The Walrus Audio Fundamental Fuzz is a bold, aggressive fuzz pedal built to deliver raw, ripping tones with simplicity and versatility. Featuring three distinct fuzz modes and a stripped-down control layout, it’s designed to provide massive texture and sustain while remaining accessible to players of all levels. Whether you're stacking it before or after your favorite overdrive or letting it run wild on its own, the Fundamental Fuzz delivers everything from tight fuzz grit to full-blown sonic chaos.

With intuitive sliders for Gain, Tone, and Volume, you can quickly shape your sound and explore a variety of fuzz characters. The three-way mode switch offers different clipping styles, making it easy to shift from saturated vintage-style fuzz to modern, biting distortion. Compact, powerful, and designed for any rig, the Fundamental Fuzz is equally at home in a beginner’s setup or a professional board.
