Similarity
citedBlended 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.

Description

The Dunlop Uni-Vibe UV-1 is a reissue of the classic Shin-ei Uni-Vibe optical chorus and vibrato effect, famous for its use by Jimi Hendrix at Woodstock and by Robin Trower throughout his recordings. The UV-1 replicates the original four-stage optical phaser with LFO and photocell circuit for the characteristic liquid, watery chorus sweep. Includes expression pedal input for real-time speed control. Controls include Speed, Intensity, and Chorus/Vibrato mode switch.

The Smokin' Amp Co. Tri-Vibe is a boutique-built version of the True Vibrato circuit originally documented by RunoffGroove, a respected source within the DIY pedal-building community. It delivers Uni-Vibe-style swirling modulation with a genuine vibrato mode (pitch modulation) alongside chorus-like textures, offering players a professionally-built alternative to assembling the circuit themselves.
