Walrus Audio ARP-87 Multi-Function Delay
The Walrus Audio ARP-87 Multi-Function Delay is a compact pedal in a cool case. It features four main algorithms: Digital, Analog, Low-Fi, and Slap Back. The Digital algorithm is for clean, crystal clear repeats. The Analog setting works well to add warmth and dimension to chords. The Lo-Fi algorithm, with its adjustable frequency range on the repeats, goes from warm, warped, and murky, to straight AM radio. Finally, the Slap setting makes it easy to dial in a great slap back echo. The X control knob adjusts either the modulation depth or the filter width, depending on which algorithm is being used. 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.The pedal also features momentary functions. When the peal is off, you press and hold the Bypass switch to temporarily activate the effect to add a moment of delay until you release the switch. When the effect is on, you 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 and you’ll temporarily ramp the feedback to maximum. Release it and you’ll set the feedback back to the knob location.
