The Walrus Audio Lüm isn’t just another reverb pedal, it’s an invitation to step into entirely new sonic territory. Blending granular processing, ambient textures, and immersive reverb into one inspiring package, Lüm transforms ordinary notes into evolving soundscapes that shimmer, swell, and shift beneath your fingertips. Whether you’re creating cinematic atmospheres, experimental sound design, or lush ambient washes, this limited-edition pedal rewards creativity every time you engage it.

Three distinct processing modes offer dramatically different ways to shape your sound, from fractured grain clouds and spacious granular reverbs to mesmerizing forward and reverse reverb combinations that seem to bend time itself. The innovative Stretch Engine lets you manipulate the character and movement of each effect, while the Moment function adds expressive automation at the touch of a switch, allowing parameters to glide naturally as you perform. With onboard presets, seamless preset transitions, and selectable bypass modes, Lüm is equally at home on a studio desk or the most demanding live pedalboard.

Designed for players who love to experiment without sacrificing musicality, the Lüm delivers inspiring textures that pair beautifully with everything from clean guitars to soaring lead tones and massive walls of gain. It’s the kind of pedal that encourages you to lose track of time while discovering entirely new sounds. Available now at Haggerty’s Music.
