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.48% — somewhat different

Citation/mention fame — how often this gear is cited across artist rigs and gear discussion.The Dunlop Blue Hippo Optical Tremolo is a vintage reissue tremolo pedal from Dunlop, recreating the optical tremolo circuit of the classic blue Univox Hi-Flier tremolo from the late 1960s. Optical tremolo circuits use an LDR (light-dependent resistor) for smooth, natural amplitude modulation with the rounded waveform character associated with vintage optical tremolo pedals. The Blue Hippo was a limited-production Dunlop reissue.
The Source Audio Vertigo is a tremolo and vibrato pedal from Source Audio (Boston, Massachusetts), delivering multiple tremolo and vibrato voicings including harmonic, optical, bias, and rotary speaker modes with MIDI control and Neuro app programmability. The Vertigo provides the widest tremolo and vibrato palette from Source Audio for players who need comprehensive modulation with full preset recall.
