Walrus Audio Slö Multi Reverb Settings Guide
The Walrus Audio Slö is a multi-algorithm reverb designed around slow, evolving, and dream-like reverb textures — Bloom, Cloud, and Rise modes each produce distinct atmospheric reverb characters. The Slö is optimized for ambient, shoegaze, and atmospheric applications where long, evolving reverb textures are the primary sonic goal.
The best Walrus Audio Slö Multi Reverb settings start with: Decay at 6/10, Mix at 5/10, Tone at 5/10, Depth at 3/10, Mode at 3/10. Adjust from there based on your amp, guitar, and room volume. For Shoegaze: Decay 8/10, Mix 7/10, Tone 4/10, Depth 5/10, Mode 5/10.

Settings by Genre
Cloud mode with long Decay and high Mix — the Slö in Cloud mode produces a granular, dense reverb texture ideal for shoegaze wall-of-sound. Decay 8 sustains the texture significantly. Tone 4 darkens the reverb tail for the heavy, low-frequency emphasis of shoegaze. Depth 5 adds evolving modulation within the dense cloud.
Rise mode at near-infinite Decay — Rise mode produces a slow-attack reverb swell that builds under each note. Decay 9 extends the swell significantly. At these settings the Slö produces a continuous ambient bed that supports sustained note playing for ambient music.
Bloom mode — the standard long reverb algorithm with moderate Depth for post-rock guitar. Bloom at Decay 7 produces a long, clean reverb that supports the dynamic swells of post-rock without the granular complexity of Cloud mode. Mix 5 keeps the dry signal present for rhythmic definition.
A shorter Decay in Bloom mode adds dimension to jangly rhythm playing without the more extreme, wall-of-sound character the pedal is primarily known for.
Maximum Decay and Mix in Cloud mode pushes the granular processing toward near-total textural transformation, useful for building slowly evolving drones from simple source material.
Tips & Common Mistakes
- The slow-attack swell of Rise mode creates a volume swell effect from sustained notes — attack the string normally but the reverb envelope rises slowly beneath the note. Using Rise mode with a volume pedal placed before this pedal creates a dramatic, orchestral ambient swell with two independent control sources for the overall envelope shape.
- Cloud mode granular processing is a genuinely different algorithm from Bloom, not just a longer decay setting — worth auditioning both specifically rather than assuming Cloud is simply an extreme version of Bloom.
- Depth (modulation) adds movement within the reverb tail itself, distinct from Decay length — a short Decay with high Depth produces a brief but actively shifting texture, while a long Decay with low Depth produces a stable, unchanging wash.
- This pedal favors sustained chords and slow melodic playing over fast picking — the evolving, dream-like textures need time within a note to develop fully.
- For shoegaze and post-rock use specifically, placing this reverb after a fuzz or overdrive rather than before keeps the distortion character intact while the reverb builds the atmospheric layer on top.

Decay: Reverb tail length — at maximum approaches infinite sustain. (Short to Infinite). Mix: Wet/dry blend. (Dry to Wet). Tone: Frequency character of reverb tail. (Dark to Bright). Depth: Modulation depth on the reverb — creates movement within the tail. (None to Full). Mode: Algorithm: Bloom (standard long), Cloud (granular), Rise (slow-attack, swell). (Bloom to Rise)
