Walrus Audio unveils LÜM: A limited-edition granular & textural reverb pedal

Lüm seeks to illuminate your path with three unique granular and textural reverb modes, momentary automation, and presets.

Lüm transforms your instrument with three unique modes into lush, shifting textures that scatter and reassemble your signal, creating immersive backdrops that move and shift with every note to blur the line between instrument and ambient sound design:

Need to know for retailers:  

  • Limited to 600 units worldwide, the Lüm is a limited edition texture experiment.
  • Features elements of the Slö Reverb, Lore Reverse Reverb, and Fable Granular Generator with 3 user presets.
  • Lüm transforms your instrument with 3 unique modes that blur the line between instrument and ambient sound design:
    • Mode I - Grain Cloud: A grain cloud with dual granular taps reading from a feedback delay line.
    • Mode II - Grain Verb: A grain verb with dual granular taps reading from the delay memory of a reverb algorithm tank, which sounds like the grains took a bath in reverb.
    • Mode III - Forward Reverse Verb: A forward reverb algorithm running into a reverse reverb algorithm. You’ll hear a playful rhythmic interaction between the forward and reverse reverbs.
