Guys...
Humbuckers that have coil taps.
When I switch to single coil mode, is the hum thats asscociated with single coils still there?...or because they have another coil right beside them has it been ...ummmm bucked? ;D
So I get single coil pleasure without the FUZZ!

Uh, gee Deep. In a word: No. In cut coil mode It is a single coil. Without a paired reverse polarity and revese wound companion coil to cancel out the RF reflection of 60 cycle AC occilations, you should hear hum. IF you can't hear the hum in unshielded cut coil mode, crank up the gain and it will be evident. Even with shielding you can hear it with additional gain. |

Thanks Rune.... I knew it was too good to be true.  |

About as close one can get to single coil pleasure with a 4 wire humbucker, is to switch the coils into parallel with each other.
Those of lesser wires cannot.

My new favorite sound is a humbucker, series connected, with one coil bypassed by a cap - of about 39nF (selected by experiment). It has the bite of a single coil and most of the weight and volume of the humbucker. It is partly humcancelling (not very much though - but I dont mind). I prefer it in place of a full coil cut on the bridge pup of my LP, which I found to be too thin sounding.

John, It's only partially humbucking, and it exhibits 'desirable' tonal characteristics because you've just instituted a parallel LC trap. That is to say, the combined reactances of the cap and the coil it's connected across form a filter, and when combined with the unbypassed coil, there's a notch in the audible spectrum..... which seems to be right where you like it!  (After all, you did tune it.  If one knows the inductance of one's pickup coil, one can consult various online calculators, and determine the resonant frequency of one's circuit. (And possibly the Q at the same time). This works well to avoid having to sharpen one's desoldering skills.  HTH sumgai |

Thats all true Mr S. I did do a little pSpice on this when I was messing with it, and with the quoted specs for my pickup (or actually half of them, for one coil), I do indeed get a dip at around 500Hz, which is quite tonally effective as a contrast to the full humbucker. It corresponds to the calculable resonance of an LC circuit comprising half the pup and the extra cap.
