For sale is a rare vintage Arp Quadra synthesizer keyboard that just got back from a full servicing by Synthchaser. Work included a complete re-cap, new slider pots (which can be led activated at a later stage if desired), new touch panel membrane and keybed refurb. It's fully functional and good to go. We have a long demo video made by Synthchaser we can share on request.The only issue worth mentioning is the lower transpose button is not working, but the upper transpose button does work and performs the same action. We have sold Arp Quadra's in the past for $12k - $15k and it's been a couple years since we last listed one for sale. These are very cool vintage analog synths.
