I could be wrong, but I believe they used the duplicarver to the early 2000's. Anyone who know for sure is welcome to correct me. I have a 92 Custom 24 with gold hardware in very good condition. It's the only guitar I get nervous on taking out to a gig. It's a wide thin, but it feels different from every other PRS I own or have played. I live in Maryland, so I've been able to handle a few.
