I want to replace the pups on the MIM Fender Jazz, but I usually use the bridge pup for a growly sound. Can I replace just that pup? And by "can" I mean would it be wise and reasonable? I don't have much money, and if buying one is really all I need then I'd love to save ~60 dollars. Plus, I've heard that on newer Fender Jazz models the Bridge pup is the same size as the neck pup. Would this mean I should buy a neck pup for it or are the wirings different? Sorry if these are stupid questions, but I'm semi ignorant of bass matters.
