Walrus Audio Fathom Multi-Function Reverb Pedal

The Fathom Reverb is a multi-function reverb pedal from boutique pedal wizards – Walrus Audio. It’s a must-have for any ambient guitarist as you’re able to achieve brand new reverb tones that you’d struggle to get from any other pedal but also has incredibly useable hall and plate verb sounds too. 

Get Experimental

Ambient and experimental players are catered for with the Lo-Fi and Sonar reverb sounds. 

Sonar reverb is fed with high and low octaves and the ability to blend the octaves with the X Knob for some truly otherworldly tones. Lo-Fi verb gives you a warm, thin AM sound that fattens up the reverb tone and gives you a stunning touch of grit and character to your reverb.

Modulation Toggle

One of the best ways to get your reverb tone to stand out is by adding a touch of modulation – like a chorusing effect – to the reverb in order for it to gain a subtle shimmer. The Fathom has a toggle that allows you to switch between Low, Medium and High modulation. You can also use the ‘sustain’ footswitch to extend your verbs for a dreamy ambient crescendo of tones.

Here’s what Walrus Audio say about the Fathom Reverb 

The Fathom is a feature-rich reverb with 4 different customized reverb algorithms to choose from. Easily go from tasteful, small room reverb to long, modulated trails dripping of ambient goodness. The toggle switch adds options for low, medium and high modulation. Use the dampen knob to fine tune the tone of the reverb’s decay.

The Fathom features 4 different algorithms.

• Hall – Wide, open and vast with decay that ends with high-frequency rolloff. X knob adjusts pre-delay.
• Plate – Full Body reverb with a smooth decay. X knob adjusts pre-delay.
• Lo-fi – Filtered reverb with decay ranging from warm, to thin AM-sounding radio. 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.

Momentary Functions:

When the pedal is in off position, press and hold the Bypass Switch to temporarily activate the effect to add a moment of reverb. Releasing the switch turns the effect off.

Press and hold the Sustain Switch while the pedal is on, to sustain the reverb decay for a dreamy ambient decrescendo.

Trails Mode:

To turn trails mode on or off, unplug the pedal and press and hold down the Bypass Switch for two seconds while plugging the pedal back in.
