Oy i'm back. I've got another question. I was talking to one of the guys at the local Ken Stanton and I asked about jack plates and if they were absolutely necessary, he said "No, as long as your wiring is grounded somewhere else, like to the bridge". I've only ever heard of grounding/earthing to the bridge but is grounding to the jack plate an option? Could i ground it to any random bit of metal, say a embed a nail or screw into the electrical cavity, could i ground it to that if its not touching any hot wires?
