Re: Stupid question bout 5way selector?
To answer your question, it will produce a similar result (lower output and a thinner, more biting sound), however the process is completely different. You can think of a humbucker as two pickups, wired in series. Splitting the coils is when you only run one of those pickups.
A single-coil pickup, on the other hand, cannot be reduced any farther, so you lower the output and increase the treble by shortening the coil. That is what is meant by a coil tap.
BTW, I've never heard of a humbucker set up to actually tap the coils--correct me if I'm wrong?
