Howdy y'all. So, I plan on upgrading the pickups in my bass, and possibly adding a preamp. My bass is a Squier Shortscale Jaguar, which has a P/J configuration. I play songs by Nirvana, the Foo Fighters, America, the Beatles, Two Door Cinema Club, and the list goes on and on. I have no experience with electronics whatsoever, and I don't want to break the bank. What do you suggest I do?
