Specifications
This guitar wiring modification shows how to use a small value capacitor (typically around .001 MFD) and high value resistor (typically 500K to 1.5MEG ohms) to add a tuned treble bleed or high frequency bypass feature. This mod will help retain the high frequencies that are lost when volume setting is reduced. In this version of the mod, a resistor is added in parallel with the capacitor. By adding the resistor in parallel, a small amount of ALL frequencies are allowed to bypass the volume pot along with the high frequencies that bled through the capacitor. This is done to prevent the tone from becoming too thin in reduced volume settings and augment the tape of the pot. Larger value resistors will have less of an effect on the tone and taper of the pot. A higher resistor value will thicken up the tone at reduced volume settings, but will also have a greater effect on the volume pot taper. In the variable resistor version of this circuit, a second "limiting resistor is added to prevent the resistance to be set to zero which would short out the capacitor and eliminate it from the circuit. Typical values for the limiting resistor are 500K ohms and higher.
