ARP Pro Soloist

“This iconic analog synthesizer with its fat ladder filter and expressive assignable aftertouch effects is the sound of 1970’s Genesis. This synthesizer is in pristine condition, includes a vintage tolexed case, and has just been lovingly restored by Synthchaser, the expert on these instruments.

I (Synth Chaser) have extensive experience repairing these instruments and have seen more than my fair share of Pro Soloists. This is hands down the nicest Pro Soloist I’ve come across to date. It is in excellent condition inside and out, and I’ve given the electronics a thorough and detailed restoration to make this a worthy addition to the most elite collections of vintage analog synthesizers. Restoration work included:

* New sliders

* All original slider caps present! A rarity in itself!

* New aftertouch sensor – The original aftertouch sensors are a common failure point and the aftertouch effects are what makes this synthesizer so expressive–I replaced the aftertouch sensor with a new long-lasting one to ensure the aftertouch will work for years to come.

* Power supply recapped

* All reasonably accessible tantalum capacitors replaced

* New power cord

* New key bushings

* Keybed leveled, bus bars and key contacts cleaned and adjusted, keys ultrasonically cleaned

* All voices working and sound correct!

* All touch sensor effects working!

* 1/4” Phone Jack output made “high”. These synthesizers originally came with a RCA jack as the high output and a 1/4″ jack as the low output. As most of my customers do not use RCA cables and prefer the high output, I’ve made the 1/4″ jack output high as well which is a common modification requested by my customers. This modification can be undone by cutting 1 wire.” Click here to visit listing on eBay

ARP Pro Soloist

“Rare find for me
1970s ARP Synth.
Stored for many years
it is in good condition
and comes with original music holder
but screws to hold it down are missing.
I am no expert in this
so please here me out.
The keyboard does power up
and after a warm up time
does play.
However, when switching on the effects
some work only slightly, partly
or not at all.
It is in need of
complete cleaning of all controls,
refurbishing and or repairs.
There is lots of info
on these on Youtube.
Videos about repairing them also.
Wonderful piece of 1970s music history,
sold as-is.
Thanks” Click here to visit listing on eBay

ARP Pro Soloist

” Vintage early 1970’s ARP Pro Soloist mono analog synthesizer in good condition. Made in the USA.

Classic synth made famous by Genesis, Steely Dan and many others during it’s day.

Comes from the original owner, an old time accordion player, who used this onstage as a one-man band.

Missing one slider tip. Owner placed glitter colored cloth over back panel. Powers up – all keys work and produces killer tone. Have not tested all of the functions.” Click here to visit listing on eBay

“This keyboard is in great condition especially cosmetically, it almost looks new. All sounds and functions work on it including the “touch sensor effects” however the keys and the sliders are very stiff and one slider is missing a cap. The stiffness is bad enough that it will need to be addressed so the price reflects this. Also when adjusting the volume sometimes the sound will go out but will come back once the slider is adjusted to the “right” spots. I had posted this earlier stating that it didn’t work in other ways but it turns out it works great I just had my headphones plugged into the wrong output. (Different outputs than I am used to, this thing is old school!)” Click here to visit listing on eBay

” I purchased this recently it had been stored for a while. I play guitar and tried this out through one of my old amps. It sounds amazing. All the voice settings work. Two of the keys are not as strong as the others on most settings. The sliders feel gunky, but work. At least two of the aftertouch settings need attention. The Wow and Growl seem to not work. The repeat works, the vibrato seems to work, the pitch shift seems to work the others might be in and out. I understand that these instruments should be gone through and I am starting this auction out what I have found broken ones go for. This one is not broken and with the right maintenance by a professional synth tech should make this Arp Pro Solist a very sought after and valuable instrument for the collector, band or studio.”

“I know very little about this piece besides that it doesn’t seem to be functioning, though the power light turns on.

Some of the sliders on the left panel are also very stiff and barely seem to be moving.

