JAM Pedals RetroVibe mk.4 Vibe/ Vibrato Pedal

The top-notch Uni-Vibe of the market, upgrated with Tap Tempo

The RetroVibe has long stood among the most revered Uni-Vibe interpretations ever made, celebrated for its lush pulse, vocal shimmer, and unmistakable warmth. The mk.4 continues that legacy. Its all-analog design preserves the soul of the original while expanding its expressive range. A wider Depth and Speed span, plus new Tap Tempo and Ramping functions, invite deeper interaction and performance freedom. Switch between Chorus and Vibrato modes to explore everything from slow, liquid waves to fast, rotary-like spins — always alive, always unmistakably RetroVibe. Plug in a standard passive 10k expression pedal for real-time control of modulation. Speed, and shape the sound as it moves.
