PRS McCarty, employee model. After someone worked at PRS for a while they could have a guitar built with their choice of woods, colors, features etc. Being in Maryland I've seen lots of these over the years and they've all been at least as nice as other production guitars. This one's in excellent original condition from top to bottom, front and back, even the gold hardware is largely intact. Serial number puts it in either 1997 or 2007.
