Walrus Audio Fundamental Distortion
Walrus Audio · pedal
The Walrus Audio Fundamental Distortion is a streamlined distortion pedal from Walrus Audio's Fundamental Series, using slider controls for Gain, Tone, and Volume alongside a 3-position mode switch (Dark, Si, LED) that fundamentally changes the clipping style and voice, effectively packing three distinct distortion circuits into one compact, pedalboard-friendly enclosure. Dark mode uses asymmetric silicon clipping with a high-frequency cut, Si mode delivers classic compressed, crunchy silicon hard clipping, and LED mode offers a more dynamic, articulate crunch via LED hard-clipping diodes.
