Walrus Audio Slö

Walrus Audio · pedal

The Walrus Audio Slö is a multi-texture ambient reverb built for lush, modulated, sleepy soundscapes, with three distinctive algorithms designed to bring dreamlike textures to life. The Dark mode adds a lower octave to the reverb trail for deep, wide, ominous atmospheres, the Rise mode is an auto-swell reverb that gently fades each note in for beautiful cinematic swells, and the Dream mode is a lush reverb with a latching pad function that sustains the signal when the switch is held. Onboard modulation adds movement and evolving washes, and the controls allow extensive adjustment from smooth, atmospheric decay to huge, washy textures. Each algorithm has its own color and character, and the interface is user-friendly. It is a favorite for shoegaze, ambient, post-rock, and cinematic players wanting evolving, dreamy reverb textures and pad-like sustain in a compact pedal.
