Re: Hybrid of Neck and Bridge Pickup?
Absolutely worth it. Unmatched coils is one of the factors in the original 1950's PAF's legendary sound. I do exactly what you're talking about to make a neck hybrid: a coil from a bridge PAF with a coil from a neck PAF, they can be the same model or different models (i.e. '59B/'59N, '59B/SethN, etc). The difference in resistance between the coils is enough to let some single coil sound come thru, which adds high-end and reduces midrange, which is what I want in a neck HB (when coils are evenly matched, the 'humbucker effect' cancels noise, reduces treble, & adds mids). As far as the impact of the wind, who knows? Those are trade secrets that PU makers don't share, so we have no idea how much alike or different the wind patterns and tensions are.
The difference in coils between a bridge & neck PAF make a hybrid brighter, even though the combined resistance of the coils is higher than the stock neck PAF used in creating it. For me, that means I can use a warmer unoriented magnet for the added texture (A2 or UOA5) and still have increased high-end and clarity. In the case of stock neck A5 HB's, a hybrid with a warm magnet will also dial down some the excess low-end that some of them can have (the '59N is known for that in some guitars/woods).
Using two coils that have a similar resistance will most likely have subtle differences compared to the parent PU's, too subtle for me (again, who knows what the winds are). To go to the trouble of making a hybrid, I want a clearly discernible difference in tone.
For bridge hybrids, you don't need the huge difference that the '59/Custom has (7K vs 4.2K) to get the benefits of a hybrid HB. It's kind of overkill. 1K difference is plenty, and with that, you may want a warm magnet to tame the treble. For example, a coil from a 14K bridge HB with one from a 12K, or a coil from a 10K with one from a 12K. Try them with the stock magnet and see if the EQ needs to be moved in another direction.
