Fathom

The Fathom by Walrus Audio is a feature-rich reverb pedal with versatile functionality and specific technical specifications. The pedal is housed in a diecast enclosure measuring 4.77" x 2.6" x 1.39" and requires a power supply of 9VDC with a minimum of 100mA. It is recommended to use an isolated power supply for optimal performance.

Key features and functionality of the Fathom include:
- Four different customized reverb algorithms: Hall, Plate, Lo-fi, and Sonar
- Toggle switch for low, medium, and high modulation options
- Dampen knob for fine-tuning the tone of the reverb's decay
- Momentary functions: Press and hold the Bypass Switch to temporarily activate the effect, and press and hold the Sustain Switch while the pedal is on to sustain the reverb decay for a dreamy ambient decrescendo
- Trails Mode: Ability to turn trails mode on or off by unplugging the pedal and pressing and holding down the Bypass Switch for two seconds while plugging the pedal back in

The specific algorithms offer distinct reverb characteristics:
- Hall: Wide, open, and vast with decay that ends with high-frequency rolloff. The X knob adjusts pre-delay.
- Plate: Full-body reverb with a smooth decay. The X knob adjusts pre-delay.
- Lo-fi: Filtered reverb with decay ranging from warm to thin AM-sounding radio. The X knob adjusts filter width.
- Sonar: Reverb fed with both a high and low octave with the ability to blend the octaves with the X knob.

The Fathom also features a momentary function and trails mode for added versatility in creating ambient and atmospheric sounds.

The Luna Series edition offers a limited edition enclosure for a unique visual appeal.
