Can anybody give me some information on designing active tone controls like the one form BOSS overdrive or tube screamer? I'm familiar with MFB and Salien Key filter and Cheybyshev designs but I don't know how to make them adjustable. The tone controls on pedal effect don't seem to be any of these type.
