I have a MIM Mustang PJ bass. I tried different p-style pickups in it, and I want a brighter sound, with more upper mids and heights. I learned that real Mustang (rounded) pickups would sound exactly that way versus precision style pickups. I’m thinking about getting Duncan custom shop Mustang pickups. A couple of questions 1. Am I right about my sound assumptions about mustang vs p pickups? 2. Can I fit mustang pickups under covers from p pickups? 3. Any possible issues with string spacing, different positions of screws to mount pickups?
