I'm not a fan of the P-46 I'm afraid. It sounds odd to me. The current Fralins are A2 and I wasn't thrilled either, it lacks steam in lack of a better word (I normally prefer A2 to A5 so I don't think it's that). My favorites for even, growly sound and some punch are the SPB-1 and the Lollar. I haven't tested all P pickups yet, though.
This is very taste dependent, obviously. I just don't like holes in the sound, I want an even sound, and I want something to happen when I play harder. Fralin obviously caters to people with a -say- fine taste. Well screw that I'd say
