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 MXR Phase 90 is one of the most iconic phaser pedals ever made, a single-knob, four-stage analog phaser known for its warm, organic, liquid sweep. With just a Speed control, it is effortless to use, producing everything from a slow, gentle swirl to a fast, watery throb that animates both rhythm and lead playing. Its rich, musical phasing has appeared on countless recordings across classic rock, funk, and beyond, and it is famously associated with Eddie Van Halen's early tone. The compact orange enclosure and simple operation make it a pedalboard staple. It sits early in the chain into clean or driven amps, adding three-dimensional movement without thinning the core guitar tone.