This is sold as is, it could be the simplest solder fix or something I am missing but I am in the midst of moving and don’t have time to find out for myself. ” Click here to visit listing on eBay

arp_pro_soloist “Arp Pro soloist powers up, works well with a few exceptions I will note. All notes play, however, the “aftertouch” isn’t functioning correctly. A tech friend believes the “aftertouch pad” is dirty as it does work for the high D note properly. I could have this unit fixed and sell it for more but I figure I will allow the buyer to either fix it for themselves or hire a trusted tech. Other blemishes are that there is one fader knob missing and ONE of the voices seems to not be working (I think English horn) (probably the knob since all the other wave forms are working correctly) some keys stick slightly (also probably a cleaning issue) but they don’t stick so much to not be able to use it as it stands now. If you turn the aftertouch off you’d never know there was anything wrong otherwise. Also the “high” output (RCA) Is loose. The bottom is intact (hasn’t gotten wet) (warning sticker intact) cosmetically it’s beautiful no deep scratches that I can find at all keys as well. I could give it a good cleaning but again I’ll let the buyer do that. All knobs move well. Some of the faders seem a little sticky (if I were going to keep it I’d probably replace with the nifty LED) fader upgrade available on eBay. Also in one of the photos it seems that one of the faders (first) is bent. This is not the case. The fader knob was “off” I replaced it and showed new picture. I just included both. Note that the faders as well as all the other controls function correctly. (Octave etc).” Click here to visit listing on eBay

pro_soloist “This unit just received a complete overhaul that took a whopping 23 hours (!). The filter module was defective, as is common with these at this point in time. Since many parts were going out of spec, we replaced all parts since we wanted it to sound like it should and to be reliable as far into the future as possible. We also recapped the power supply and power line, cleaned all switches and sliders and connectors, rebuilt the keyboard = replaced all bushings with new ones, cleaned key chassis, keys, bus bars, J wire key contacts, performed necessary repairs and, finally, recalibrated. This was a huge investment but the end result is an instrument that is in top working order and better than the rest.” Click here to visit listing on eBay

pro_soloist” You are bidding on an ARP Pro Soloist Model 2701 Synthesizer, s/n 27-924. I bought this keyboard new at Ace Music in Miami FL. back in the 1970’s (unsure what year). It has been in my basement unused for probably 25+ years. I just plugged it in and with some coaxing it worked! It will need some TLC (cleaning, minor cosmetic repair) but overall I think it is in great shape for its age. I will consider reasonable offers. Thanks for looking!” Click here to visit listing on eBay

“ARP Pro Soloist. Unit was modified but is currently not working. All circuit boards included. The power supply checked out good. I think the keyboard is good but I don’t know about the touch sensor. Keys are off white. Someone had a modification in it, I pulled it out but they put a pot on the front panel and drilled a few holes in the back. The pot board looks a little gnarly. the other boards look more or less ok. ” Click here to visit listing on eBay

“Zur Auktion steht hier nun dieser Synthesizer der Marke ARP “ProSoloist” mit einer Anleitung sowie einem Schaltplan und einem originalen Werbeheften aus der damaligen Zeit, achso und dem dazu gehördigen Notenhalter aus Acrylglas. Das Gerät wurde von meinem Onkel sehr gepflegt, alles ist noch original und wie neu vorhanden, sogar der Notenhalter ist noch mit dabei und ohne Kratzer.

Muss wohl laut Internet ein recht rares Model sein. Habe alle Tasten und Schalter ausprobiert, funktioniert offenbar alles einwandfrei, spiele selber Klavier, es kommen saubere Töne aus dem Gerät, habe es für einen Test extra an einen Verstärker angeschlossen. Mein Onkel hat diesen Syntheziser kurz vor seinem Tod (laut Rechnung im Dezember 2013) bei einem Fachmann zum Service gehabt.

Ein Service Heft mit Schaltunterlagen ist mit dabei sowie ein Werbeheft! Alles im guten neuwertigen Zustand!” Click here to visit listing on eBay

ARP Pro Soloist

“Good Condition

All presets works
All notes work

Had replacement power switch

New VCF installed by Phil at CMS a few years back. The new filter is the CMS brand. Some cracked PCB traces were recently fixed as the bad traces were causing some of the presets not to function. All function as they should now. Slider posts are broken off. I use a small pencil to adjust. The slider board could be positioned closer to the chassis or the shafts/sliders replaced for easier use of the sliders. These are rare and hardly come up for sale. Touch Sensitivity option is not working. These early models used pads that wore out rather quickly. Other options are available and I can recommend a good tech if you would like to explore them.” Click here to visit listing on eBay
