I've read a few threads that touched on this, but I wanted to get a little granular. I have a good sample of a new MIM P Bass, and upgraded the pup to a Fender Original (62), put in CTS pots, and changed the cap to .1uF. Sounds pretty nice to me, but without trying every other pickup out there, I don't know if I could do a little better. I don't mind experimenting a little, but would rather not buy a bunch of boutique pups and end up with the the same tone. I like the old Jah Wobble PiL sound, which I know is largely in fingerstyle and recording technique (amp pointed at the wall, I've read), but I'd like to optimize the bass itself, while I'm still excited about customizing . What specifically would I gain (or lose) tonally by moving to something like a 63 Fender, 58 Fender, Fralin, or NP4? I know it's difficult to describe in words, but given the target sound, is there any room for improvement? I'm currently using Labella DTB flats, medium. Thanks in advance for indulging a somewhat vague question!
