Blended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement. Shown only within a gear class, and only where there's enough evidence to be meaningful.43% — somewhat different

The MXR Prime Distortion is a classic hard-clipping op-amp distortion pedal from MXR delivering aggressive, harmonically rich distortion suited to rock, blues, and heavy playing. The Prime Distortion uses the hard-clipping op-amp topology that defines MXR's distortion character, providing the bright, cutting, aggressive quality that made MXR distortion designs influential since the 1970s.
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.
