This guitar wiring modification shows how to use a small value capacitor 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 the 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. Typical capacitor values are between .001mFd and .003mFd. A larger value capacitor will allow a wider range a frequencies to bypass the volume control and a smaller value capacitor will reduce the range of frequencies that will bypass the volume control. Typical resistor values are from 1M-2M. 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.
