Walrus Audio ARP-87 Multi-Function Delay Pedal
A compact, feature-rich delay with four distinct algorithms — Digital, Analog, Lo-Fi, and Slap — built for players who want one box that covers nearly every echo on their wish list.
A Smart Fit For You
The ARP-87 is the kind of delay that earns its real estate twice over. If you've been bouncing between a clean digital delay for rhythmic parts, a warmer analog flavor for chords and ambient swells, and a slapback for clean tones, this pedal puts all of them under one footswitch — plus a Lo-Fi mode that takes things from warped tape to AM-radio crunch. The X knob changes its job depending on the algorithm, adding modulation depth in the Digital, Analog, and Slap modes and shaping the filter width in Lo-Fi, so a small twist takes you somewhere genuinely new. Tap tempo, momentary feedback ramp, and trails or no-trails switching round it out into a working musician's delay that thinks like a pedalboard centerpiece.
Key Highlights
- Four delay algorithms: Digital, Analog, Lo-Fi, and Slap
- Up to 1000 ms of delay time
- Tap tempo footswitch with selectable Delay Ratio for subdivisions
- X knob adjusts modulation depth in Digital, Analog, and Slap modes
- X knob shapes filter width in Lo-Fi for warped, murky textures
- Trails and no-trails bypass modes for natural fades or instant cutoff
- Momentary bypass for on-the-fly delay texture without re-engaging the pedal
- Momentary feedback ramp via the tap switch for runaway repeats and self-oscillation
- Frosted Charcoal finish with original artwork by Chris Castro
- Compact pedalboard-friendly enclosure
Why You'll Love It
Features
Six knobs — Level, Dampen, Repeats, Delay Ratio, X, and Program — give you direct hands-on control over every algorithm. Tap tempo, trails switching, and dual momentary functions on the bypass and tap switches add real performance flexibility.
Advantages
Four algorithms in one pedal means fewer compromises on your board. Digital nails pristine grid-locked repeats, Analog adds warmth without mud, Lo-Fi covers tape-style and radio-warped sounds, and Slap delivers tight rockabilly and country echoes.
Benefits
You spend less time hunting between pedals and more time playing. Holding the bypass switch sneaks in a delay texture, holding tap pushes feedback into chaos, and trails mode keeps your ambient tails alive when you turn it off mid-passage.
Great Fit For
- Players who want one delay that covers digital, analog, lo-fi, and slapback
- Worship and ambient guitarists who rely on trails and momentary builds
- Country and rockabilly players chasing tight, musical slapback echoes
- Indie, post-rock, and shoegaze players who lean on warped and modulated repeats
- Pedalboard builders looking to consolidate two or three delays into one box
- Studio and home recording players who need flexible delay textures on demand
Sound and Feel
Each ARP-87 algorithm has its own personality. Digital mode delivers crystal-clear repeats that stay out of the way for rhythmic playing and dotted-eighth lines. Analog adds bucket-brigade-style warmth that sits beautifully under chords and single-note lines without smearing the dry signal. Lo-Fi is where the pedal really stretches its legs, going from gently warped and dusty to full-on AM radio character with the X knob shaping the filter. Slap mode is dialed-in for the moment — short, snappy echoes perfect for chicken pickin', country leads, and rockabilly grooves. Hold the tap switch and the feedback ramps into glorious self-oscillation, then release and it settles right back where you left it.
Specifications
The ARP-87 is one of those rare delays that genuinely earns the "multi-function" name — most players who pick one up end up retiring two or three other delay pedals. If you want to talk through which algorithm fits your style, where it should live in your signal chain, or how it pairs with reverb, give us a shout.
