The Walrus Audio Fundamental Distortion delivers a wide range of saturated tones in a simple, flexible format—ideal for players at any stage. With three distinct distortion modes and intuitive sliders for Gain, Tone, and Volume, this pedal makes it easy to dial in everything from tight, compressed rhythm crunch to raw, dynamic lead tones. Whether you're chasing heavy doom-laden riffs or bright, cutting solos, the Fundamental Distortion offers tonal depth with minimal fuss.

The three-way mode switch gives you instant access to different clipping flavors: Dark for smooth, high-cut warmth with asymmetric clipping; Si for classic, compressed silicon distortion; and LED for punchy, dynamic gain with more openness and headroom. Designed and assembled in Oklahoma, the Fundamental Distortion is built to deliver pro-level tones in a pedalboard-friendly and beginner-friendly design.
