Axxe

“This Arp Axxe is sold as is. It does power up and makes sounds but I do not know enough about it to know if it is working correctly. So I am selling it as “not working/parts” but I am sure someone that knows about these will be able to get it working correctly. It has been in storage for a number of years and the foam inside the case was deteriorated and covered the keyboard so it will need to be completely cleaned. The unit has a few scratches and scuffs and one piece of the wood cabinet is broken and missing (see picture with arrows). The anvil case is heavy duty, all of the foam inside has deteriorated as I mentioned earlier and has been removed so you will want to add some new padding. The paper sound cards have some wrinkles and some are torn and have stains. The owners manual is in good condition.” Click here to visit listing on eBay

“I believe this is a Mark II with the pressure bender, not the rotary knob?

In good working order, keybed restored, video link included.

All key bushings replaced by new set.

The sliders could use some cleaning as there is some noise when they are moved as you hold down a key.

“For your consideration is an ARP Axxe Mk II vintage synthesizer in fantastic functional and cosmetic condition. The instrument was taken apart, cleaned thoroughly, checked for correct operation, and any necessary repairs were made. All switches and sliders were cleaned and lubricated and perform smoothly. The keys were removed, washed and polished and the bus bars and contact wires cleaned and adjusted. The key bushings were replaced recently and are in good condition. As a result the action plays responsively without squeals. The PPC pads work as expected. Notably, a full set of slider caps is present, which is almost never seen on similar units for sale. A full oscilloscope calibration was done and the instrument plays in perfect tune.

Despite being a single oscillator and envelope synth, the Axxe is capable of producing surprisingly strong sounds. The gamut of delicate to aggressive ARP fare is on tap. Mixing the sawtooth and square oscillator waves together results in a quite full sound that stays completely in tune throughout the playing range without the wave cancellations or unintended detuning that two oscillators might create. A way to add motion to this sound is to modulate the pulse width of the square wave with the LFO or envelope (or both). Depending on the speed of the LFO, an effect much like two oscillators beating against each other can be had. This instrument is superb in the bass area, and really sings in the high range.

An IEC power cable will be included. The original slightly damaged wood sides were removed and a pair of new cut-to-match maple replacement sides will be included as well. These are bare and left for the buyer to finish however they see fit. A test board showing stain color possibilities is in one of the pictures. The boards can be attached to the chassis with two-part epoxy available at any home improvement store, and held in place with clamps or even some heavy books until they set.” Click here to visit listing on eBay

“ARP Axxe Vintage Synthesizer.

Great physical condition, just some small marks on the wooden ends and in great working order. I’m just not using it as much as I should and need to clear some space

Capable of some really nice sounds and comes with the original manual.

The keyboard was re-bushed by the previous owner. He also changed the IEC socket and switch.

I’ll be sorry to see it go.” Click here to visit listing on eBay

“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

“This item is in poor condition and works for the most part. Faders are in rough shape. Also, the filter section and sample/hold section are not working” 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

“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.

“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
