Designed for electric guitars, the Walrus Audio SLÖ Multi Texture Reverb allows you to fashion textural, modulated, and highly-expressive reverbs. It sports three different reverb algorithms: Dark, Rise, and Dream. One adds a lower octave to the signal, a second swells into existence, and a third is a padlike verb with vibrato applied to the reverb decay.

Controls include Decay, Filter, Mix, and Depth knobs. An X knob is also on hand, and its function changes depending on the reverb algorithm. The Reverb algorithm switch selects among the three and also has a secondary function: it allows you to change the wave shapes of the modulation. The Depth knob has a secondary function—it becomes a Rate knob. To access secondary functions, hold the bypass switch while the effect is on, and secondary controls will be enabled. They will be saved to the algorithm until the next time you modify them.

The bypass switch sports a momentary mode. It utilizes true bypass circuitry to preserve the integrity of your signal when the effect is disengaged. A sustain footswitch is also on hand. This control ramps up the reverb trail to the maximum settings, creating a lengthened reverb tail. When you take your foot off the sustain footswitch, it slowly ramps down to the original setting. This switch changes operation from momentary to latching, depending on the reverb mode you've selected. The pedal requires a separately available power supply to operate.

Secondary Functions

To access the secondary functions: with the pedal engaged, hold down the bypass switch and use the toggle to select the desired wave shape, and then turn the depth knob to set the desired rate. The pedal remembers the wave shape and rate settings for the current algorithm until the next time they are modified. The pedal also maintains the algorithm and depth setting when modifying secondary functions.

Trails Mode

The SLÖ can run in 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.

Controls at a Glance

  • DECAY Knob: Adjusts the length of the reverb decay. Go from tight short reverb at full counter-clockwise, to long drawn out texture at full clockwise.
  • FILTER Knob: Controls the tone of the reverb decay. Each algorithm includes a low-pass filter, and the knob controls the filter cutoff frequency. Turn the knob up to open the filter for brighter tones and down to close the filter resulting in a darker tone.
  • MIX Knob: Turn counter-clockwise for increased dry signal, and clockwise for more reverb. The white line marks the 50% position between dry and wet.
  • DEPTH Knob: Controls the amount of modulation applied to the reverb decay. Go from no modulation, to pitch-bending at high settings. Its secondary function is rate, which controls the speed of the modulation applied to the reverb decay.
  • ALGORITHM Switch: The toggle switch selects one of three onboard reverb algorithms. Its secondary functions are modulation waveshapes, and are accessed by holding down bypass while switching the Algorithm toggle.
  • X Knob: The X knob changes jobs depending on which algorithm is selected.
  • BYPASS Footswitch: Turns the effect on and off. It also features smart bypass switching. When the switch is in off position, press and hold to momentarily activate the effect, adding a moment of reverb texture. Releasing the switch turns the effect off, and fades it out.
  • SUSTAIN Footswitch: 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.

Reverb Modes

  • DARK: Add a lower octave to your reverb trail. Create deep and wide atmospheric sounds or nightmarish soundscapes. The X knob sets the level of a -1 octave signal that feeds the reverb. 
  • RISE: Auto-swell reverb for cinematic swells. The 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 pad will decrescendo according to where decay knob is set. X knob sets the depth of vibrato applied to the reverb trail.

Modulation Wave Shapes

  • SINE: Smooth and even pitch up and pitch down modulation. 
  • WARP: Asymmetric pitch up modulation similar to a warped record. 
  • SINK: Asymmetric pitch down modulation for sinking detune, similar to a Bigsby.
