JAM Pedals RetroVibe Mk.4
Jam Pedals · pedal
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.
