I've just shielded both cavities (copper foil) and bottom of a pickguard (2 'cages' connected together). Do I need to solder a wire connecting shield and pot/jack (ground)?
Or is this unnecessary since output jack's in touch with copper foil under the PG? Is this grounded already, right? Also, where do I solder groundwire coming from the bridge? To back of the pot or to a jack's ground

I'm doing this on my P btw...
Please excuse my ignorance but I'm complete noob about electronics,...
