Ok, first off let me say that this may well be placed in the wrong thread. It could be better for electronics or something else, but I'm not sure, so I put it here. Mods, feel free to move it if nessicary. Ok, I read something the other day that said the Yamaha SG2000 guitar (SG syle copy) had a brass block placed under the bridge for added mass and sustain. How well would this work on bass? Would it mess with your electronics at all? What about with a piezo bridge?
