Hi Folks I've just finished shielding the cavities. As I understand it, I need to connect them all, and plan on doing so by soldering wires from each cavity to the control plate cavity. The bridge plate will be connected via the copper strip that is extended to make contact with it, removing the necessity for an additional wire. Assuming this is sound, do I only need one ground wire to ground this circuit directly to the output jack? I know I can also ground to the volume pot, along with the ground wires from the pick-ups. Appreciate the advice.
