“ARP Avatar Guitar Synthesizer 2223 Made In USA.
“This is for sale an Arp 3604-P keyboard controller and and a 2600 Arp service manual.
“Recently serviced. Excellent working condition. Comes with original guitar pickup and cable!” 
“Very good condition, with some wear as expected for its age but overall still nice shape. Most of the wear is on the outside tolex, the front panel face and keyboard itself are in great shape. Includes both lids to unit and keyboard along with keyboard connecting cable. Recently fully serviced by professional tech. We’ve had many 2600s pass through our shop over the years and we found this particular unit to sound fantastic. It’s 100% fully functional, except for 2 small issues worth mentioning: one slider shaft has a broken tip (in Voltage Processor section, probably the least used part of the synth and you still have 2 other working Voltage Processors), and the keyboard input jack to VCO3 is hardwired to receive voltage from the keyboard (jack will not bypass the keyboard input). Other than these two issues the unit is working as it should. At some point this was modified to accept standard 3-prong cable instead of the unusual oval shaped cable they original came with. ”
“I don’t need to tell you keyboard wizards how rare this is or its musical pedigree! There are none to be had now and I am reluctantly parting with her due to a downsize house move. I have owned this synth from New and imported it around 1974. Unfortunately I don’t have the original box though! This keyboard is in very good condition with all original knobs and sliders and there are no scratches or damage. Please note I am aware of one minor fault where the sustain mode is on all the time but I am told this is not a major problem? I am not being greedy but I am not giving her away either! I just want it to go to an enthusiast who will continue to care for her. I would prefer buyer collect for obvious reasons but am prepared to courier it if needed (UK around £50 delivered I think).”
“ARP Pro Soloist 2701 classic synthesizer vintage with Anvil road case. Very good condition.” 
“So I bought this about 6 months ago and am not using it. It’s working pretty well for a synth from the late 1970’s. As you can see from the invoice picture it was gone over and updated quite a bit by Synthchaser in California. This was before I purchased it. there are still a few issues I’ve noticed. There is sometimes a light click when keys are depressed coming through the amp. The string section seems just a little noisy, but this could be the era in which it was made? Not sure. Also the string section will occasionally cut out, but I’ve tracked this down to a wiring harness which I will mark. Not sure if it’s a wire or the plug. So it needs a little attention and it does have some cosmetic rust and wear, but overall it’s a pretty cool vintage board. I just don’t have the time for it. ” 
“This listing is for a Vintage ARP Odyssey II 2810 Electronic Music Synthesizer. I acquired this as well as some other items from a man that was an avid collector in vintage electronics his whole life. He stated that he only set it up no more than 3 or 4 times since he purchased it new in the mid to late 1970’s. It has been sitting in a climate controlled closet in the original box all these years which is why its in excellent condition cosmetically and is extremely clean as well. It comes complete with the original foot pedal, an additional larger foot pedal and the instruction guide. Both pedal cords are still in excellent condition as well. You will also receive a 211 page book titled “Learning Music with Synthesizers”, as well as a hard to find complete set of full size, two-color patch charts that are designed to fit over the control panel of the instrument, providing you with the proper control setting for sixteen popular patches (see last pic). It is extremely rare to find these patch charts let alone a complete set still in excellent condition.” 
“Condition: Good Overall Condition. Works well per owner. Module has some scuffs/marks. Left wood side panel is chipped on the corner. See photos for more details.” 
“Refurbished 12 months ago including retolexed case. Good working order has been used very little since the service. Superb sounding and increasingly rare instrument. Excellent sounding reverb and ring modulator. As used by Todd Terje, hot chip, etc etc etc etc ” 
“This vintage ARP is being sold for parts/repair. It does power on (you’ll need a Belkin 17952 power cable available for $20 on eBay) but is being sold as is untested and intended to be sold to someone who would like a great opportunity to buy one of these at a cheaper price for restoration or re-sale purposes. ARP itself is in nice condition shape just missing a few faders the keyboard is in rougher condition and may need more work than the ARP itself.” 
“Fully working, original Mk2. Lots of regular use in studio, although less use over last 10 years.”

“Recently (a couple weeks ago) refurbished by one of the best techs in SoCal. Most 1970s Odysseys are in terrible electronic condition even if they look good. This one looks good and is in excellent electronic condition. ”

” Classic vintage Arp 2600 analog semi-modular synthesizer with model 3620 keyboard in absolute museum quality condition. This synth was in climate controlled storage, and unused for over 25 years of its life. It has just had a complete refurbishing and had it’s op amps upgraded by RetroLinear, and is absolutely 100% guaranteed to be in perfect operational condition. As you can see from the pictures, this synth is in immaculate cosmetic condition, with only the most minor of rub marks on the case. It’s never been on tour, or used for any live performance. It even smells new! You won’t find a cleaner or more perfectly functioning 2600 anywhere.

“Vintage ARP OMNI-2 Analog Keyboard Synthesizer
” Perfect working order & recently serviced by an electronics engineer. ”
“The ARP Axxe is a completely variable synthesizer, ideal for live performance operation. The Axxe provides many of the features of more expensive synthesizers and can serve as the nucleus of a larger synthesizer system by interfacing with other ARP instruments.
“For sale is a vintage ARP Axxe Synthesizer (Model 2323) synthesizer that is in superb physical and is 100% functional. It comes with a special built plywood case. The Axxe is a vintage, American-made monosynth with a rich, fat analog tone. This synth is not a cheap Japanese (but made in China) clone. It is the real deal. Not only does this synth look great, sound great, and play as if it was only a couple of years old, it is collector’s item from the golden age of analog synthesis. Unlike the recent Odyssey clone by Korg, the electronic circuits in this synth have not been redesigned and the circuit boards aren’t stuffed with cheap, Chinese substitute components ”
” For sale is my Arp Solus. It’s in great shape for its age, there is some wear so be sure to check out the pics to make sure you like it. Overall it’s quite nice, especially the front fast. Includes out case lid (one latch is broken but the other latch still holds it closed). The synth itself is excellent and fully functional, including some new sliders installed so they move real smooth. The other older sliders still move well. A few of the sliders are missing their caps but they are easy enough to move and I believe you can find some replacement caps online. Awesome rare analog synth, don’t miss out!”
