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.

Specifications

  • 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.

Distortion

Distortion pedals take your clean guitar signal and transform it into something bigger, bolder, and full of attitude. By clipping the waveform, they add sustain, bite, and aggression, creating that thick, compressed tone that’s powered rock music for decades. From the growling crunch of classic hard rock to the tight, saturated roar of modern metal, distortion is all about energy and presence. It gives every note weight and authority, pushing your amp to its limits and beyond.

There are countless flavours of distortion, each with its own texture and edge. Some sound smooth and creamy, others raw and gnarly like tearing fabric. It’s the sonic equivalent of turning up the heat until the sound cooks — rich, sizzling, and perfectly seasoned to taste. Whether used for rhythm muscle or soaring leads, a good distortion pedal doesn’t just add volume; it adds personality, grit, and that unmistakable sense of power under your fingers.

New

This is brand new, fresh in, and a UK warranty is included. New Gear always comes from trusted UK music retailers.

Volume

Volume pedals control the output level of a guitar signal using a foot-operated treadle. They allow smooth volume swells, dynamic control during playing, and easy muting between songs. Volume pedals can be placed at different points in the signal chain to either control overall loudness or adjust gain and drive behaviour when positioned before distortion or overdrive pedals.
