The Walrus Audio Fundamental Phaser is a flexible, digital take on the classic phaser effect, offering a range of lush modulation tones in an easy-to-use format. With three selectable modes—Light, Medium, and Heavy—it covers everything from subtle motion to bold, resonant sweeps and experimental textures. Whether you need gentle movement under chords or swirling intensity for solos and soundscapes, the Fundamental Phaser adapts with clarity and depth.

Control is straightforward with three slide knobs: Rate sets the speed of modulation, Feedback adds resonance and complexity, and Depth adjusts the overall intensity of the effect. Built for both beginners and seasoned players, it’s a reliable tool for shaping dynamic, expressive modulation with simplicity and precision. Like the rest of the Fundamental Series, it’s designed and assembled in Oklahoma, USA, with performance and usability in mind.
