I installed what I thought was a Seymour Duncan EVH pickup in the bridge position and wired it directly to the volume pot. It's the type with only two wires, a hot wire wrapped in a wire mess ground wire. I haven't been able to find any diagram to match what I'm trying to do. So I winged it. Unfortunately a constant loud humming sound is being generated at any volume. Is this a grounding issue or something else? Tia Cowboydog .
