Walrus Audio ARP-87

Overview and Build Quality

The Walrus Audio ARP-87 is a compact digital delay pedal offering a rich set of features in a modest enclosure. At 121 x 66 x 41 mm and weighing just 0.36 kg, it fits comfortably on pedalboards of any size, aided by the top-mounted input, output, and power jacks. The ARP-87's aluminum chassis feels solid, and the build quality earns high marks for durability, with sturdy switches and metal control knobs. Some users mention occasional minor issues with the foot switches, but overall, the construction is robust and reliable for live gigs and regular transport.

Modes and Sound Quality

This pedal stands out by providing four distinct delay voices: modern digital, analog-style, lo-fi, and slapback. Each brings a different character:

• Digital: Clear, precise repeats, retaining note definition even at higher feedback settings. Despite being digital, the sound maintains warmth and musicality, not veering into cold or sterile territory.
• Analog-Style: Modeled to emulate vintage analog delay, this mode produces darker, warmer echoes that blend smoothly into the background. The coloration is well-designed, adding texture without muddiness, and makes for organic, immersive soundscapes.
• Lo-Fi: This setting intentionally degrades the repeats, introducing a tape-like, atmospheric degradation that's ideal for ambient, experimental, or shoegaze-influenced music. The X control (modulation) changes how aggressive or subtle the lo-fi artifacts are, making this mode highly expressive.
• Slapback: Fast, short repeats perfect for rockabilly, surf, country, or quick rhythmic echoes. While simple in approach, it provides punch and immediacy for those genres.

Across all modes, the ARP-87 avoids tone loss or unwanted coloration of the dry signal. Using the Level (blend) knob, the effect is mixed in parallel, so the original instrument remains clear and intact. There's no bypass tonal shift, no added noise, and signal integrity is maintained.

Controls and Functional Design

The ARP-87 forgoes a traditional delay time knob in favor of a tap-tempo foot switch, paired with a rotary selector for rhythmic subdivision (quarter notes, dotted eighth, eighth notes, and eighth note triplets). This approach streamlines tempo matching when playing live, although some users accustomed to manual time settings may find the absence of a dedicated time knob inconvenient.

Other controls are intuitive:

• Repeats: Sets the number of echoes. The range is practical; it doesn't self-oscillate as easily as some analog delays, so wild runaway feedback isn't its specialty, but musical, controlled repeats are easily dialed in.
• Level: Blends the repeated signal with the original.
• Dampen: A tone filter shaping the brightness of repeats (and a frequency filter in lo-fi mode), useful for placing the delay in front or behind your core tone in the mix.
• X (Modulation): Modifies the character and depth of pitch modulation or tape wobble, depending on the selected mode. At extreme settings, lush warbles and seasick movement are possible, especially in analog and lo-fi modes.

Parameter changes are smooth, and the pedal responds musically without harsh digital jumps or artifacts. The interface is packed but not unintuitive, with clear labeling and soft switches that are quiet and comfortable for live use.

Extra Features: Trails, Momentary, and External Tap

The ARP-87 provides a true bypass and a trails switching mode. In trails mode, when the pedal is disengaged, delay repeats decay naturally, preserving a seamless live performance. This feature is toggled by holding the bypass switch during power-up.

Both foot switches double as momentary controls. Holding the effect switch cranks the modulation to maximum or ramps up repeats, depending on state, useful for live dynamic shifts, creating infinite-sustain textures, or sudden atmospheric swells. The tap switch can also be assigned for infinite repeats. An external tap input is provided for those integrating with complex pedalboards or needing extra flexibility.

Use in Practice and On Stage

The ARP-87's sound is described as inspiring and versatile, appropriate for anything from subtle enhancement to more experimental or ambient work. It handles both guitar and synth sources well, and the note clarity under stacked distortion or in complex band mixes is consistently praised. The pedal's focus on musical integration, never overpowering, never sterile, makes it ideally suited for both modern and classic delay applications.

On small pedalboards, its size is a significant advantage. The lack of stereo output is a limitation for those with extensive setups, but for mono rigs, it presents no compromises in sonic performance. Users note the absence of presets or MIDI as minor drawbacks, but for most, the hands-on, analog-style workflow is part of its appeal. The artwork, LED visibility, and small bag/accessories are appreciated details, showing Walrus Audio's attention to presentation.

Conclusion

At a price of $195, the Walrus Audio ARP-87 delivers outstanding value for players wanting comprehensive delay functionality in a small format. With strong build quality, no-compromise audio, four useful delay engines, tap tempo with flexible subdivisions, and intelligent live-oriented features, it holds its own against larger, more expensive units. The lack of a traditional time knob and some occasional ergonomic quirks are the main tradeoffs. For musicians valuing distinctive delay textures with intuitive real-time control, the ARP-87 earns a clear recommendation.
