ARP Odyssey

“ARP Odyssey MkIII (vintage) in OK condition: some scuffs at the edges (see pics) but the face plate is very nice. Recently serviced:

– All faders opened and cleaned, re-lubricated. Feels and work very well.

– New keyboard bushings.

– New parts in the PSU.

– Sub-Osc mod, the “VCA Gain” fader now controls the volume of a sub-oscillator (copied from a SH101).

– AR fast/slow mod to make the AR-envelope faster.

– Free run mod: choose if the LFO shall re-trigger on every new note or if it should run free.

– Timothy Smith Filter mod, which makes the filter open up more

All mods are non destructive and easily reversible. The switches on the back are fitted in the jack holes with the jacks still present inside. ” Click here to visit listing on eBay

ARP Quartet

“ARP Quartet Brass / Strings / Organ / Piano Analog Synthesizer PARTS READ DESC. Condition is “For parts or not working”. NOT fully tested. This is being sold FOR PARTS.

The end of the power cable where it plugs into the machine appears to be broken and has exposed wires. Due to these errors this is sold AS-IS NO RETURNS.” Click here to visit listing on eBay

ARP Odyssey

“Arp Odyssey Mk1 2800 Synthesizer ( Full Overhaul And Calibration ). Condition is “Seller refurbished”.

Very Rare and Unique Original 1970’s Arp Odyssey Model 2800.

1970’s Original Arp Odyssey 2800 Mk1

Refurbished /Serviced /Calibrated

Pretty much a full Overhaul!

I literally just picked this beast up from my tech today 3/8/2021

As most of you know, the 2800 Mk1 is essentially a white face on the outside.

Somewhere in-between the Mk1 design and the Odyssey II / Mk2/ Rev 2 launch,.. there were a few transitional designs that ARP released.

They had the Mk1 guts along with the black and gold body. Odd, but a Pretty Obvious piece of synth history here.” Click here to visit listing on eBay

ARP 1621 Sequencer

“Sequencer is in “good” condition for it years.

As seen in the pictures is a VERY LOW Serial Number 86.

This unit belonged to Patrick Moraz of the bands “YES” and “The Moody Blues”
It was given to me during the time I worked with him 25ish years ago.
He is also pictured on the original Manual Art.

Has a as far as I know one of a kind “Twin Gate BUS MOD”. See picture with original sticker of work done in England,

I don’t fully remember what the Twin Gate BUS MOD did, but I believe it allowed for 1/32 notes.
I cannot find any documentation to prove it though.

I have no way to “FULLY” test the device anymore.
It powers on and I can step through the sequence.” Click here to visit listing on eBay

ARP Axxe

“This beautiful instrument is in excellent condition, especially when considering it is almost 50 years old! Hard to believe. It was recently refurbished and serviced and everything works as it should. The only slight blemishes are cosmetic. Some of the printing on the top panel is faded, which is an easy fix. Also, I took off the removable slider caps to use for another ARP synth, and just haven’t had the chance to replace them yet. This doesn’t affect the sliders at all whatsoever. They are purely cosmetic and extremely cheap to replace. If this is an issue, I can replace the slider caps before sending out the instrument.” Click here to visit listing on eBay

ARP Axxe

“Up for grabs is an ARP Axxe Model 2313 with an extremely early serial number, made in Newton, Mass USA in 1975. This is the first iteration of the iconic mono synth, featuring the legendary “stolen” self oscillating Moog Filter. The later two Axxe Models do not have this feature. The filter is THE crucial aspect of a mono synth, and with a self oscillating one….sinusoidal bass and kicks will shatter your window panes.

The instrument was recently refurbished and serviced. Everything works as it should. It’s always hard finding vintage synths that work, and at this point…..this thing is an antique, although that does not stop it from being a useful instrument in anyone’s rig.” Click here to visit listing on eBay

ARP Axxe

“Powers on and makes some sound. Noise generator makes sounds. Low frequency oscillator seems to be working. A slider is broken off, and a few keys stick up or down (see pics.) Sold as is, no returns.

ARP Axxe

“1970’s ARP AXXE SYNTHESIZER Model 2313. Condition is “Used”.

The condition is “Good to Very Good” for the age. See Pictures.

I have owned this keyboard for over 30 years. I recently plugged it in to make sure I can get sound from it.

