I haven't heard the P90's in the Jr. yet. For my Artist, I was really pleased with the 59 combo it came with. And I like the Seths in the Newport pro. I can't stand the JB, never could, never will, it's like all harsh and no tone. Only problem I have is I hate to spend money on pickups just to experiment, Lollars, WCR, Fralins just seem to cost too much if I'm uncertain about them.
