Anybody good at troubleshooting electronics? I followed the wiring diagram from the website for four pots (2 Volume & 2 Tone) and the pickups are hot. I have volume control and tone control for both. However... With the neck pickup volume pot turned all the way down I still get sound from the neck pickup unless I turn the bridge volume pot all the way up. I should mention that the cavity is shielded with copper foil and I went ahead and ran all the grounding wires in the diagram even though the directions said this might not be necessary. Not sure if that's the problem... I figured ground is ground. Here's a photo of the wiring diagram I followed. Help, I'm stuck!
