Description

Dive into an ocean of sonic possibilities with the Walrus Audio Slö / ARP-87 reverb effects pedal, a true masterpiece for musicians who use reverb as a creative tool rather than just a background effect. This pedal offers three reverb modes—Dark, Rise, and Dream—that allow you to sculpt your soundscapes from lush, modulated waves to cinematic swells and infinite textures. Whether you're looking to add a haunting lower octave, create ambient swells that breathe life into your compositions, or explore the realms of endless reverb pads, the Slö is your gateway to auditory creativity.

The X knob acts as a secret weapon, offering precise control over each mode's unique parameter, whether it’s adjusting the octave in Dark mode, setting the swell time in Rise, or tweaking vibrato depth in Dream mode. And for the adventurous performer, the momentary switching and sustain features let you highlight phrases with bursts of reverb or sustain pads for dramatic effect.

Crafted with top-mounted jacks and a true bypass design, this pedal fits seamlessly into any pedalboard setup. Its trails mode ensures your reverb decays naturally, maintaining the integrity of your core sound.

Key Features:

  • Three distinct reverb modes: Dark (lower octave), Rise (auto-swell), Dream (latching pad)
  • X knob for mode-specific parameter control
  • Three selectable modulation waveforms: Sine, Warp, Sink
  • Momentary switching and sustain footswitch for dynamic reverb control
  • True bypass design with trails mode on/off
  • Power supply via 9V DC (not included)
  • Made in the USA with top-mounted jacks for easy integration

Critic Reviews

Walrus Audio ARP-87 Review - Premier Guitar

premierguitar.com

The Walrus Audio ARP-87 is a versatile digital delay pedal with strengths in its intuitive controls and solid tones, making it an attractive option for tap-tempo enthusiasts. Its lo-fi textures are particularly praised, offering unique sonic landscapes. However, the pedal's "analog" voice could be more colorful, and the lack of a repeat rate knob might deter traditionalists who prefer dialing in times manually. The design's proximity of switches can be cumbersome, and the need to reset tempo when switching voices may disrupt seamless transitions. Despite these quirks, it stands out in a crowded market for its creative flexibility and solid construction.

Walrus Audio ARP-87 review, multi-function delay tested with synths

synthanatomy.com

Walrus Audio's ARP-87 delay pedal impresses with its sleek design and versatile range of delay algorithms that cater well to both guitarists and synth players. The interface is refreshingly intuitive, allowing for easy, menu-free adjustments. Its four delay modes—digital, analog-style, lo-fi, and slapback—offer diverse soundscapes, particularly excelling in warm and characterful tones. However, the mono-only output and absence of MIDI support may deter synth enthusiasts seeking stereo capabilities or precise syncing. While it offers high-quality sound and a pleasing hands-on experience, those craving experimental extremes might find its classic approach limiting. Overall, a solid choice for fans of traditional delay effects with a modern twist.

Review: Walrus Audio ARP-87 Multi-Function Delay

guitar.com

Walrus Audio's ARP-87 Multi-Function Delay is a versatile powerhouse in the delay pedal arena. With its hybrid digital/analog design, it offers a stunning array of delay textures across four main algorithms and a hidden fifth. The control layout, featuring the unique X knob, encourages deep sonic exploration, and the tap tempo and bypass footswitches add functional flair. While the need to retap tempo when changing programs might be a slight inconvenience, the pedal's overall build quality and tonal richness outweigh this minor gripe. From crisp digital echoes to gritty lo-fi repeats, the ARP-87's sound quality is top-notch, making it a valuable tool for any guitarist seeking both classic and experimental delay effects.
