FYI, I just discovered a potential problem with the grounding wire on my Badass II.
The ground wire strands hade been fanned out towards the neck, but this lined up with the nameplate indentation on the back of the Badass II, so this meant the wires were probably only loosely touching the bridge. I simply oriented the strands towards the bottom and they are now clamped securely between the body and the bridge. I discovered this chasing down why my strings were picking up electical noise that went away when I touched the strings.
