Hello, I recently bought myself a cheap sevenstring and wanted to change the pickups. Now because in the past I struggled with soldering (my soldering iron is reaally bad) and the electronics in the guitar aren't great either i decided to buy active EMG solderless pickups and switch everything. Now i know that EMG pickups are internally shielded. Which means I don't need to shield the pickup cavities. Right? But I want to protect the inside electronics from outside interferences. By the way the shielding paint has been done very poorly. And this is where I am confused. I have read now that when shielding inproperly I will make the humming worse. And it is made inproperly when not connecting the shielding to the grounding wire. Does that mean I have to connect the copper shielding to the grounding wire that is connected to the output jack? If so how am i supposed to this? Or is it enough when the copper shielding is in contact with output jack? Edit: Will there also be any problems if the copper shielding is in contact with the pots and switch? I apologize for my sentence structure. English is not my first language. And as you can tell I have never shielded before but it's something I really want to do just to make the guitar perfect.
