    Multi-Function Reverb


    About the WALRUS AUDIO Fathom

    The Walrus Audio Fathom is a multi-function reverb with 4 reverb modes: go from small room reverb to long, modulated trails dripping in ambient goodness.

    Fathom Controls

    The Mod toggle switch allows you to choose either a low, medium or high level of modulation.

    Use the Dampen knob to fine-tune the tone of the reverb's decay.

    Fathom Modes


    A wide, open reverb with vast decay that ends with high-frequency roll-off. The X control adjusts pre-delay.


    A rich, full reverb with a smooth decay. The X control adjusts pre-delay.


    A filtered reverb with decay ranging from warm to AM radio. The X control adjusts filter width.


    Reverb fed with both a high and low octave with the ability to blend the octaves with the X knob.

    Momentary Functions


    When the pedal is powered but off, press and hold the Bypass footswitch to temporarily activate the pedal for a splash of reverb. Releasing the footswitch turns the effect off and fades it out.


    Press and hold the Sustain footswitch for a dreamy, ambient decrescendo.

    Trails Mode

    The Walrus Audio Fathoms can run with or without trails. In Trails mode, when you turn the pedal off the reverb decay dies off naturally. In No Trails mode, the decay is abruptly cut off when you turn the pedal off. Toggle between modes by holding down the Bypass footswitch for 2 seconds while applying power to the pedal. Unplug power and repeat to toggle the other mode.
