Product Description

Drift away on a sea of calming tone with the Walrus Audio Slö. This is a shoegazer guitarist’s dream pedal. Dial in textured reverb filled with three algorithms of lush modulation. Create rich soundscapes from the Slö all by itself.


Select your mode of choice; Dark, Rise and Dream, all with unique and evoking sounds. Dark adds a lower octave to your reverb trail, widening the atmosphere you create through the Depth and Mix dials.

Rise is an auto-swell, slowly lifting the effect through the frequencies. The X control knob sets the time it takes to swell after you play a note. Dream is closer to your classic latching pad reverb. Create anthemic waves of sounds with a touch of inbuilt smooth vibrato.


The sustain footswitch works well in Dream mode to ramp up the effect and trail the decay with a stream of pulsing vibrato. Press once again to transition back to your dialled in tone.  

Wave Shapes

Pick one of three wave shapes to take your tone deeper again. Sine is a warbling modulation that adds movement and unpredictability. Warp is an asymmetric pitch up - like an old vinyl - while Sink is a pitch down similar to a Bigsby tremolo to breaking point.


The Slö has an optional trails mode so you can choose whether the reverb slowly dies off naturally or halts completely when you deactivate the effect. As with all Walrus Audio pedals, the Slö is true bypass and won’t adversely affect your tone when switched off.

Sounds ok, but kinda soul-less. It's nice, but doesn't"wow!" me if I'm being honest. My Digitech Supernatural wipes the floor with it. The 'Sustain' function is cool, though.

I ****** love this pedal. Great range of sounds available from subtle reverb to weird and out there soundscapes. Shame they are more expensive but I think they are worth it.

Very nice pedal, capable of everything from subtle reverb to spacey surreal effects. The multi function controls are easy to use after watching a few YouTube tutorials. I've hardly scratched the surface yet but love it.
