About the WALRUS AUDIO Slö
The Walrus Audio Slö is a multi-texture reverb, perfect for creating lush, modulated, dreamy ambient soundscapes. The toggle switch allows you to select from 3 different reverb modes: Dark (Lower Octave), Rise (Ambient Swell) and Dream (Latching Pad) to create deep modulation with long, washy trails.
A secondary function allow you to switch between different wave shapes for the modulation on the reverb trail.
Slö Modes
Dark
Dark mode adds a lower octave to your reverb trail. Create deep and wide atmospheric sounds and channel nightmarish soundscapes.
The X control sets the level of a -1 octave signal that feeds the reverb.
Rise
Rise mode is an auto-swell reverb which creates beautiful cinematic swells.
The X control sets the amount of time it takes the reverb to swell in after a note is played. Set it lower for shorter rise times and higher for longer rise times.
Dream
Dream mode provides a lush reverb with a latching pad function. Press the Sustain footswitch to latch the signal.
The X control sets the depth of vibrato applied to the reverb trail. Experiment with the X control to add vibrato over the pad. Press the Sustain footswitch again and the pad will decrescendo according to where the decay knob is set.
Slö Wave Shapes
The Walrus Audio Slö also features 3 different wave shapes, accessible by holding down the Bypass footswitch while changing mode.
Sine
Smooth and even pitch with up and down modulation.
Warp
Asymmetric pitch-up modulation similar to a warped record.
Sink
Asymmetric pitch-down modulation for a sinking detune effect.
Slö Momentary Functions
Bypass
When the pedal is powered but off, press and hold the Bypass footswitch to temporarily activate the pedal for a splash of reverb. Releasing the footswitch turns the effect off and fades it out.
Sustain
Press the Sustain footswitch for long, dreamy reverb trails which ramp up to near-infinite until released, and then ramp back down to the value of the Decay setting.
In Dream mode, 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 control.
Trails Mode
The Walrus Audio Slö can run with or without trails. 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. Toggle between modes by holding down the Bypass footswitch for 1 second while applying power to the pedal. Unplug power and repeat to toggle the other mode.
