“This is it !!! “the” original Roland GR-500 analog synthesizer unit from about 1978 or 1979. I have had this stored in a suitcase for about … oh 30 years. (maybe more) so… Time for me to part with all this stuff I have collected and never ever used so keep an eye on my other auctions in the near future but this one is a good start!
You know something is pretty cool when it has it’s own Wikipedia page. 🙂 check it out for more info on these!!!!

“This auction is for a fully functioning Roland GR 500 system including GS-500 guitar and additional broken gr-500 parts donor. Guitar and floor unit were serviced and calibrated but one of the custom made potted chips roland used to track pitch into voltage was bad, i obtained a broken gr500 from which one of the chips has now been harvested to make the gr500 fully functional leaving you with 5 spare chips, pots, sliders, knobs etc to allow servicing for years to come.
This is one of 200 produced (or one and a half!) extremely rare guitar and synthesizer. Guitar has built in infinite sustain system and active electronics to interface with the floor unit. Connects via special locking 24 pin cable, included and serviced.” Click here to visit listing on eBay

“Hallo ebayer und Roland-GR Fans,
ich löse meine GR-Sammlung auf und zum Verkauf kommt der Dinosaurier der Gitarrensynthis GR500. Er läuft mit 110V und stammte aus Amerika als Restaurationsobjekt. Ich wollte einmal im Leben eine Legende spielen und hören. 🙂
Der Techniker Eures Vertrauens wird sicherlich die 2 Fader (siehe Bild) erneuern und hat sicherlich Knöpfe um den GR500 wieder schön aussehen zu lassen.
Ich hab das Gerät Gerät in die Kategorie Ersatzteil/Defekt eingestuft, obwohl es läuft. Will auf diesem Weg direkt klarheit schaffen, zumal bei diesem Alter alles möglich ist.
Eine seltene Gelegenheit solch ein seltenes Gerät ab 1 Euro zu ersteigern. Nutzt Eure Chance!!
Ich akzeptiere ausschliesslich Ãœberweisung oder Abholung. Kein paypal!” Auction ended. Click here to browse on eBay.

Description:
This is THE first guitar synth ever made & it came out in 1977! As used by Mike Rutherford of Genesis and Alex Lifeson of Rush.
GS-500 Guitar:
* Ibanez made Les Paul type guitar with tons of knobs to control various parameters of the 3 separate synth’s that were built in to the GR-500 module. The GS500 was a heavily modified Ibanez guitar, with a single humbucker plus a hexaphonic pickup for driving the GR500, individual on/off switches for each of the four synthesis sections, switches to select the sound of the guitar itself, the synthesizer, or both simultaneously, plus EQ
* The guitar utilizes a special pickup system that is connected to the synth module via Roland’s own 24-pin interface and controlled it using CV/GATE signals generated by the guitar’s pickup system while playing the guitar. In addition to the modified pickup, there were magnets under the face of the guitar that could increase its sustain.
* All this appeared as a beautifully crafted, but very heavy instrument whose body contained magnets that fed the audio output back to the strings, thus creating an ‘infinite sustain’ system. The GS500 really was far more than just a guitar plugged into a sound generator!
* The guitar has a very nice honeyburst finish.The playability is very good, with a nice comfortable neck and low string action.
* The sound is very very very versatile as you may expect. You can create anything with this one, Because of the Les Paul style body this guitar sustains for days and has a nice warm tone. I’m sure the guitarsynth experts know what i’m talking about.
The condition is good. Just light playwear. A hardcase is included for the guitar.” Auction ended. Click here to browse on eBay.
