I know call me nuts, I have a USA P Bass which has the S-1 switching I dont care about. Anyway I love the Bass dont care about the pickups. I cant afford another bass right now so I thought about swapping out pickups for something like S.D. Quarter Pounders but which ones I want a deeper little more bottom. Are some other pickups. Some told me I could do this with a pedal, like a Sansamp are something running it tru the effects loop are in front of the amp. I use a SWR 750 WorkingPro Head SWR 410 cab. At one club I Play I run out of my head tru the P.A. tru 18s that what they make me use and on the stage I have a 210 monitor and a 15.
