Capacitor value = Frequency cut chart?

[tenser75]

maybe this question makes no sense, but is there somewhere a chart, to understand how the capacitors affects the frequency that get cut from the signal?

ex. if I use a 100nF vs. a 10nF in the input signal of a fuzz, what is the frequency that im cutting off?

does it make sense?

It depends on other parts/values in the circuit.  You can't make the calculation by the cap alone.

Here's a good calculator. Fill in the blanks ... in the equation and your question.

It totally makes sense, but unfortunately there are usually too many other variables that work in conjunction with the cap value to give a definitive, reliable answer.
However, for a rough guide, check out this simple RC filter calculator:

If you want to know the high-pass cut-off for a given input cap value, you would need to know the effective resistance to ground: I think this would be the combined parallel values of any pull down resistor "before" the cap, bias resistor "after" the cap (e.g. if it was an input cap leading to a BJT base,  JFET gate or opamp input with a bias resistor) and also the volume pot value of the guitar that is plugged into the cap.

That is a good calculator. Looks like he has high-pass as well.

Yes....because, the C is also dependent upon the resistance present in the input to the device...and also the input impedance. 

Read up on "capacitive reactance" to understand the 'why', and to get a bit more on 'impedance'...but there are basically 3 legs...capacitance, resistance/impedance, and frequency. 

All things being equal, we often simplify to "F = 1/2piRC".   So if you know 2 properties, you can find the other by rearranging...you COULD chart this for your one fuzz, but it will change with other devices.    Often, the ballpark figure is ok, plus find the freq. for 1 or 2 other cap values, then 'tune it by ear'...bigger = more bass, as you may know.

Reactance Chart.

But first- understand the WHOLE circuit.

Or if it is already built-- leave the resistors alone (they may do DC work), scale the caps 2X larger for an octave lower (and vice versa).
