Classic String Synthesizer





The ARP Omni is one of the warmest sounding and most sought after of polyphonic analog synth / string machines. It sounds similar to the popular String Ensemble Solina IV but offers more features as it has not only a string synth but a separate bass and synthesizer section too! The synth section is a tweakable analog synth which sounds really cool. Nothing sounds like an Omni to me, thanks to its unique phasing effect and single envelope trigger option. This was a very popular keyboard in the 70s and used by too many musicians to list. If you like synthetic string sounds or want to recreate that 70s retro vibe, the Omni is for you!


Our items are as described, which means no typical surprise post-sale repair bills or serious flaws typical of most vintage gear deals! 

This ARP Omni is in excellent shape and has been fully overhauled by professionals.  There are a few minor scratches but overall cosmetics are excellent - check out the photos and you'll see how clean this unit is!

This Omni should be worth a lot more than most Omnis out there.  ARP Omnis have lots of tantalum capacitors inside. These relatively expensive electronic components go bad over time and need to be replaced. They are often the reason for Omni problems, which are VERY VERY common. We've seen many Omnis and know this for a fact - unless they've had their caps replaced, it's likely they have problems or will develop them soon. Most Omnis we've seen which were advertised as working needed repair. Anyway, to fix capacitor related problems, you can take the cheaper route and replace defective capacitors one at a time or you can invest a good amount of time and money replacing ALL these tantalum capacitors which will inevitably fail one at a time. In this case, we went through this Omni and replaced ALL the tantalum capacitors with new ones. Why? Because we want this Omni to work great for you! A full capacitor replacement will usually cost you several hundred dollars. It requires a decent investment for the parts and a lot of time and money in tech fees.  Every time we overhaul an Omni we say "never again!", so this may be the last 1 we do... 

This Omni also includes the Tim Smith (RIP) filter modification which increases the maximum filter cutoff frequency so that it sounds way better than the stock Omni filter.  We also went through this machine and replaced all other capacitors, not because it was needed, but because, again, we want to do what we can to make this Omni to perform reliably for whoever ends up with it.  Oh yeah, it works exactly as it should. 

This Omni plays great and sounds great and is better than the rest of the ones on the market.  We'll be sad to see it go!
