I'm on a gear buying frenzy this weekend, just ordered a Sansamp RBI and QSC RMX 1450 power amp, and now I'm tossing around the idea of eventually upgrading the pickups in my Fender P-Bass. Trouble is, I've never done this, and frankly don't even know where to begin. I've got a 1996 MIA P-Bass with the stock pups in it. I play primarily metal and rock music and would like to hear what other pickups you guys might suggest I consider. Mainly I'd like to get an idea of what's out there and what different tones I might expect from them - focusing on classic rock/modern rock/metal styles. I'll add that I like a classic/vintage tone - something dirty and growly with lots of full bottom, but also with some punch. I know I can dial a lot of that with the RBI, but I'd like to hear about any pickups that can help it along as well.
