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.46% — somewhat different

Citation/mention fame — how often this gear is cited across artist rigs and gear discussion.The DigiTech IPS-33B Super Harmony Machine is a rack-mounted intelligent pitch-shifting harmonizer, generating musically correct harmony lines above or below the input signal by tracking the key rather than applying a fixed, mechanical interval. That intelligence made it possible to add real-time two- and three-part harmonies to a single guitar line without the dissonant clashes a simple pitch shifter produces outside the right key. Joe Satriani, known for layering harmonised lead lines in his instrumental work, is associated with this unit.
The Eventide H910 Harmonizer, released in 1975, was the first commercially available digital pitch shifter, letting engineers and players alter pitch in real time without changing playback speed, a capability that had previously required tape manipulation. It became a studio fixture through the late 1970s and 80s for doubling and pitch-shifted effects on vocals and guitars alike. Eddie Van Halen has been associated with early digital effects units of this kind as part of his exploration of studio processing beyond conventional guitar pedals.
