Walrus Audio ARP-87 Multi Function Delay - (Used/Excellent Condition)
The ARP-87 is a compact digital delay with four algorithms: digital for clean rhythmic repeats, analog for warmer echoes, lo-fi for filtered and degraded tones, and slap for quick back echoes. The X knob adjusts modulation depth on digital, analog, and slap modes or filter width on lo-fi. It includes tap tempo with four subdivisions, smart bypass switching, and a trails mode that can be toggled by holding the bypass switch during power-up. Momentary functions let you ramp the time or repeats knobs while holding the tap switch. Max delay time is 1000 ms.
