Hey guys I’m having trouble with my pickups, everytime I touch my neck pickup on my fender Strat HSS it produces a loud hum, when I touch my middle and bridge pickups they don’t produce loud hum, I know it’s a grounding issue. But I’ve tried everything to fix, any advice. Any help would be appreciated. I don’t what I’m doing wrong, I have a video and posts posted to see if wiring something wrong, my ground screw and tremolo claw are wired to my volume, my output Jack ground is wired to the volume 1st lug of my volume pot, my output Jack tip is wired to my second lug of my volume pot. My screw that connects the shielding paint fell off, so I just soldered the screw wire and trem claw wire together to the volume pot. If I did anything wrong please in detail so I can fix it myself.
