a better treble bleed(bright cap) circuit?

on the guitarnuts forum, someone recently posted a new way to implement a treble bleed circuit using a cap, a resistor, and a dual potentiometer. the idea is, to properly emulate the frequency boost you get from the inductance of the coil in the pickup, even when your volume is rolled back. you can find the schematic, complete with frequency plots for a number of different treble bleed circuits HERE. now, how to incorporate it into a stompbox gain control...
