Fundamental Fuzz

The Fundamental Fuzz is a 3-mode aggressive fuzz pedal with a wide tonal range. It can live anywhere in your chain: hit it with your favorite overdrive or push it into another crazy distortion.

  • 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 cuts highs and above center cuts lows.
  • Volume
  • The Volume slider sets the overall output volume of the pedal.
  • Slide Switch
  • The slide switch allows you to change between 3 distinct different flavors of the pedal. Each position has different clipping modes or tone profiles.
