on. This Omni was recently gone through and had many things restored and updated by a professional technician. This is the list of repairs and updates…

– Make manufacturer-recommended power supply modifications
– Upgrade all 70’s tantalum and electrolytic capacitors with modern electrolytics
– Upgrade all early 4000-series CMOS chips with modern versions
– Clean button switches as much as possible (cannot rebuild and no longer manufactured)

Please Note- Some of these were deemed no longer functional, so the original mechanical button inside was replaced with a digital circuit. Everything still looks and works exactly the same, the only difference is there is a small aftermarket circuit board inside

– Remove/clean/rebuild/reinstall slide pots (no longer manufactured)
– Replace disintegrated keyboard bushings
– Recalibration
– Replace bass volume and main volume pots” Click here to visit listing on eBay

used omni“Up for auction is a rare, really good condition Arp Omni 1 from 1976. Really good condition. It will be a while before you find another one like this. The word of mouth story with this guy (none of this is confirmed to be true, its just what I was told) is that it was purchased new by a guy who owned a recording studio…supposedly this is one of the first studios that the Red Hot Chili Peppers recorded in and even more supposedly they played this on a couple recordings (again, this is not confirmed, just what I was told). So the studio ended up closing, and this was given to a friend of the studio owner, where it then spent the next 20+ years in an attic. I purchased it in completely non-functional condition, and then did a huge restoration. Everything now works to spec. The only thing “wrong” is the indicator light on the 16′ Wave button sometimes turns off even though the button is still engaged. The button still works, it is simply the light that intermittently decides to turn off. Here is a list of most of the repairs and updates…

There was a lot of time, work, research, and money put into restoring this cool piece of electronic music history, and this is now one of the better ones you will find. If I were actually a synth player, I’d be keeping this because its really cool. Definitely a conversation starter. Message me with any questions. Also, it comes with the hard case in pictures, but does not include the stand. Due to the fragility of the old electronics, I don’t want to let this get banged around in shipping, so I am offering this as a Local Pickup Only please. I am willing to deliver within reason.”

omni” Up for auction is a vintage ARP Omni synth that’s in need of a little more attention than I’m qualified to give to it. I acquired this ARP about 18 years ago after spending about two years of careful searching. The synth operated flawlessly up until about 2010 when a hanging note started to manifest itself the viola and/or violin settings with two or more keys depressed. Upon testing it prior to deciding to list it, the discordant note becomes present as soon as either the viola or violin settings are engaged but is not present while using the bass or cello settings. It is also not present when using it in straight synth mode on the lower keys or in any monophonic setting.

Anyhow, I’ve decided at this point that it would be better to allow someone else with the intent of bringing it back to 100% have it.. The opinion I received when I described its symptoms to an authorized ARP service professional that that a cap job was needed and that this would restore it to full functionality.The synth has always been well cared for in my possession and is in the exact same condition it was at the time that I purchased it from a reputable music store I believe.” Click here to visit listing on eBay

arp_omni ” Up for auction is a vintage ARP Omni synth that’s in need of a little more attention than I’m qualified to give to it. I acquired this ARP about 18 years ago after spending about two years of careful searching. Despite it missing a key at the time of purchase, the synth operated flawlessly up until about 2010 when a bad note started to manifest itself in the upper two thirds of keys using the viola and/or violin settings with two or more keys depressed in that register. Upon testing it prior to deciding to list it, the discordant note becomes present as soon as either the viola or violin settings are engaged but is not present while using the bass or cello settings. It is also not present when using it in straight synth mode or in any monophonic setting. I’m sure there are places in Arizona that are qualified to service this, but the two people I would have trusted this to and that I knew to have been authorized ARP service professionals both retired before I got around to taking it to them. I regret that as this is perhaps my favorite piece of equipment despite that I haven’t had an opportunity to use it in a creative capacity for approximately a decade at this point. Anyhow, I’ve decided at this point that it would be better to allow someone else to have it than to continue to allow it to sit unused in its present condition. The opinion I received on it when I described its symptoms to one of the individuals I would have taken it to was that a cap job was needed and that this would restore it to full functionality. It’s sliders and switches would also benefit from being cleaned with DeoxIt which is something I’d like to do but am not entirely comfortable with opening the Omni due to lack of familiarity with routine cleaning and servicing of synthesizers. The synth has always been well cared for in my possession and is in the exact same condition it was at the time that I purchased it from a reputable music store. Pictures 4, 5, and 6 highlight cosmetic defects and the one missing key. The screw that would hold on the key is still present and the function of the key is intact.” Click here to visit listing on eBay
