“Model number 2321
Serial number 23210981
UK mains powered 240 volts
It has a few scuffs & marks, & the facia & wood sides have faded (see photos).
Please note that I have 2 of these for sale with close serial numbers (see my other listings).
The main difference between the two is that the other one has an additional switch & control knob on the left-hand side, but this one has not (see photos).
The synth was the property of my late brother & I am selling it as part of his estate.
Unfortunately, I have little knowledge of this sort of equipment & I have only been able to carry out some basic checks as follows:
When plugged into an active speaker & powered up it makes an oscillating noise, which can be varied using each of the sliders.
It also responds to each individual key on the keyboard.”

“ARP AXXE Odyssey Vintage Analog Synthesizer Model 2313!!NEEDS WORK. Condition is For parts or restoration project. It Powers On it has 4 sliders broken it’s missing 1 knob and back plate. Some keys are bowed up. But is in very good condition considering it’s age.”
“Vintage monophonic synthesizer. Turns on and got sound out of it; not an expert but it could use some servicing. Due to its vintage nature, this synthesizer is being sold AS IS. NO returns. Prefer local pickup.” 
“Bought this to play with but don’t have time. Unit powers up but no sound is generated. Intact except for one adjustment knob missing. Comes with one factory settings manual and a copy of owners manual. Does not make any sounds so bid accordingly.” 
“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 ”

“This has been used on the road and has a few scrapes, scratches, and battle wounds.
“I purchased this vintage analog synth with the hopes of finding time to get it going again… alas no time for such fun so its time to move this wonderful sounding synth to someone who will love it. The face membrane has a crack in it which I believe is cosmetic ( see photos for details of scratches etc etc). The main issue is it powers up but makes no sound. There is a great tech in Boston that was the right hand man for A.R.P. himself who should be able to help anyone who buys this to get it going. I was always an ARP guy and loved the sounds of this.”

“Very good visible condition for its age. Very good working condition, **NOTE** the MIDI does not track the MIDI notes right, other than this, it receives notes, but it won’t play the right pitch.” 
“ITEM USED
“Original Arp Axe. Sonically Amazing and functionality, all working perfectly. Runs from 240V 3prong Aus power plug. On/Off light stays off now. Cosmetically there is a wood chipped on the top left panel, it seems that only the timber itself was damaged, and 2 slider coloured plastic covers are missing-pulse width mod and vcd freq. Always has been looked after and in great shape, although I bought a copy of the 12 page service manual online, it has cool info like calibration points, comes with it. Pickup, Packed well and shipped worldwide.”

“Analoger Klassiker!
“Good condition for its age. No issues and serviced before I put it in storage. As you can see in the last picture the panel on the underside is missing but it does not affect performance in any way.”
“ODYSSEY is 2 VCO, but its 1 VCO version, a synthesizer that can be said as a low-priced version.
“Up for sale is this ARP Axxe.
