Did you locate and connect the ground wire for the bridge?
Yeah, other humbucker guitar has no issues aside from a small amount of hum that seemingly comes across the amp sim regardless of what's plugged in (or not).

I've tried a number of ground checks, and nothing seems to have worked. Put a wire from bridge to pots, bridge to common ground, extra vol to common ground, etc.

That said, I had only tried bridge outside of coating to the parts, so that could be it. It does have a wire from the bridge post, but it's entirely possible that could have been busted on install, so will have a play some more with that, but otherwise it's as it should be in regards to the diagrams, with an added ground fix
