GR-500

“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!!!!
