“Up for sale is an ARP PRO/DGX. Has been sitting in my studio unused for at least 12 years. Cosmetically it is in OK shape with visible dings and scratches but nothing big. The portamento slider is missing the end cap. Everything on it works, but it needs servicing. All the keys work, but some are finicky and needed several hits to wake back up. The keyboard feels really good with only one G# being overly clicky. All presets work. The Clarinet button took several presses to wake back up, but was mostly consistent afterward. The sliders, touch sensor effects, and portamento switch work. Volume and Brilliance are a little sputtery, but the instrument does produce a clean sound after wiggling them. Pressing down a key to engage the touch sensor effects works but is quite sputtery and inconsistent and is the part of the instrument most in need of service.” Click here to visit listing on eBay

“ARP PRO-DGX Monophonic Analog Lead Synthesizer in excellent condition.
Unit is in working order. Was recently serviced – had the bus bar cleaned and a general check-over by Robert Rosen of Rosen Sound in Burbank, CA. All of the functions work, including the AT controller under the keyboard.
The Pro Soloist was famously used by Tony Banks of Genesis. With a very unique architecture, this synth is difficult to recreate on other mono synths. If you’re going for that vintage Tony Banks sound, this is it. I used this unit 4 or 5 times on stage and it always delivered. Sad to see it go, but the time has come. Perhaps it will be yours.” Click here to visit listing on eBay

The Pro DGX is officially called the Pro Soloist/DGX (as shown on the back panel). This is a version 1 DGX; there were 2. It has the same filters and circuitry as the Pro Soloist, except the rocker switches are changed for push button switches. The switches are a bit slow if the Synth sits unused but they work fine. Sounds Amazing.” Click here to visit listing on eBay

“For sale is an excellent vintage ARP Pro/DGX Mk. I, aka the Pro Soloist III. This is the model to get! It has the same sounds and fat ladder filter as the Pro Soloist, but with more reliable and more performance friendly pushbutton voice selection switches. This keyboard is the sound of 1970’s Genesis.
This synthesizer has just been overhauled and serviced by Synthchaser, the west coast’s leading ARP specialist – recapped, new key bushings, new LED sliders, new aftertouch sensor, new mahogany wood side panels, fully functional, calibrated and sounding great. Comes with a brand new flight case to keep it safe during shipping and forever after.
Overall great condition for a nearly 40 year old synthesizer, with some small paint blemishes as visible in the photos.
Synthchaser Precision LED slider upgrade. All 4 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 – All reasonably accessible polarized capacitors in the synthesizer (not just the power supply) have been replaced to ensure stable operation for years to come.
New aftertouch sensor – The original aftertouch sensors are a common failure point and the aftertouch effects are what makes this synthesizer so expressive–we replaced the aftertouch sensor with a new long-lasting one to ensure the aftertouch will work for years to come.
Action restoration – New key bushings installed, keys removed and cleaned, buss bars cleaned and key contacts adjusted
Brand new flight case to keep it safe during shipping and forever after
New mahogany wood end panels
New bottom case panel
Aftertouch and all aftertouch effects working great: Volume, Wow, Growl, Brilliance, Volume, Vibrato
Oscilloscope Calibration – Fully calibrated to factory spec under measurement by oscilloscope”

Power supply just fixed,

2,Key contacts / buss bar and j wires tarnished, hasnt been cleaned in years. Will clean up nice, and come back like new. Good thing is the contacts and bar are not worn or crooked from novice cleaning, its nice and pristen. It the typically poor connectivity that ocurs when not using, or cleaned
3,Touch sensor needs replacing
Decided to save the $ on the repair tech and give the option for the buyer to clean, and keep the price lower

“We recently acquired the contents of a music store that has been closed for decades. We’re early in the process of separating the trash from the treasure and this is a treasure for sure!
This is an ARP PRO/DGX (Soloist/DGX) Model 2720. This synth has a low serial number of 2720 0385 and uses the more desirable 4034 filter. It’s in pretty good overall condition, but it does need some work. It was stored in a dusty warehouse so it could use a thorough cleaning. It is missing: two slider knobs (sliders still work), one of the tilt screw feet from the bottom, some of the screws inside that hold the wooden sides on, and the sheet music rest back. We cleaned the key contacts and all of the notes sound. When I first powered it up all of the touch sensor features worked, but now I can only get the pitch and volume to work consistently. Some keys seem to trigger the aftertouch easier than others. I’m only capable of doing very rudimentary repairs, so I can’t troubleshoot the cause. Portamento works great. Repeat works, but doesn’t seem to work on all of the voices. Octave Transpose works, but the switch should be cleaned. The other issue that I noticed is, when you first power it on, all of the voices can be selected, but, after playing around with it for a little while, the first half of the voice buttons select sounds from the second half. (Meaning the “Bassoon” button will select “French Horn” instead)” Click here to visit listing on eBay
“Hello! Thanks for checking out my link, this is a arp dgx pro. Very rare keyboard. It’s 100% analog and from late 1970s. This keyboard works, everything on it works it just is in old condition. It’s missing screws on the top front by the keyboard, which isn’t a problem unless you flip it upside down, it opens up on a long hinge on the back. It’s take like 3-5 small stews to just screw in not a problem. One to two keys is a little flimsy, what I mean is, you sometimes gotta push down harder and wiggle it, but sometimes you don’t. There are four sliders on the right, two are missing the original knobs, but you can still use them, the octave slider has broken off but but you can still switch it with like a tool. All sounds work but sometimes you gotta push down harder or hit it like 6 time and it goes. All touch features work, and the output also work. ”
