how can it be measured, and what are some typical numbers on some Duncan pups??? Let's see who really does their homewrk

Re: gauss...
It's called a GAUSSMETER
There is a device called a "hall effect device" that can be put in a cheap circuit to measure this. Radio Shack USED to have one for a couple bucks, but stopped carrying it. Arrow has it, but IIRC there's a minimum order amount for them.
I wanted to build a gaussmeter, since retail ones are expensive, but this project uses the discontinued piece:

Re: gauss...
Besides a good gauss meter, it would be very difficult to get accurate gauss measurements without having a precise holding fixture to replicate your testing (due to the fact that magnetic field strength follows the ‘inverse cube law’).
This means that if you double the distance from a reference point, the field strength will decrease by a cube factor
Or another way to put it, if your gauss meter read ‘1000’ at 1mm from a magnetic source, it would read ‘10’ at 2mm from the source.
Think about that next time you adjust your pickup height...

Re: gauss...
Interestingly though, the output voltage tends to follow the inverse square law ... double the distance of pup to strings, get a halving of the voltage.
Off topic, but I've got an old BOSS rocker distortion that uses a hall element instead of a pot to vary the level of distortion ... kinda cool actually, wish they'd bring that back, no pot to wear out, and no pot noise.
