I got a buddy that changed out his stock JP6 no piezo to have Seymour Duncan Blackouts. IT sounds good...he plays hardcore shed. His amp is a Mesa Dual btw.
I know a guy with PAF Pro's in a BFR. It sounds amazing.
I was all up for changing the pickups until I got mine, but the CL/LF set seems to follow me wherever I go, it doesn't rule anything out and actually suits me very well. It also doesn't have of those distinctive weird EQ shapes that mean it always sounds like a Crunch Lab, it's very flexible.
I wouldn't be disappointed if it came with PAF Pros though.
