JAM Pedals - Retro Vibe MK.4

The RetroVibe has earned its place among the most celebrated Uni-Vibe interpretations in existence, recognized for its lush pulse, vocal shimmer, and unmistakable analog warmth. The new mk.4 carries this legacy forward with a proprietary all-analog redesign that preserves the soul of the original while significantly expanding its expressive possibilities.
