“Physically in very good condition but it got some issue with the sound. I’ve been looking for a good technician for over a year now but there is none where I live. So I’m givning up and selling as is.

All knobs, buttons, sliders, keys etc works as they should but the sound comes out ”broken” like it’s a constant white noise over the wave forms. Sounds more when you open up the filter. Probably just need some component replaced inside.. should be a fairly easy job if you know what you’re doing and where to look. I’m better on the outside of the instrument..” Click here to visit listing on eBay

“Roland Promars Vintage Compuphonic Analog SynthesizerGreat condition, works well I’ve used it for making tracks multiple times all the modes and effects / VCO etc are working. This is a Vintage synth so if you’re looking for a brand new stuff that’s not for you, faders can be a bit rusty or capricious but overall I’ve not had any issues with it. Again I’m not an expert I have quite a few vintage synth and use them all casually so if you need a perfectly accurate diagnostic of the synth I cannot provide it. Visually on the bottom left you have some discoloration otherwise as you can see on the pictures it is pretty clean !” Click here to visit listing on eBay

” Selling a nice example of the quite rare Roland Promars. Recently serviced by Synth Service in London ( paperwork available) and in full working order, including the CV ins. Missing two screws to the bender panel ( see detail pic) but this is still solidly attached and has never bothered me in use. Easily replaced if you want. Panel is in very nice condition I’d say 8/10. Wooden end cheeks have the odd scratch but nothing serious, I’d say 7/10. See photos.” Click here to visit listing on eBay

Even though it has a North American plug, you MUST use the included power converter!!!

Failing to use the included power converter with ruin the synthesizer!!!

There are multiple areas that have minor but noticeable wear!

The bottom of the unit has very noticeable wear!

A couple nicks on the wood panels.

None of which affects the functionality!

100% fully functional!” Click here to visit listing on eBay

“If you’re looking at this, then you know what it is. I recently bought this from a real ‘synth guy,’ who went over it and serviced it… made it good for years to come. He replaced the battery, re-capped it, and cleaned it up. If you’ve been looking for a great Promars in very good-excellent condition, then this is the one… Also probably the only one available online that ships from inside the United States. It is in 100% perfect working condition.

In the interest of full disclosure, here is a fully transparent (to the best of my ability) description of the synth’s condition, with any and all ‘little’ things that one would want to know:

All original sliders, knobs, buttons, switches, etc. are present and accounted for. There is no writing or stickers anywhere- as far as cosmetic condition goes, there are some knicks on the wooden sides (visible in pics), a little bit of tape residue next to the word “Promars” on the face plate, and a little bit of rust/buildup on some of the screws (which could easily be replaced). Also, the Attack slider in the VCF section is slightly bent, but does not affect function. Synth stays in tune and tracks well.

Also, this is the Japanese version (100V), so you may want to get the appropriate voltage converter for this baby.”

“Overall, the synth is in superb working condition. The front panel is very clean, with hardly a mark to be seen, just small blemishes. The wooden side panels are really tidy with only minor marks. The back panel is very good with only minor marks to the paintwork.

All knobs, sliders and switches are present, original and function correctly.

The unit has been fully tested and the oscillator tuning and scaling confirmed. A new memory battery has been installed. ” Click here to visit listing on eBay

pro_mars “Hallo zusammen!

Ihr bietet auf einen “Promars Compuphonic MRS 2” Analogsynthesizer der Firma Roland. Der Synthesizer ist gebraucht und wurde von mir ca. 1998 erstanden (Baujahr “Vintage Synth Explorer 1979 – 1982 http://www.vintagesynth.com/roland/promars.php) und steht seitdem in meinem Nichtraucher-Haushalt.

Ich bin leider kein (Vinatag-)Synthesizer Expert, glaube aber, dass der Synthesizer für sein Alter in sehr gutem Zustand ist. Alle Regler, Potis und die Speicher-Funktion funktionieren.

Sooweit ich das beurteilen kann, ist der Synthesizer im Originalzustand, lediglich der der original “VCO-2 A-Tune-Off-B-Tune”-Schalter (zu sehen auf dem fünften Bild unten in der Mitte) war abgebrochen und wurde von mir durch ein original Ersatzteil ausgetauscht.

Der ersetzte Schalter war Teil eines Reperatur-Kits dem auch eine Batterie beilag. Ob diese für den ProMars ist oder für das Schwestermodell Jupiter-4 ist mir leider nicht bekannt.

Der Synthesizer ist für heutige Verhältnisse extrem massiv und groß (Breite ca. 77 cm, Tiefe 40 cm & Höhe 17 cm), dies ist auch der Grund warum ich mich schweren Hezens vom ihm trenne: Ich brauch’ den Platz :-(” Click here to visit listing on eBay

“Ein echter Vintage-Synthi ! Keine mehr oder weniger gut gelungene programmierte VSTi-Adaption. Ich trenne mich nach gut 30 Jahren von meinem Synthi. Andere Projekte stehen einfach im Vordergrund. Der Synthi ist voll funktionsfähig und sofort spielbar. Einzig der Zahn der Zeit hat ein paar Spuren hinterlassen. So sind die echtholz-furnierten (!) Seitenteile leicht zerkratzt bzw. an einer Stelle ist das Furnier beschädigt (s.Bild). Der Tuning-Regler bräuchte mal etwas Reinigung. Der kratzt leicht. Ein paar mal hin und her drehen und es klappt wieder mit der Stimmung. Die Stimmung (ich meine die eigene ;-)) steigt sofort beim spielen. Was da ‘rauszuholen ist zeigen die wirklich gut gelungenen Seiten ”
