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.34% — somewhat different

The Catalinbread CATDLSR is a version of the Portland boutique builder's Dirty Little Secret Marshall-voiced foundation overdrive circuit. The DLS models the tone and response of a cranked British Marshall amplifier, delivering classic rock overdrive with dynamic, amp-like feel. Controls include drive, volume, and a three-band tone stack based on Marshall amplifier EQ alongside a mode switch for Super Lead and Super Bass voicings. Used by blues and classic rock players seeking authentic British overdrive character from a compact pedal.
The MXR M77 Custom Modified Badass OD is an overdrive pedal from MXR by Jim Dunlop, a modernized version of the classic MXR circuit designed to deliver touch-sensitive, dynamic overdrive at a wide range of gain settings. The M77 is built around a warm, musical saturation character inspired by vintage MXR designs, with added EQ controls that extend the tonal palette beyond the original stripped-down format. It delivers compressed, warm overdrive suited to blues, classic rock, and hard rock applications and has been used by players who want a rugged, road-ready overdrive with recognizable MXR tone character.
