Jam Pedals RetroVibe MK4

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 ground-up all-analog redesign 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. The RetroVibe Mk.4 is already in the hands of Paul Gilbert, Greg Koch, Joey Landreth, and Ruban Nielson of Unknown Mortal Orchestra, long-time RetroVibe users, whose feedback on the Mk.4 has been unanimously enthusiastic. Plug in a standard passive 10k expression pedal for real-time control of modulation Speed, and shape the sound as it moves. Roses are red violets are blue the RetroVibe’s purple and you’ll looove it too!
