Walrus Audio Lüm Texture Engine - Black

The Walrus Audio Lüm is a unique reverb that manipulates sound in a way you rarely encounter. 

Lüm is a creative experiment that combines elements of the Slö Reverb, Lore Reverse Reverb, and Fable Granular Generator. The result? A pedal that transforms your sound into dreamy, gliding textures full of movement and character across three unique modes. Perfect for ambient music, soundscapes, or simply when you’re looking for something different from standard reverb.

3 experimental modes:

• Mode I – Grain Cloud
  Two granular taps from a feedback delay line create a shimmering cloud of glitches and repetitions. Especially cool when combined with other effects on your pedalboard. Use the X knob to adjust the grain size—that is, how often you hear those characteristic glitchy moments.
• Mode II – Grain Verb
  Think of a classic reverb, but viewed through a granular lens. Two taps draw their input from a reverb algorithm and produce grains that sound as if they’re floating in an ambient bath. Here, too, the X knob determines how often and how intensely the glitchy texture comes through.
• Mode III – Forward Reverse Verb
  A unique blend of forward and reverse reverb. They interact rhythmically, creating a playful, almost pulsating character. The Stretch knob controls how quickly that interaction occurs. The X knob sets the decay of the reverse reverb.

Extra features that make a difference:

• Expressive automation: Hold down the Moment footswitch to temporarily set one of the five knobs to move automatically. Ideal for live expression. Use the Mode toggle to set the glide time: 10 ms, 1000 ms, or 5000 ms.

• Sample rate shifter: Globally slow down or speed up your sound (from 0.5x to 2x), which affects everything—from grain size to tone and decay.

• Presets & smooth transitions: Save up to three presets (Red, Green, Blue) and switch between them seamlessly. Handy for live use.

• Bypass options: Choose between Trails (natural decay) or Instant Cut (immediate stop)—depending on your playing style.

• Power: Runs on a standard 9V power supply (not included), with a current draw of approximately 100 mA.
