Gaussmarkov's Dr. Boogey: scaled down tonestack

[Bucksears]

I can see the values scaling DOWN by a factor of 10 for the resistors and pots, but it seems that the cap values go UP by a factor of 10.
i.e. 22nF to 220nF, 3nF to 30nF
Also, the treble cap seems to go down by a factor of 100 (680n to 6n8).

Are these values accurate? Shouldn't everything go down proportionally?

hmm.. the treble cap was 680pF originally , not nF....6n8 is correct....

to scale down a tone control by X is to divide the Resistors by X and multiply the caps by X..
that way you mantain the corner freq of the filters, but lower the impedance.

remember that the corner freq is f=1/2*Pi*R*C (or something similar)...

Cool - good to know as I am going to apply the same methodology to the VoxEXP II I'm building.
