Re: 1 humbucker out of phase with itself?
This always tends to be one of the most confusing of questions when it is answered. Pretty much, there are two signals being discussed here - desired and undesired.
The undesired signal is the hum or noise picked up from outside sources. The humbucking pickup is wired in such a way that each coil picks up this sound "out of phase" with respect to the other coil. The two signals are subtracted from each other and cancel each other out.
The desired signal is the magnetically induced one from the vibration of the strings through the magnetic field of the coils. Here, the coils are wired such that each coil picks up the signal "in phase" with respect to the other coil.
For the purpose of this explanation, we will focus on the desired signal.
When two identical pickups (or coils) are out of phase with each other, the sounds from each are subtracted from each other, If the coils are very close to each other, you will get a very thin and very weak signal as both coils are seeing almost the same signal (albeit in opposite phasing). As the coils are positioned further apart, the difference between the signals each pickup senses is greater, yielding a stronger but still thin combined signal (still not nearly as strong as "in phase").
Some people find the out of phase sound to be a useful one. It tends to be more pronounced and useful when you are using two separate pickups (for example, bridge and neck, bridge and middle, etc) than when trying to use the individual coils of one pickup. If you reverse the coils of one pickup, you will also increase noise.

Actually, ... The *hum* is picked up in phase and the *signal *is induced out of phase (per each coil) ... When the coils are connected to invert the phase of one coil, it puts the *signal* back in phase, while putting the *hum* out of phase .
