Featuring four modes (Hall, Plate, Lo-Fi and Sonar, which is a reverb with added octaves for that famous “shimmering” effect), this is a stompbox packed with features that can deliver both classic and edgy sounds. The top three knobs tackle decay length, reverb tone and mix, while the “X” knob control a different function for each mode.
Check out the manufacturer’s description at the bottom of the entry and the several video demos below.
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.
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.
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.
