Gerry Leonard, AKA "Spooky Ghost." Not very well known, but he's a killer session/touring guy...plays with David Bowie, Duncan Sheik, Suzanne Vega, etc etc. His playing style/sound is truly unique...I've seen him with a few PRSi, but usually a white Hollowbody.
Santana, Orianthi (great role model for my daughters), Alex Lifeson... I think, having grown up a Michigan boy, it would have to be Uncle Ted... He and Santana were the first PRS players I was aware of back in the day
