Walrus Audio LUM Texture Engine Reverb Pedal

Limited to 600 units worldwide, the Lüm is a limited edition experiment with elements of the Slö Reverb, Lore Reverse Reverb, and Fable Granular Generator. 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:

• Mode I - Grain Cloud: A grain cloud with dual granular taps reading from a feedback delay line. Experiment with stacking other modulated or wet effects on your board to create all-new sounds. X knob controls the grain size, or how frequently you’ll hear the “glitches” happen.
• 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. X knob controls the grain size, or how frequently you’ll hear the “glitches” happen. Tip - Lüm is a treat to put before high-gain pedals in mode two.
• 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. Use the stretch knob to change how fast or slow this interaction is. X knob controls the reverse reverb decay.

Moment Control - Lüm allows you to automate any one of the five knobs by holding the Moment switch to glide to a defined target, adding dynamic, expressive motion in real time.

Ramp - Holding bypass and adjusting the Mode toggle allows you to adjust the automation glide time between 10ms, 1000ms, and 5000ms.

Stretch Engine - Globally shift the sample rate from 0.5x to 2x speed, stretching time, and interacting uniquely with grain size, reverb decay, and filter tone.

Presets - Save and recall up to three onboard presets (Red, Green, Blue). Sounds fade seamlessly between presets for smooth live transitions.

Bypass Modes - Choose between Trails for natural decay or Instant Cut for abrupt, rhythmic stops.
