Re: True Humbucking
If you're talking about the coils of a humbucker, they're wired internally, out-of-phase. Because of the way the magnet lays under the poles, each coil has reverse magnet polarity, thus bringing the output voltage of each, back into phase.
Hope thats what you're asking.
Edit: Of course, if its a 4-wire pup, you wire them externally out-of-phase by tieing the red and white together.

Re: True Humbucking
as I've understood, they must be coupled in phase
The SD booklet says the following:
Adjustable coil
Green = beginning (south)
Red = end (south)
nonadjustable coil
black = beginning (north)
white = end (north)
to get standart humbucking you have to connect red & white toghther, green goes ground and black is hot.
that would be:
beginning(north) -> end(north) -> end(south) -> beginning(south),
which looks like out of phase (begin->end->end->begin).
but if you consider, that south and north are reversed polarities they are actually in phase.
don't shoot me, if it's wrong, just what I understod...

Re: True Humbucking
Thats my Q.
Yeah I understand that and thats how i wld wire all my humbuckers, I just wanted the correct tech know how.So when I wire them :red & white toghther, green goes ground and black is hot. I am actualy wireing them Siroes (but obviously ofcourse ) out phsae? or series In phase?grams said:

Re: True Humbucking
The two coils in a humbucker are wound the same. So you connect them out-of-phase. (Red/white together.) Any external AC noise impacts the two coils the same. Since they're out-of-phase, the noise cancels. But, since the magnet lays with its north pole against one set of pole-pieces, and its south pole against the other pole-pieces, the string generates an out-of-phase voltage in both coils, which adds together in-phase, since the coils are out.
Does that make sense? :laugh2:
Look at this pic of a Custom that I took apart. You can just barely make out that the white wires come out of the top of the pic, and the black wires from the bottom of the coil:

Re: True Humbucking
LOL :laugh2: Yeah that does, so in short when I connect the red and white wires ground the green and the black is hot out put. I have connectted the coils of the pup out of phase with each other ( which they already are since the magnet lays with its north pole against one set of pole-pieces, and its south pole against the other pole-pieces). So they are actually at the end of all of it (like a sum in an algebra equation where - and - = +)In phase with each other. :laugh2:
By the way that custom is cool i am going to rip apart my stock pups too.
