Save your favorite dreamscapes with three onboard presets by simultaneously pressing and holding down on the bypass and sustain switches. Scroll through them by simultaneously pressing and releasing bypass and sustain.
The five-way rotary dial allows five different reverb modes - the three you know and love from the Slö: Dark (Lower Octave), Rise (Ambient Swell), and Dream (Latching Pad); and the addition of two new modes: Rain (Delay Tap Diffusion) and Light (High Octave Shimmer). Secondary functions on the dial change between five different wave shapes for modulation on the reverb trail.
Combine deep modulation, long washy trails, and an immersive stereo field to experience Slöer.
5 Different Modulation Algorithms (Lower Octave, Ambient Swell, Latching Pad, Delay Tap Diffusion, and High Octave Shimmer)
5 Specific Wavelength Functions (Sine, Warp, Square, Pink, and Random)
3 Preset Slots to Save Your Favorite Sounds
2 Different Momentary Functions
“X” and “Stretch” Sliders to Manipulate Reverb Swell
Stereo Width Switch
Die Cast Enclosure
Algorithms:
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: 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 the pad will decrescendo according to where the decay knob is set. X knob sets the depth of vibrato applied to the reverb trail.
Rain: Tappy and trippy, this program creates a unique effect with lower levels of diffusion allowing the reverb delay taps to audible create an echo-like effect within your reverb. Use the Xcontrol to set the amount of diffusion of the delay taps.
Light: Bright and smooth reverb with an octave-up shimmer. Create a range of ethereal sounds with the X slider, keep it low for a smooth pad-like reverb or push it higher for a bright shimmer effect.
Wave Shapes
The Slöer also features five different wave shapes accessible by holding down bypass while switching the algorithm dial.
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.
Square: Symmetric pitch up and down modulation for stepped modulation.
Random: Uses sample and hold that picks new random values.
Momentary Functions:
Bypass: When the switch is in the 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 a 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.
Size of Enclosure: 4.79” x 3.62” x 2.25” including knobs.
Power Requirements: 9VDC (100 mA minimum).
Power Supply: Sold separately (The use of an isolated power supply is recommended for powering all Walrus Audio Pedals. Daisy chain power supplies are not recommended.)

Superb Reverb Effects Pedals for Synths
I recently got an Arturia Minifreak and needed a dedicated reverb pedal to complement it so I decided to get this pedal. It is running into a Soma Cosmos pedal for some out of this world looping effects. I am surprised at the tones I can get out of this pedal with direct, per knob functions for the ...

Beautiful and surprising combinations
I saw this pedal on a Jonathan Nathan Cordy YouTube review, and ordered it immediately. I love shimmer as an idea, but seldom in practice, and when I heard the review I wanted this again. I am not disappointed. I immediately set up a small board, including this with my Hx Stomp and the ability to ta...
