The guitar that Richie is playing in his instuctional video is a modified RG570. The electronics and hardware are just about identical to the early Jems, with the addition of a coil tap switch (the
toggle switch by the
neck pickup).
After Richie stopped endorsing Ibanez, he sold the guiar to one of his students, who sold it to the Sam Ash store in King of Prussia, PA. (I played it there about two years ago). I was tempted to buy it, but didn't. It still had Richie's name in script on the headstock.
The going price was $650, no case.
Cheers,
Butch
