Resistor Placement Question:

What makes the mod in the OP a little different is that it is usually done by connecting the pickup hot lead (either at the volume pot input terminal or the switch) to ground via the resistor. In the example posted in the OP, the resistor is connected between the volume pot wiper and ground, not the volume pot input and ground.

Which accomplishes what exactly???
 
I'm not sure it makes much of a difference, honestly.

It's just something that jumped out at me when I saw your pics.

It would be interesting to swap back and forth to see what, if any, difference exists.

I did...

I recorded back to back phrases. With resistor in place - as shown in OP - there is a very slight reduction in high frequencies.

That's it...

So, you tried playing with the resistor connected to the input terminal of the volume pot and then with it connected to the wiper terminal of the volume pot?

Or, was your comparison done with the resistor connected and then disconnected?

I never moved it from it's original position on the middle lug, but I tested with it soldered in place, then unsoldered the ground leg....

It changes the way pot, acting as a voltage divider works (pickup voltage leaving the pot at the wiper). Here's the calculations assuming a linear pot and a 1 voltage signal from the pup (not realistic, but makes the calculation simple). Think if the numbers in red as a percentage of the real signal.

That's awesome!!!!!!!!!!!!!!

Well, I tried something like this out on my Strat yesterday. I soldered a 220K resistor across the bridge pickup. I connected one end of the resistor to the switch where the hot lead from the pickup connects to the switch and the other end to ground (soldered to the back of the volume pot).

Initial results are promising. The output of the pickup doesn't seem to have changed and the essential tone of the pickup is pretty much the same, but the high-end, "ice pickiness" seems to be less. I need to keep testing under different situations and I need to play live to get a better sense of it, but so far I'm optimistic.

Plus, it gave me opportunity to change strings and tweak intonation!

Just exactly what Bill Lawrence said it does...

PRS used a 3.3megaohm resistor between bridge pickup hot and ground on their 2009 Nitro Series guitars.

Think about those numbers!!!!!
