Cool, cool. Just one more thing: Will using a coil tap change the tone when it's switched off? As in... Would a humbucker sound better without a coil tap installed?
Do you mean split? Coil tap is when you take a feed off the coil part way through the winding process so you can get 2 different outputs (say one at 6,000 winds and one at 7,500). Coil split is when you have 4 conductor wiring and can have series/parallel/screw coil only/slug coil only wiring.
In the first case the pickup will have to be made specially to do this, and I don't know of a humbuker with it as you would need 6 wires off the pickup (unless you only tapped one coil, but then it would not be a humbucker any more). Usually coil tap is on single coil pickups - the PRS 513 has this I believe, but it uses 5 single coils in different wiring.
When you get 4 conductor wiring, there is no sound change in series from 2 conductor, you are moving the connection of the coils about 8-10 inches (whatever the length of the lead out wire is from the pickup), but that will make such a small difference that you won't be able to hear it.
