I am rebuilding a 4 string P-bass into a fretless. So far I've had added in a bone nut. I have some questions on pick-ups. I just wanted a few suggestions on some decent pick-ups that would sound nice playing fretless. If you have any advice on a bridge that woud go well with it than that would be great. And also my knobs on the bass are a crappy. They keep on turning but work. But about the wiring, I want to replace the wiring kit. How should I go about this? Any one that has had experience with this kind of work please feel free to throw in some advice. I would really appreciate it.
