I know this was part of another post I started, but there have been no replies with that title Anyway, is it ok to do some route and soldering work and put in some different pickups? (ie: using a P body to put in J pickups) I know Mr. Hoppus has made his J bass into a J bass with P pickups, but this was done by pros. But who knows, maybe I'll bring the new pickups and the bass to the shop and let them do it. I just need to know if it's ok because I just got a battered up Fender musicmaster and I want to replace those pickups with either a J/P, P, or J configuration. Any hope of doing this with a short scale successfully???
