The Walrus Audio Slötvå Multi Texture Reverb is a reverb pedal that takes the company's popular Slö and adds the ability to create and save three presets123. Released in January 2022, it keeps the Slö's three ambient reverb algorithms, Dark, Rise and Dream, and its control layout, while letting a player store and recall settings from the pedal itself4. Walrus Audio has since discontinued it5.
For a player, the Slötvå is aimed at ambient and soundscape work. Delicious Audio's buying guide describes the Slö family as specializing in "lush, modulated, sleepy and ambient soundscapes" through its three dreamy algorithms6.
An upgrade to the Slö with saveable presets
The Slötvå is a variant of the Slö Multi Texture Reverb, and the difference is in the name of the feature it adds: the ability to create and save three presets123. Guitar.com's launch report notes that the Slötvå features the same controls and layout as the original Slö, with controls for decay, filter, mix and modulation depth, plus an X knob that changes function depending on the selected algorithm4. Premier Guitar's review describes the pedal as derived from the company's very similar Spin FV-1 chip-based Slö reverb10.
MusicRadar sums up the family history plainly: "Then came the Slötvå and it brought presets"11. For a player who found one Slö setting they loved and wanted to keep, or who wanted to move between a subtle room and a huge swell mid-set, the presets were the reason to choose the Slötvå over the original.
The pedal was offered at a retail price of $229 at launch7, and Delicious Audio described it as a limited edition at that price3.
Walrus Audio's product page states the Slötvå is discontinued and no longer available5. A later Guitar.com review says the company discontinued it because of poor sales, calling it a relative flop before the success of the Lüm Texture Engine, which draws on elements of the Slötvå12.
The Dark, Rise and Dream modes
A toggle switch selects three reverb modes: Dark (Lower Octave), Rise (Ambient Swell) and Dream (Latching Pad)13. Premier Guitar's review notes that all three algorithms range to super-long decay times10.
| Mode | What it does | What the X knob does |
|---|---|---|
| Dark | Adds a lower octave to the reverb trail, for deep and wide atmospheric sounds5 | Sets the level of a -1 octave signal feeding the reverb5 |
| Rise | Ambient swell13 | Varies by mode; Guitar World notes the X knob can set the time it takes a note to swell after it's played14 |
| Dream | Lush reverb with a latching pad function5 | Sets the depth of vibrato applied to the reverb trail5 |
In Dark mode, the pedal adds a lower octave to the reverb trail. Guitar World's launch coverage notes that, according to Walrus Audio, Dark accesses the lower octave14. Premier Guitar's reviewer puts it in plainer terms: "Dark" adds a minus-one-octave signal10.
Dream mode is the pad and freeze mode. Press the sustain switch to latch the signal; press it again and the pad decrescendos according to the decay knob setting5. Premier Guitar describes the latch function as effectively "freezing" the reverb signal10. The X knob here controls how deep the vibrato applied to the reverb trail goes5.
Guitar World highlights the X knob as the pedal's most flexible control, noting it can be used in a variety of ways depending on which mode is selected, including setting vibrato levels and swell times14.
Where it sits in the Walrus Audio range
The Slötvå is listed in Walrus Audio's Obsidian Series, the maker's dark-finish pedal range8. Within the company's reverb lineup it sat alongside the original Slö and the stereo Slöer, and its algorithms later fed into the Lüm Texture Engine, which Walrus Audio built from elements of its Fable, Lore and Slötvå pedals12.

Questions
What is the difference between the Walrus Audio Slö and the Slötvå?
The Slötvå is a variant of the Slö with the same controls and layout, and the same three reverb algorithms. What it adds is the ability to create and save three presets, so you can recall different reverb settings without bending down to turn knobs. Premier Guitar also describes it as derived from the Spin FV-1 chip-based Slö.
Has the Walrus Audio Slötvå been discontinued?
Yes. Walrus Audio's product page states the pedal is discontinued and no longer available. A later Guitar.com review says the company discontinued it because of poor sales, describing it as a relative flop before the success of the Lüm Texture Engine, which draws on elements of the Slötvå.
What does the X knob do in Dream mode on the Slötvå?
In Dream mode the X knob sets the depth of vibrato applied to the reverb trail. Dream itself is a lush reverb with a latching pad function: press the sustain switch to latch the signal, press it again and the pad decrescendos according to the decay knob setting. Premier Guitar describes the latch as effectively freezing the reverb signal.
What series is the Slötvå part of?
The Slötvå is listed in Walrus Audio's Obsidian Series, the maker's range of dark-themed pedal finishes. It was released in January 2022 as a variant of the Slö multi-texture reverb, and Delicious Audio also described it at launch as a limited edition.
Does the Slötvå have a lower octave in the reverb trail?
Yes, in Dark mode. Dark adds a lower octave to the reverb trail, and the X knob sets the level of a minus-one-octave signal that feeds the reverb. Walrus Audio describes it as a way to create deep and wide atmospheric sounds. Rise and Dream, the other two modes, do not add the octave.
