Inside the guitars we started with making sheet copper boxes soldered together.
Chassis Ground = Shield
Signal Ground = Star/Buss Grounding
even though they DO connect/conduct together, they are 2 different things and should be classified as such. also, even though both can function without the other, there are reasons why they should be connected together.

But I still don't understand, even if there are two paths (connecting at the pot/shielding and at a wire/buss), the current will only flow down the one with least resistance, so the higher resistance connection is as if it is not there at all anyway because it won't travel down both if one has less resistance, true? That is if the pot to shielding connection is a higher resistance than the wire coming off of it to the buss. And if that was true, there would be no need to insulate the pot from the shielding? Just wondering and really don't know if that is true.
