Re: Pickups for Yamaha Pacifica?
This raised a doubt in my mind...
Isn't a (full sized) humbucker hum-cancelling because the coils/bobbins are wired on opposite directions AND the magnets are on opposite polarities?
My electronics engineer mind tells me that!... Though I might be wrong.
Its a common misconception.
There's three things you can do to a pup to make it out-of-phase with another:
1. Wind it the opposite direction.
2. Reverse the magnet.
3. Reverse the hot and ground wires when you connect it.
Each one of those will reverse the phase. So, if you do two things, any two, you reverse the phase, then bring it back again. An rw/rp pickup is wound the opposite direction, (phase reversed), then has the magnets installed backwards, (reversed again). Thus, its in-phase.
Thats how it gets its noise-cancelling function. The noise in the air doesn't care about the magnets. Only the coil of wire. So by reversing the wind direction of one, the noise thats picked up out of the air is out-of-phase and cancels.
