Fathom Multi-Function Reverb

The Walrus Fathom is a reverb pedal that offers a treasure trove of atmospheric possibilities. With four customized reverb algorithms at your fingertips, you can effortlessly transition from intimate, small-room reverbs to expansive, modulated soundscapes that ooze ambient goodness. The Fathom also features a toggle switch for low, medium, and high modulation options, allowing you to add depth and dimension to your reverb trails. Fine-tune your reverb's decay tone using the dampen knob for the perfect ambient texture.

Four Distinct Reverb Algorithms to Explore

The Fathom's versatility shines through its four unique algorithms:

  • Hall: Experience wide, open spaces with a vast decay that gradually rolls off high frequencies. Adjust the pre-delay with the X knob for added versatility.
  • Plate: Revel in full-bodied reverb with a smooth decay. The X knob controls pre-delay, allowing you to tailor your sound to perfection.
  • Lo-fi: Explore filtered reverb that ranges from warm and lush to the nostalgic sound of a vintage AM radio. The X knob adjusts the filter width, providing a broad tonal spectrum.
  • Sonar: Immerse yourself in reverb fed with both high and low octaves, and blend them seamlessly with the X knob to create unique sonic textures.

Expressive Momentary Functions and Trails Mode

The Fathom offers creative control with momentary functions:

  • In the off position, press and hold the Bypass Switch to temporarily activate the effect for a burst of reverb. Release the switch to turn the effect off.
  • While the pedal is on, hold down the Sustain Switch to sustain the reverb decay, crafting dreamy ambient soundscapes. Trails Mode is also available, allowing you to decide whether the reverb trails continue after bypassing the effect.
