From the vendor

The Big Muff has always been wonderfully versatile pedal that offers many flavours of fuzz and distortion partly due to the wide-ranging tone knob, which will go all the way from a rounded flutey tone ideal for David Gilmour or Ernie Isley leads, through all the grunge and alt-rock tones, to a brighter, raucous garage fuzz.
