Operation of the F1 can be described in a few words: a potentiometer controls the amount of distortion from "silence" oder "brutal" to "sweet" (although we assume the sweetness is rather hot like one million Scoville.); this parameter also features a CV input. The other potentiometer sets the output volume.
