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.

Citation/mention fame — how often this gear is cited across artist rigs and gear discussion.The MXR Distortion Plus is the original MXR distortion pedal, introduced in 1973 and one of the most influential hard-clipping distortion designs in the history of the electric guitar. The circuit uses a single op-amp with hard germanium diode clipping to produce a compressed, warm distortion character with a distinctive midrange voice. The Distortion Plus is strongly associated with Randy Rhoads, who used it with Ozzy Osbourne, and with Slash on early Guns N Roses recordings. It delivers moderate-to-high gain distortion with warm, natural compression and a mid-voiced character that cuts well in classic rock contexts. The design has been extensively copied and remains in production as the M104.
The Keeley Super AT Mod Overdrive is a limited-edition premium modification of a Tube Screamer-style overdrive circuit by Robert Keeley, incorporating signature AT (Andy Timmons) circuit modifications that extend the tonal range and improve harmonic character beyond the stock circuit. The AT modifications address specific Tube Screamer limitations including bass response and clipping character, producing a more natural, harmonically complex overdrive suited to expressive blues and rock lead playing.
