Walrus Audio ARP-87 Multi-Function Delay Obsidian Series Effects Pedal Black

The Walrus Audio ARP-87 pedal is a compact, feature-rich delay packed with a large pallet of inspirational 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 straight 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 smart bypass switching and momentary knob ramp, the ARP-87 provides endless creative opportunities that are waiting to be explored.

Trails Mode

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 one second while applying power to the pedal. Unplug power and repeat to toggle to the other mode.

Momentary Functions

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.
