Gentlemen! I have two questions as a first time newly SERIOUS bass player! 1. Recommend me a good Fender P-Bass type pickup to drop into a good playing, but okay sounding, bass. 2. I need a gig-worthy amp that sounds good but won't necessarily break the bank. I'm looking to do the $500-$800 range, either combo or head/cab combination, used or worn is fine. I'll be playing indie/rock/pop covers (rock-radio type songs) but I want some versatility as well (jazz-ish type things, but I understand that may come more from the pickups than anything). Thanks in advance! Help a brotha out!
