Negative Feedback Loops and the Fender Presence Control

In my 50 and 100 watt builds I use a 5K pot with a 4K7 resistor and a .02 uf capacitor tied in to the 4 ohm output transformer secondary lead.
 
I've got a heavily bastardized JCM900 2100 mkiii that I jacked the NFB resistor up to 133k. Works great in that amp.
