Walrus Audio SLÖTVÅ is a variation of the 3-mode SLÖ multi-texture reverb, one of the most popular pedals by the Oklahoma City-based company, which has been regularly on top of our article about the best pedals for ambient and shoegazer music for a while now.
The improvements here are exclusively related to presets, a feature that the company had time to develop in the Mako pedal series, released after the original Slö, which is therefore taken “up to speed” with those three models.
Together with the actual presets, you also get the “spillover” effect when changing them on the fly, which basically gradually fades the settings from one effect to the other, although this only happens when the next preset is the same algorithm as the one preceding it
The rest of the pedal, algorithms included, is identical to the original (you can learn more about that one here), although the SLÖTVÅ also comes in this beautiful custom enclosure inspired by national parks:
Here are the videos of the Walrus Audio SLÖTVÅ.
Walrus Audio SLÖTVÅ, Builder’s Notes
The Slötvå Multi Texture Reverb is a variant of the Slö but adds on the ability to create and save three presets. Save your favorite dreamscapes by simultaneously pressing and holding down on the bypass and sustain switches. Scroll through them by simultaneously pressing and releasing bypass and sustain.
The Slötvå 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 Slötvå.
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.
The Slötvå 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 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 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 Slötvå 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.
When scrolling through presets, there is only preset spillover if the next preset is the same algorithm as the one preceding it. For example, if your red and green presets are both in Dream mode, switching from red to green will not cut your reverb trails.
