JAM Pedals RetroVibe mk.4 Uni-Vibe

The JAM Pedals RetroVibe Mk.4 is a premium Uni-Vibe style modulation pedal that impresses with its lush pulse, vocal shimmer, and unmistakable warmth. Designed as a ground-up evolution of one of the most respected vibe pedals ever made, the Mk.4 delivers classic swirling modulation with expanded control for modern players.

This pedal is 100% analogue, capturing the organic movement and musical feel that vibe effects are famous for. With Chorus and Vibrato modes, plus a dedicated Tap Tempo footswitch with Ramp functionality, you can shift from slow, liquid waves to fast, rotary-like spins with ease.

The RetroVibe Mk.4 is also expandable via a passive 10k expression pedal (not included), allowing real-time control over modulation speed for even more expressive performance.
