Not a major DSO follower so I have no idea what JK might or might not have played years ago with them. The PRS's shape, though, did seem closer to this new-for-this-year NF3 model (which I saw with both rosewood and maple boards at PRS Experience this year, though the stock models are maple) than the older, classic shape. Can anyone else comment?
P.S. When I played the NF3, I thought immediately that it could work well for Jerry tones. And the neck is so comfortable.
EDIT: Gotta love Google Pics. Mystery solved - this looks to me to be an older discontinued EG.
