ARP Axxe

“Up for auction is an ARP Axxe monophonic synthesizer from the 1970’s. Model number is 2313 and the serial number is 1156. This has been in storage for many years and is in need of a deep cleaning and rebuild for proper operation. No broken keys or sliders but it is missing many of the slider caps. It features solid walnut end caps and comes with the original Owner’s Manual and custom Anvil road case. The road case foam has deteriorated in storage and will need to be replaced. It does power on and you can get sound out of it. The sliders are stiff and need to be rebuilt or replaced.

This Axxe was modified at the ARP factory (I drove it there personally!) to add a Portamento switch, VCF over-tracking and an XLR output.

I bought this new in the late ‘70s and had a lot of fun with it then. I don’t have the time or the capacity to give it the attention that it needs. Look at the pictures and ask any questions. Selling as-is since it is not operating as it should.”

“ARP Axxe Analog Synthesizer.

In great condition – museum quality! All original.

Classic analog synth. Sounds amazing! Great for fat analog bass and soaring lead sounds! Can also make some pretty quirky sound

effects with it like ‘Heavy Wind’ & ‘Seagull Chorus’. Very easy to program and lots of fun to use.

Sad to see it go but need to down size my studio 🙁

Was last serviced in 2020 by Kent Spong.

Also comes with the original patch book.” Click here to visit listing on eBay

“A very lovely ARP Axxe in fantastic cosmetic condition!

**No output from the VCO, on either of the waveforms**

The Noise output can be heard, as can the filter, which self-oscillates mightily with the resonance up, these little things are beastly!

You can process external sounds through the filter, and modulate that from the LFO.

Doesn’t seem to be triggering from the keyboard (I used the slider directly, as well as a Keystep via CV/ Gate) and not sure the ADSR is working correctly either, the Release seems to act as VCA gain level, rather than fading out accordingly. The last time I looked at this, I recall it was 100% aside from the lack of signal from the VCO, so may be missing something. The Key Repeat slider seems ok too.

A pretty simple circuit, schematics and parts easily available, doesn’t look to have been messed with in any way. It is possible to plug the connector cables in backwards on this ARP gear, but pretty sure it’s all in the right place. If the sliders flake out, they can also cut the audio, but not really suspecting those either. Straightforward, if time-consuming to dismantle and clean those if needed, and I actually have a few spares if it does turn out to be a dodgy fader.

100% original, some missing screws in some of the pics to show the innards, but they’re all included. May *possibly* have some caps knocking around too.. they’re notoriously brittle with age and often split into pieces, and the sliders look and function just fine without them.

*have found most of the sliders, see last pic, including one broken, glued & broken again.. should really clamp these while gluing if poss*” Click here to visit listing on eBay

“looks nice in general but there are some flaws: the side wood panel has a crack, and the bottom is missing all but two feet ( i have seen this many times before; previous owner opens up a can of worms and looses the screws…dummy)
powers on
lights up
the sound is working but notes drift and it seems to have a mind of it’s own…doesn’t work right

SOLD AS IS: looks good with flaws noted, needs service to operate perfectly” Click here to visit listing on eBay

“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

“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

“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

“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

“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

“For sale is a rare vintage Arp Axxe MkII. This came from the original owner and was well taken care of, while it shows some wear on the sides the top, front rear and bottom are quite clean. Top graphics are bright with very minor wear.
Functionally it has not been serviced over the years so it will need a regular checkup. The sliders are a bit stiff/gummy/scratchy as typical on old Arps, and the switches are a bit stiff/scratchy, the keys don’t trigger perfectly and are clacky/not fully level. It appears that the functions are working for the most part and sounds as it should, but considering we have not had time to service this it will be sold as-is needing some maintenance. We’ve priced it lower accordingly.” Click here to search for synths on eBay
