Walrus Audio ARP-87 / Fathom Limited Edition Combo
ARP-87 / Fathom Limited Edition Combo
Fathom Multi-Function 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.
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.
ARP-87 Multi-Function Delay
The ARP-87 is a compact, feature-rich delay, packed with a large pallet of inspirational delay tones. Featuring four main algorithms, digital, analog, lo-fi, and slap back, the ARP-87 can cover some serious ground in the world of echoes. The Digital algorithm boasts pristine, crystal clear repeats great for rhythmic riffs. The Analog setting works well to add warmth and dimension to chords and lines without getting in the way. The Lo-Fi algorithm, with its adjustable frequency range on the repeats, goes from warm, warped, and murky, to strait AM radio. Finally, the Slap setting makes it easy to dial in a great slap back echo perfect for smoking chicken pickin’ runs. With other features like our smart bypass switching, and momentary knob ramp, the ARP-87 provides endless creative opportunities that are waiting to be explored.
The X knob changes functions depending on which Algorithm you are using. It adjusts a specific parameter in each algorithm. In Digital, Analog, and Slap modes, the knob will control modulation depth. In Lo-fi mode, the knob will control Filter width.
Note that when changing delay types this loads a whole new algorithm and the tempo must be tapped in again.
The ARP-87 can be run in trails or no trails mode. In trails mode, when you turn the pedal off, the delay trails die off naturally. In no trails mode, the delay trails are abruptly cut off when you turn the pedal off. To toggle between either mode, hold down the bypass switch for 1 second while applying power to the pedal. Unplug power and repeat to toggle to the other mode.
When the switch is in off position, press and hold the Bypass Switch to temporarily activate the effect to add a moment of delay texture. Releasing the switch turns the effect off. When the effect is on, press and hold the bypass switch to momentarily ramp the X parameter to maximum. Releasing the switch sets the X parameter back to the knob location.
Press and hold the Tap Switch to temporarily ramp the feedback to maximum. Release to set the feedback back to the knob location.
