I'm thinking of trying to make covers for the six I'm working on, but i'm not real clear on the the details. The cover ecloses the sides, not just the top, correct? One solid piece of wood carved out, or is it made like a wooden box? do you remove the metal (I'm using Bart pickups) cover, or does the wood go over it? About how thick is the top and sides, usually? Thanks all, you guys have been a great help, although I've learned so much in the short time that i've been here that the bass i'm working on has become a prototype, and i'm jsut going to start a whole new one when i'm done.
