The adjustable pieces go toward the bridge on the bridge pickup and toward the neck on a neck pickup, right? So what's the effect if you reverse the pickup so the adjustable poles are toward the bridge on the neck pickup and toward the neck on the bridge pickup?

Yeah i want to know what this does too.

If you have the pole pieces absolutely flush with the surface of the bobbin (just like the slugs on the other coil), it won't make any significant difference at all.

But if the poles are raised at all above the surface of the bobbin (as most of us have them), the polepiece bobbin will be more dominant in shaping the tone. And for an obvious reason: The polepiece coil brings the magnetic field closer to the strings than the slug coil does.

The reason for the standard set-up having the polepiece coil face the bridge on the bridge pu and the neck on the neck pu is to create more contrast between the pickups and also allow you a wider range of tonal adjustment. The bridge pickup by virtue of having the pole pieces facing the bridge is made brighter the higher you raise the poles, because the closer to the end of the string (bridge or nut) you get, the more treble you get. And it's the opposite for the neck pu: The closer to the middle of the string (12th fret) you get, the more bass you get.

Spinning your pickups around 180 degrees will result in a bridge pickup that's less bright and a neck pickup that is less fat -- again, assuming your poles are raised above the surface of the bobbin.

All right. Makes sense. Thanks a bunch.

so if i wanted a little more warmth from a 59 i would spin the pickup around so the screws are more twads the neck and then raise those screws a little?

Lower the pickup then raise the screws?

I have a lynch screamin demon i feel its a bit to brite, so i could lower the pickup and the raise just the neck coil screws? put the bridge coils down flat?

Bower, your right! you get less brite high strings. But be careful with the g string getting too high, just to get an even response of the strings.
