Roll of freq.

How to calculate the roll of frequency of the tone control?

Hi.
Because there's lots of different sorts of tone controls, there's many answers to this.

If it's a simple high or low frequency filter, use fc= 1/(2.pi.R.C) where fc is in Hertz, pi=3.14, R is in ohms and C is in Farads.
fc is the half-power point, or -3 dB, where the frequencies have *just begun* to be reduced (ie the cut is barely audible at the cutoff frequency).

Hope this helps.

There's also lots on the web about tone controls.
