Hoping someone can think of what to check next... Have a peavey grind 5, factory passive pickups. When I open both volume and both tone pots full on, I get a buzz. If I touch the ground jacket of my cable, it almost goes completely away. Figuring it was an emi or ground issue, I completely shielded everything: behind pickups, control cavity, and connected all the shielding to ground. While I was in there, I also replaced the pots with bournes. Had it all out anyways, figured why not. Even after all that, the exact same issue still occurs. So, any thoughts on what to check next? Maybe I just have really dirty power to my amp or something?
