Despite the RG name, the RG650 has the rounded-edge body style and swoopy, rounded headstock of the older Roadstar body. It has a tone chamber routed out of the body beneath the pickguard. The RG650 features a basswood body bolted to a maple neck with a 24-fret rosewood fingerboard with dot position markers. Components include Ibanez pickups with an IBZ humbucker with Duo-Sound coil-tap functionality at the bridge and Super 7F single-coils in the neck and middle positions and an Edge double locking tremolo bridge. The RG650 was offered only in Japan and was discontinued after 1986.
