About this listing
Illuminate your soundscape with the Walrus Audio Lüm, a premium granular reverb pedal designed to transform your guitar or synth into a dynamic ambient instrument. Combining three unique granular reverb modes inspired by Slö Reverb, Lore Reverse Reverb, and Fable Granular Generator, Lüm fractures your audio into tiny grains wrapped in lush reverberations, creating immersive, shifting textures.
Main Features
Three Distinct Granular Reverb Modes
Mode I – Grain Cloud: Dual tap feedback delay line produces granular textures with adjustable grain size via the X knob. Ideal for glitchy, ethereal effects.
Mode II – Grain Verb: Granular reverb combining delay memory with a lush reverb tank to create dense, washed-out tones where grains fully immerse in reverb. Great before high-gain pedals.
Mode III – Forward / Reverse Verb: Rhythmic interplay between forward and reverse reverbs. Use the Stretch knob to control speed and X knob to adjust reverse reverb decay.
Moment Control Automation
Hold the Moment switch to smoothly automate any of the five controls, adding expressive real-time motion.
Ramp Control
Adjust automation glide times between 10 ms, 1000 ms, and 5000 ms by combining Bypass with Mode toggle.
Stretch Engine
Globally shift sample rate from 0.5x to 2x to stretch time, affecting grain size, reverb decay, and tone.
Onboard Presets
Save and recall up to three presets with seamless, fade-driven transitions for live performance flexibility.
Bypass Modes
Choose between Trails for natural decay or Instant Cut for immediate, rhythmic stops.
