How a Guitar Tone Potentiometer Works?

A common guitar tone control is a low-pass filter. It's made from pickup resistance and tone capacitor capacitance. It's called also a RC filter.

A tone pot in a guitar is used as a variable resistor (only two lugs are used). It's placed after or before the tone cap. The more resistance is on this path, the smaller amount of treble will bleed out to the ground. The diagram shows how it work's in three different knob positions:

Tone Control Mod

This post is about a simple guitar tone control modification, which can make your axe's wiring better for your preferences. It's based on a resistor and a capacitor. The values of these parts can be selected from a quite wide range. It means, that you will have a lot of options to choose from, when you will be making this mod.
