    I built a 5mhz freq circuit, to install as a tone control in my guitar.
    I want to know if the 5 mhz isenough to effect the 20-60mhz audio taper or not?
    How does this work? Does the 5mhz just inc or dec the existing, or is it an add to the top, or drop off the bottom or what?
    I would think that a 20mhz would bend from 20 to 25 and a 60mhz would bend from 55 to 65 ??!!?

    5mHz is an incredible low frequency for any audio system. 30Hz to 10kHz is the normal range.

    Show us a schematic of what you have with component values.

    You can simulate the circuit with LTspice to see the effect.

    A tone control circuit usually boosts and cuts bass and treble frequencies. Some tone controls have a mid frequencies boost and cut.

    Nothing "bends", instead the tone controls have a frequency where they begin boosting or cutting and for bass and treble tone controls this frequency is usually 600Hz to 1kHz.

    Here is a schematic and the frequency response of a standard bass and treble tone controls circuit with the bass and treble controls turned to minimum and maximum:
