Hello Everybody im new to this site but i am hoping people could help me out on a dicision of mine. In compensation of my decision not to buy a new bass i decided i will fix up my current bass (the Fender P-bass) since i hope to be playing a lil more than by myself. it will make the bass oh so more special to me. I like to do things on my own and very capable of sodering and such so no worries there. I have been looking at pickups (EMG) and will test out active vs passive, but here is the big question for you all. if i go for active i will need a place for the battery, would carving out a section of the body under the pickguard have any effect on my bass?
