On http://www.guitarfetish.com I looked under electronics and then under this guitar modding thing where they give you 13 way switching. The positions for each pickup were off, Phase on, and phase off. What the hell is phasing and which one of those gives you the normal pickup sound? Can sombody pleas explain the difference between phased and not phased sound?
By itself, a pickup won't sound in-phase or out of phase. You know basically how sound waves work right? Two sound waves 180 degree's out of phase (the opposite) cancel each other out, and two sound waves in phase will combine together to make a stronger wave. The same basic principal works with guitar pickups. If two pickups are wired in series, and they are wired in phase, the sound gets louder. This is basically position 2 and 4 on a typical Strat. If they are out of phase, the identical sounds cancel each other out, and you are left with only hearing the difference between what the two pickups will sound like, normally a thin, weedy sound.

Actually position on 2 and 4 on a typical Strat on cancels out the 60Hz hum that is inherent to to single coil pups. Works the same as a humbucker, reverse polarities cancel each other out.

If you reversed the polarity of the middle pup, then positions 2 and 4 would be out of phase.

Oh. I was thinking that was the aim of having a reverse wound middle pickup, like the reverse winding and the wiring out of phase cancel each other out, meaning you get a stronger signal, plus less hum. Feel free to correct me if I am wrong, that's what I was taught by my guitar teacher.
