Similarity
citedBlended 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.

Description

The MXR M104 Distortion+ is a classic, simple distortion pedal first introduced in the 1970s, famous for its warm, slightly fuzzy hard clipping distortion and just two controls, Output and Distortion. It produces a smooth, compressed, vintage distortion that ranges from gritty overdrive at lower settings to a singing, saturated lead tone when cranked. Closely associated with players like Randy Rhoads and Dave Murray, it helped define late 1970s and early 1980s hard rock and metal lead tones. Its straightforward, mid friendly voice and easy sustain make it a go to for classic rock, hard rock and players who want a no frills, characterful vintage distortion that pushes an amp into singing leads.

The Walrus Audio Iron Horse is a premium RAT-style distortion pedal from Walrus Audio of Oklahoma City, Oklahoma, based on the classic Pro Co RAT distortion circuit and delivering rich, harmonically complex distortion with the gritty, aggressive character that made the original RAT a classic, in Walrus Audio's premium build quality.
