Hey guys, I did my due diligence performing a search on this topic, and I'm sure this information is out there but I couldn't find it. I've been reading up on star grounding and proper shielding technique, and everything makes sense to me except one element. If the body of the output jack is electrically connected with the grounding lug (which most, if not all of them seem to be), then wouldn't star grounding to the output jack create a ground loop in a shielded cavity? It seems one would have to isolate the output jack from the copper shielding in the control cavity, otherwise you have your star ground point on one side of the loop, and the pots/switches also grounding to the shielding in the cavity, which connects to the output jack on a separate path. The problem is, it doesn't seem like anyone's isolating their output jacks. So what do I have wrong? Thanks for the help!
