Hi there, another interesting guitar wiring is a Q-filter from Bill Lawrence.
I found this info over the internet:
Image
The Q-Filter is an LCR network - a 1 henry, low Q noisefree
inductor in series with a .02 micro farad cap in parallel
with an 8 kilo ohm resistor.
Any pictures, or schematics ?

I bought a blue Bill Laurence filter like that about 25 years ago. I couldn't get it to do anything useful. I didn't know about the cap and resistor though.
