The Fundamental Distortion is a 3-mode distortion. It covers a wide range of sounds from dark and doom through sharp cutting leads.



  • Gain
  • The Gain slider sets the amount of gain applied to your guitar signal passing through the fuzz circuit.
  • Tone
  • The Tone slider controls the frequency response of the signal after distortion. Below center boosts highs and above center cuts highs.
  • Volume
  • The Volume slider sets the overall output volume of the pedal.
  • Slide Switch
  • The slide switch allows you to change between 3 distinct flavors of the pedal. Each position has different clipping modes or tone profiles.

  • (Slide Switch) Si
  • Classic silicon hard clipping diodes. Things get compressed and crunchy.
