I am trying to assemble a jazz bass using this body and i noticed several things that called for moding the body. I dont want to mess up the body in anyway so i came here for help. I need help on the following: 1. Grounding the pickups. (i heard something about using a router from a freind) 2. Installating the pups 3. The bridge....I know that i have to measure 34inches from the nut but I am uncertain of how i will be able to make sure it is postioned right. Im new to all of this so please help me out so I can start ASAP!
