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.

The Ibanez CS9 Stereo Chorus is a vintage-voiced analog chorus, a reissue of the early-80s CS9, known for a warm, lush modulation. John Scofield runs one with both controls cranked to get a Leslie-like rotary effect. It offers rich, watery chorus from subtle shimmer to deep swirl, suited to clean and lightly driven jazz, fusion and rock tones.
The JAM Pedals RetroVibe Mk.4 is a hand-built uni-vibe widely regarded as one of the finest modern interpretations of the classic effect. It recreates the original sound-generation method of four photocells surrounding a pulsating light source, producing a lush, vocal, wavering swirl with the elusive complex midrange that responds beautifully to pick attack. A switch selects between Vibrato and Chorus voicings, covering everything from slow liquid throb to fast Leslie-style rotary effects, while an internal trimmer reshapes the maximum intensity and character. Used by players such as J Mascis, Andy Timmons, Ruban Nielson and Greg Koch, it suits psychedelic, classic-rock and ambient textures and is considered a gold-standard authentic sixties-style vibe.
