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 JAM Pedals RetroVibe mk.2 is a vibrato/chorus pedal emulating the classic Uni-Vibe circuit, built with photocells, a bulb, original NOS 2SC828 transistors, and carbon-comp resistors for period-accurate warmth, housed in a modern, pedalboard-friendly enclosure. It runs on standard 9V DC power internally lifted to 15V DC, drawing 80mA, and represents the original version in JAM's RetroVibe lineage, before the mk.3 added switching and expression-pedal refinements and the mk.4's ground-up control-range redesign.

The Strymon UltraViolet Vintage Vibe faithfully recreates the iconic Uni-Vibe sound in a modern, reliable pedal, delivering vintage chorus and vibrato swirl without the inconsistency of original units. Its algorithm captures the characteristic woosh, swell, and quirks of a real Uni-Vibe, and it is hard to distinguish from analog vibe pedals while being easy to dial in and generally less intrusive. The simple layout has three knobs, Volume, Speed, and Intensity, plus two switches: one selecting modulation type and one adjusting bias. It offers traditional 100% wet Vibrato, a 50/50 Chorus, and a subtler 70/30 Blend for gentle frequency movement. Musical and versatile, it suits players wanting to dress up and layer clean tones with classic vibe textures across psychedelic, blues, and ambient styles.
