For the Fundamental Series, Walrus Audio have challenged themselves to design a set of pedals with the tonal integrity that’s required to live on a professional’s pedalboard, but with simplified controls friendly enough for even the newest effect pedal users.

Each Fundamental pedal has 3 sliders for tweaking the sound and a three-way switch for changing pedal modes. The result is a line of 8 pedals that will keep you covered from your first band practice, all the way to a sold-out arena.

Fundamental Distortion

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

Key Features

  • Distortion Variety – The slide switch allows you to change between 3 distinct flavours of the pedal. Each position has different clipping modes or tone profiles:
  • Dark - Asymmetric silicon clipping with added high-frequency cut. Think dark and dynamic.
  • Si - Classic silicon hard clipping diodes. Things get compressed and crunchy.
  • LED - LED hard clipping diodes. A dynamic and crunchy sound. The LED clipping mode will be louder due to the nature of the LEDs, so use your volume slider to compensate!
  • Bypass Switch – Turns the effect on and off. 
  • Bypass LED - Illuminated when the effect is engaged.


  • Gain: The Gain slider sets the amount of gain applied to your guitar signal.
  • Tone: The Tone slider controls the frequency response of the signal. Below center boosts highs and above center cuts highs.
  • Volume: The Volume slider sets the overall output volume of the pedal.
  • Input Jack: 1/4-inch cable from the instrument.
  • Output Jack: 1/4-inch cable to amplifier.
  • 9v Jack: 9-volt DC, Center Negative, 100mA min.
