Tap tempo is king in a multi-voiced digital delay with creative echo-shaping controls.

Delay has evolved so much and become so functionally varied that whole user factions with independent value systems now exist. There’s the slapback set, the ambient adventurers, analog adherents that like it dirty, and digital surgeons that prize pristine clean sounds. With a raft of modulation textures, filters, and colors ranging from filthy to squeaky clean, Walrus’ ARP-87 addresses the needs of many of these groups. But it seems especially geared toward a unique breed of delay user known as the tap-tempo control freak—so much so that the pedal disposes of a time knob entirely and relies exclusively on a tap tempo switch and a subdivision knob to determine repeat rates.

The ARP-87’s 6-knob array isn’t crazily unconventional, but it may throw trad-minded, 3-knob analog delay fans a curveball or two if they dive right in without referencing the manual. Apart from level and repeats, and perhaps the ratio knob, which enables selection of subdivisions, the individual controls declare their intent rather obliquely. They are, however, pretty easy to figure out on the fly. Dampen is a tone control, which is useful for taking the sheen off the digital delay or brightening the “analog” voice. X increases modulation intensity in slapback, analog, and digital modes, and adjusts filter width in lo-fi mode. Program enables switching between those four algorithms. The switches themselves have no detents, which can make adjustments tricky in the dark. Here again, though, the options are manageable enough in number to sort in the heat of performance.
