I've got a Squier P-bass "Special" with P/J pickups I use as my backup / beater. It actually feels good and plays nice (after a neck shim and some other tweaking), but the pickups are kinda grainy and flat sounding. Is there anything out there around $100 worth getting? I've had good luck with GFS pickups on guitars, but I've never heard anything about their bass pickups. I'm concerned that buying separate, unmatched pickups won't blend well. Any input is appreciated, thanks. Oh, and the search function won't work with "P/J"- I already tried, sorry.
