USED Walrus Audio Slö Multi Texture Reverb Pedal no box included

This is an excellent condition used pedal with a little velcro on the back, but no box.

The idea of reverb in a stomp box is not new but now more than ever folks are yearning to go further than the Spring, Plate and Hall reproductions that have long dominated the game. Guitar tones are evolving with the landscape of music production, and we think a lot of that has to do with atmosphere and feeling surrounding your note and core tone. Enter the Slö Reverb: A glorious box of ambiance that can give your instrument the imposing appearance of a planet or the elegant shimmer of a distant star through a powerful sonic telescope. The three modes of reverb on the Slö are unique, including a sub octave Dark setting, a moving auto swell Rise and a three-dimensional, pad-like Dream mode. However, these are really jumping off points, meant to be thoroughly explored with optional wave shapes and filter controls. The wave shapes are a special tool that allows you to apply pitch modulation up, down or both in any of your preferred reverb mode....a full permutation of sonic possibilities. The momentary switching is a game changer, especially on a reverb pedal such as this. The soft switching system allows you to trigger your reverb for a just a moment, a phrase or more and the second you want it to fade you simply release the switch. This pedal was an eye-opener for us and our old school leanings, proving that even something as "black and white" as reverb can be used as a meaningful tool of expression without getting in the way of your playing style.

In the words of Walrus Audio:

The Slö Multi Texture Reverb allows players to create lush, modulated, sleepy and ambient soundscapes. Stocked with three different algorithms specifically designed to invoke textures for bringing dreams from your subconscious to reality.

The toggle switch allows three different reverb modes, Dark (Lower Octave), Rise (Ambient Swell) and Dream (Latching Pad), while secondary functions on the switch change between different wave shapes for the modulation on the reverb trail.

Combine deep modulation with long washy trails and experience, the Slö.


DARK – Add a lower octave to your reverb trail. Here you'll create deep and wide atmospheric sounds and channel nightmarish soundscapes. X knob sets the level of a -1 octave signal that feeds the reverb.

RISE – This is an auto-swell reverb for beautiful cinematic swells. Don't rush it. Let it breathe and gently wake up. X knob sets the amount of time it takes the reverb to swell in after a note is played. Set lower for shorter rise times and higher for longer rise times.

DREAM – Here is a lush reverb with a latching pad function. Press the sustain switch to latch signal. Experiment with the X knob to add vibrato over the pad. Press sustain again and pad will decrescendo according to where decay knob is set. X knob sets the depth of vibrato applied to the reverb trail.

The Slö also features 3 different wave shapes accessible by holding down bypass while switching the algorithm toggle.

SINE – Smooth and even pitch up and down modulation.

WARP – Asymmetric pitch up modulation similar to a warped record.

SINK – Asymmetric pitch down modulation for sinking detune similar to a Bigsby.


Bypass: When the switch is in off position, press and hold to temporarily activate the effect to add a moment of reverb texture. Releasing the switch turns the effect off, and fades it out. 

Sustain: When pressed, the decay switch ramps up the reverb trail to maximum creating long dreamy reverb trail and then ramps back down to the decay knob setting when released. In the “Dream” algorithm, the sustain switch is latching. Press it once to capture and sustain the current reverb decay for extremely long pad-like sounds. Press it again to let the reverb trail taper off, based on the position of the decay knob.


The Slö can run in trails or no trails mode. In trails mode, when you turn the pedal off, the reverb decay dies off naturally. In no trails mode, the decay is abruptly cut off when you turn the pedal off. To toggle between either mode, hold down the bypass switch for 1 second while applying power to the pedal. Unplug power and repeat to toggle to the other mode.
