UPDATE: The guitar sounds perfect and awesome w/ the new pickups, with one minor caveat.
I think I might have fried one of the switches. For those of you familiar with the Fender Lead II wiring
found here, the Lead II has two switches--one a normal pickup selector, and a two-way switch that changes the phase of the neck pickup. On one position the phase is normal and with both pups selected you get a normal two-pickup tone. Switch to the 2nd position and you get a nasal, out-of-phase sound.
The guitar sounds good in the out of phase position but when the phase is normal I get a crackly sound out of the neck pickup. What did I do wrong? Fry the switch? Bad soldering? Fuck a guy?
EDIT: I checked the wiring of the switch. I've drawn up what it's supposed to look like:

Now I think that the diagonal connections which essentially do the phase thing--those wires must have gotten fried, considering how badly brown and burnt they look. Will it solve the problem to re-do it with new wires or just get a new switch?
Also, Seymour Duncan lists a
different way to do the phase reversal switch.
