“Arp Quadra Vintage Analogue Synthesizer plus New BSH Custom Flight Case.
I’ve owned the Quadra since 2012. I used it a lot with PETER HOOK AND THE LIGHT to recreate synth sounds of early New Order songs, for our LIVE shows.
It was fully overhauled by Andy Jury at Synth Prof late last year 2019.
The Overhaul included a full repair and service, plus a mod to the filter which corrected a design flaw with resonance range and also an external clock input for the arpeggiator.
I will include the full detailed service notes with the sale.
Fantastic oddball of a synth with lots of great features, including the phaser, which you can route any instrument thru, using the Quad outputs with an insert cable.
I’d love to keep the Quadra but it rarely gets used these days and deserves to be used to its full potential.
It had a slight ding to the left side, right next to the Kyb Trigger switch, it has just bent the metal slightly, only cosmetic. Not bad condition for its age, some scratches here and there to the paintwork, mainly underneath where it’s been sat on numerous keyboard stands throughout its life.
Thanks to the complete overhaul last year, it is now in perfect working condition and ready to go.”

“Due to a non paying bidder, this item is being relisted.
This ARP Quadra was serviced a few years ago by MIKE Metz at Thesis Audio Service in Kansas. After I got it back from him, it was fully functional and beautiful.
It is still beautiful, just not fully functional anymore. I know that the sliders are all intact, the membrane switches all work, could only need just a little bit of money to get it running.
Since Mike worked on this last, I would recommend sending it to him for service.
This Quadra has a unique modification. The switch on the left side, which was professionally installed, allows you to take the chorus effect out of the mono signal which is pretty cool. An extra feature added that you do not see on any Quadras that I have seen.
I was told this Quadra was once owned by John Elefante of Kansas before he joined Kansas. I believe Mike even told me that he worked on this synth while he toured with Kansas at one point back in the day.
This unit comes with an anvil case for safe shipping, and a spare custom programmed CPU.” Click here to visit listing on eBay

“For sale is a vintage and rare ARP QUADRA. Cosmetically it’s in very good shape. SEE PHOTOS I think it looks absolutely amazing. The graphics are crisp and very little signs of use all around. There are some areas where the black paint is missing/scratched off along the top back edge where the hinge is. The sides have signs of wear along the edges but are mostly along the back edge. PLEASE SEE PHOTOS FOR CONDITION AND PAINT ISSUES. Functionally there are no known issues with the unit, however I am not an expert. The unit powers on, all keys trigger properly, only the sliders in the Phase Shifter / Output Mixer section have been replaced and do not have the knobs/tops on them. All other sliders and panel switches also appear to work properly. The two sliders in the Porta-Mento section are missing knobs/tops. All the touch switches and LEDS function properly. I have played it out the MONO OUT 1/4″ jack sound output however I have not played it out the other outputs. + owner’s manual”

“Circumstances force the sale of my beloved Arp Quadra Synthesizer. If you are looking at this auction I probably dont need to go into detail about what a legendary piece of gear this is. I powered the unit on briefly but was unable to get any sound. Great overall condition but does have a few snapped sliders as seen in pics. I am selling as a parts machine. It does appear to be complete to me but I dont have a schematic to compare it to. ” Click here to visit listing on eBay
” For sale is an Arp Quadra, one of the rare vintage analog synthesizers. It’s a super cool synth with very unique tone and layout. You hardly ever see these up for sale and if you’re reading this auction, you’ve probably been already been waiting a good number of years one of these. This particular unit has some issues and is sold as-is for parts/repairs. Please read below for a full description and additional pictures.
Cosmetically it’s in near mint shape. Looks absolutely amazing. The graphics are crisp and very little signs of use all around.
Functional it has some issues but it should be fixable in the right hands.
After extensive testing, here’s what’s working:
Powers on, all keys trigger properly, sound outputs from the main 1/4″ outs on the rear.
Moving from left to right on the panel:
Bass section: All sliders work, Elec Bass 16′ and 8′ work. The Strings bass 8′ works but only on occasion, and the 16′ does not seem to activate.
Strings section: all parts working
Hollow waveform: not responding when pressed
Poly synthesizer: 4′ is working, other parts of this section temperamental and not fully working
Phase Shifter/Output mixer: All sections appear to be working as they should
Lead Synthesizer: All sections appear to be working as they should
Programmable Voices: All buttons 1-16 respond with changing LEDs and changing sounds, though some patches do not sound as exciting as others, likely due to corresponding sections not being fully functional.
In general it could use a tuning/calibration and some sliders show scratchiness and are a little on the stiff side, but still easy enough to move. Any features not mentioned above have not be tested.
Considering there are some functional issues, this unit has to be sold as-is condition, for parts/repairs with no guarantees on its functional condition. It can be shipped with the included flight case or packed without the case into a very safe cardboard box with many layers of bubblewrap (which I personally recommend from experience as it cuts the weight down and keeps the synth extra protected). In any case I’ll do my best to pack it safely for the trip.” Click here to visit listing on eBay
“I have 2 of these amazing beasts. This one is intact, has one slider stem broken, (bass decay)
It needs full calibration. All the membranes are functioning. When lifting the top to service the bass 4ft and the hollow wave goes blank. Every other membrane is 100 percent” Click here to visit listing on eBay
“Condition:This synthesizer is in good cosmetic condition. All sliders are present and unbroken with the exception of the sustain slider on the envelope generator, which is present and workable, but broken off slightly higher than the panel. The audio mixer slide has wear on paint surrounding it. There is board tape residue on the panel above the keyboard and more residue on the chassis below the keyboard. The unit works, but has issues” Click here to visit listing on eBay
Super rare and hard to find working!
I purchased this broken and restored it.
I spent countless hours bringing this back to life.. Pretty much every element to this synth was non working when I got it.
-All sections working
-All outputs working
-All membrane buttons work perfectly except the left “interval” button. This did not bother me as the right “interval” button works perfectly. ( there is no difference between the L&R interval)
The two things worth noting are that at some point in its life, the Quadra took a blow to the back left corner. You can see in the pics where the paint has lifted here.
(The paint could easily be touched up)
I’m only selling because I already have a Quadra. (that I also restored)” Click here to visit listing on eBay
