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.

Guitar is in almost mint condition, but is missing knob cap for master volume as it had been epoxied to the old pot which was bad and had to be replaced. Will supply replacement cap but it will not be NOS.
