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 Reverb

The Fundamental Reverb provides you with the core sounds of ambient effects. With three reverb algorithms, you can go from ambient hall to an analog spring emulation, as well as a bright plate emulation.

Key Features

  • Three Reverb Algorithms – The slide switch allows you to change between 3 distinct Reverb algorithms:
  • Hall – Emulates the large sounds of an acoustic hall.
  • Spring – Emulates spring reverb commonly found in tube amps.
  • Plate – Emulates a smooth analog plate reverb.
  • Bypass Switch – Turns the effect on and off.
  • Bypass LED – Illuminated when the effect is engaged.
  • Trails Modes – Hold down the stomp switch when applying power to the pedal.

Specifications

  • Decay: Control the amount of wet reverberated signal that is fed back into the signal.
  • Tone: Control the amount of reverb decay time. Left is minimum and right is maximum.
  • Mix:  Control the mix of the effect and the original clean signal. All the way to the left is fully clean, and all the way to the right is fully Reverb.
  • 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.

Reverb

A reverb pedal is like the rich sauce that ties every flavour on the plate into one smooth experience. It adds depth, warmth, and atmosphere — the sonic equivalent of a perfectly reduced glaze that lingers on the tongue. Whether you’re after the subtle ambience of a cosy café (spring or plate reverb) or the grand echoes of a cathedral (hall or shimmer reverb), this is where your tone breathes and expands. A touch of reverb can turn a dry sound into something lush and inviting — but pour on too much, and it’s all you can taste. Used with finesse, it’s the finishing touch that transforms your tone from plain to unforgettable.
