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.35% — somewhat different

The MXR Custom Shop Raijin Drive is a collaboration with Japanese pedal designer Shin Suzuki, reimagining two iconic Japanese stompboxes -- an overdrive and a distortion -- in a single enclosure with more tonal range than either original. A switch flips between the two voices: the overdrive side is smooth, fat and wide open with a rich harmonic bloom, aimed at classic Dumble-style smooth lead tone, while the distortion side is aggressive and harmonically rich with enough gain to get genuinely heavy. Level, Tone and Drive controls keep it simple. It works best pushing an already gritty amp over the edge, where the distortion mode adds real intensity and aggression, though reviewers note it can turn a little fizzy at extreme settings. Named for the Japanese god of thunder and lightning.
The Univox UD-50 Uni-Drive is a late-1960s/early-1970s Japanese-made overdrive and booster built into a large, treadle-style enclosure resembling a volume pedal rather than a standard stompbox. Built around silicon transistors, it produces a warm yet open, harmonically rich overdrive that stays natural and crunchy at lower settings and turns fuzzy and dense when pushed further, functioning as both a clean boost and a gritty overdrive depending on how hard it drives a tube amp's front end into breakup. It was famously used by Jimi Hendrix during Record Plant studio sessions and by Jimmy Page during Led Zeppelin's early tours.
