I see your point,
but the issue with the cavity isn't the wiring, its that the wood is literally chiseled out on part of it and there is some shielding missing. there is an intermittent buzz also, perhaps coincidence.
The pickup doesn't have a tilt adjustment, just two screws total per pickup
Raising pickup height isn't going to help with the volume issue since the volume fluctuates and drains batteries at an alarming rate.
as far as the imperfections in the wood, the guy at Ibanez even admitted that the finish looks like it was implied improperly resulting in a crack and bubbles in the finish.
