Following up on vein of a recent post on p-ups I found this article interesting:
http://www.moore.org.au/pick/04/04_lgen.htm
seems to me it's one of the few on the web talking engineering rather than sales speak.
"Electromagnetic guitar pickups are very poorly understood. This sequential lateral engineering analysis shows how they really work, how to shape the spectrum for any pickup and blows the sales myths beyond reality into figures that are highly predictable! "

Re: The pickup as a generator
Thanks! I have been looking for something like that for a long time. Lot's of info to dig...
Have you taken a look at the other papers? You gotta love digital filters applied to market stock trading data.
Your L transform siggy is gone?

Re: The pickup as a generator
thats a good one........ its good to see a study with results and a conclusion
loading is very critical...... you can brighten a dark sounding pick up and
darken a really peircing top with proper loading..... carvin used to put a 2.2M
input resistor for exactly these reasons.... change the loading change the tone
the graphical presentations are very practical .... the only confusion I found
was what is ment by "lateral humbucker"... I assume side by side....
and this statement:
"it would be entirely possible to have a load switch or potentiometer in a guitar that in by changing the resistance of the load changes the upper 3 dB cut off point in the spectral response of the pickup - as though you were changing pickups! "
seems to decribe an old fender patent for a pickup arrangement in a lapsteel

Re: The pickup as a generator
Actually I'm unsure as to his comments and conclusions on series connection of humbucking coils. Also as he seems to prefer parallel arrangement and makes no mention of reverse pole orientation or noise I'm wondering if he's missed the point of Seth's invention. But I can't claim to have fully digested the article yet.

Re: The pickup as a generator
Haven't read it all either, but you might find references of the noise reduction as he makes a brief mention of the humbucking principle in the introductory article http://www.moore.org.au/pick/01/01_strt.htm (search for Humdinger).
He seems to treat the distant field canceling as a rather trivial aspect compared to the rest... might explain why we don't get much more than that.
He also uses the term "aiding" in the conclusions of http://www.moore.org.au/pick/06/06_gobd.htm. Is this related to the hum canceling properties of an arrangement?
Fantastic find!
