Hi all.. dont know if this is covered anywhere else. I have an 08 USA P bass - Thinking of swapping the PU. Anyone do it? bad idea? if So what did you get? I am looking for something big hot and gritty sounding. years ago I had a P with a SD 1/4 Pounder in it... it was ok but wondered what else is recommended. Maybe the "hot" P bass model? Opinions Welcome and Appreciated!
