FUZZ PEDAL 'The Crimson recreates the seventh, and possibly rarest, version of the Big Muff manufactured between 1991/92. It has Volume, Tone and Distort controls, with the latter you control the fuzz. With the ''Mode'' button you activate the ''''JHS Mode'', which will add more gain and mid frequencies. For guitarists with inclinations towards Smashing Pumpkins, Wilco, Sonic Youth, David Gilmour, White Stripes or Dinosaur Jr.'