The keys on the keyboard work and the synth makes sound. It is FULLY Analog.” Click here to visit listing on eBay

ARP Axxe

“Vintage ARP Axxe Mk II synthesizer with new sliders. In tune and working!

The one oscillator’s saw and pulse outputs can be mixed with the white noise source. The oscillator may be modulated by LFO (square and/or sine), random sample & hold, and ADSR. Pulse width adjustable from 5% to 50% and may be modulated by LFO and ADSR. 4 pole voltage controlled filter with self-oscillating capabilities. Filter may be modulated by keyboard control voltage, random sample & hold, LFO and ADSR. Normal keyboard triggering mode, as well as keyboard repeat and auto repeat. Pitch bend control, portamento/glide, and transposable up and down 2 octaves. 37 note keyboard.

The case has some holes that have been plugged from a previous MIDI mod which has been removed. The trigger in/out jacks are taped off inside the case (the holes they normally mount in were enlarged by the previous owner). Sliders were replaced and oscillator tuned to get everything working, but otherwise the synth wasn’t serviced or restored in order to keep the price affordable. The keys all work, but the bushings are old and the contacts are dirty, so sometimes a key may double trigger. Some wear and marks on the panel, as shown.” Click here to visit listing on eBay

ARP Axxe

“1970’s ARP AXXE SYNTHESIZER Model 2310. It does power on and make sounds but due to the fact that I don’t know to operate it, I cannot confirm that every function works as it should. For that reason I’m listing it as parts or non working Unit powers on and makes sounds. I’m not sure how to operate it. It’s missing 3 of the rubber tips of the sliders but all sliders move and none are broken off. It shows expected wear from age and use and the bottom is missing some of the screws. It would benefit from a good servicing that I will leave up to the new owner. Things to know before you buy: it’s over 40 years old and is not a new item. Though I moved every knob and slide I don’t know how to operate it so I can’t be sure of what it will or will not do. I will not accept a return on this item.” Click here to search for synths on eBay

ARP Odyssey

“This vintage ARP Odyssey has just been fully serviced by Synthchaser, the west coast’s leading ARP specialist – recapped, new ICs, new key bushings, all new LED sliders, all new slide switches, fully functional, tuned and calibrated, and sounding awesome! The Odyssey was ARP’s answer to the Minimoog, a feature packed scaled down version of the legendary ARP 2600. This late model ARP Odyssey is equipped with the 4075 filter, a tasty 4 pole LPF found in all late model ARP synths.

The synth is in great condition, and was acquired from the original owner who bought it in 1980 and put it away in 1981. It comes with a wooden road case, and the foam is still good! There are touches of rust along the edges of the synthesizer (see photos), but they are not distracting from the overall awesomeness of this synth. This synth comes with Orange illuminated LED sliders to complement the Orange & Black color scheme of this late model ARP. I am willing to disable the illumination for the buyer before shipping, upon request. ” Click here to search for synths on eBay

Lot of ARP Omni PCBs

“ARP Omni 2480 Power Supply, Phaser Board, Synthesizer (including Low Pass Filter) Board. These were removed from a damaged ARP Omni approximately 10 years ago with the intent of building a standalone phaser and low pass filter and I never got around to it. The power supply worked when removed, and the low pass filter section also worked, though the sliders are stiff and need replacement. I didn’t test the phaser board before removal, so I don’t know if it works or not. Note there has been some repair work on the synth board (upper left, “Z3″) and the phaser board (upper right of PCB, solder side).

ARP String Ensemble

“ARP STRING ENSEMBLE SOLINA SYNTHESIZER VINTAGE. Condition is “Used”.
Its incredible to think of the thousands of songs that these things were used on-everything from Parliament Funkadelic to Gary Numan and still to this day-you wont find a Dr.Dre album without a Arp Solina on it.
This one still plays good for as old as she is(never gigged-just moved from studio session to session).Some of the wood veneer is cracking off but no real damage.” Click here to search for synths on eBay

ARP Pro/DGX

“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 search for synths on eBay

ARP Omni Project Machine

“For sale is my ARP Omni string synthesizer. This synth is not working – only the power on switch illuminates when it is switched. I’m not sure exactly what is wrong with it but these divide-down string synthesizers generally need to be rebuilt by a synth tech to become fully functional again. Physically it is in OK shape but will need to be cleaned up.” Click here to search for synths on eBay
