Walrus Audio's ARP-87 is a sonically expansive delay pedal for dialing in effortlessly musical echoes. The ARP-87 features four delay programs that can be rolled through for quick and subtle slapbacks to deeply off-kilter repeats. Familiar Digital and Analog delays modes are accompanied with the more experimental Lo-Fi and Slap modes. Dig in further with tap tempo functions, four division ratio options, and smart bypass switching. This pedal is best run with an isolated power supply – daisy-chain power supplies not advised. As both a tool for adding smooth space trails to riffs and for delving into a more adventurous delay experience, ARP-87 touches down perfectly.
