The RetroVibe mk.4 is an all-analog Uni-Vibe-style modulation pedal with lush pulse, vocal shimmer and unmistakable vintage warmth. Expanded Depth and Speed ranges move from slow liquid waves to fast rotary-like spins, while Chorus and Vibrato modes provide two distinct ways to shape the movement.

Tap tempo makes the rate easy to lock in onstage, and the Ramping function glides from the current speed to a second user-defined rate for dramatic transitions. Connect a standard passive 10 kΩ expression pedal for continuous real-time Speed control. The mk.4 preserves the soul of the original RetroVibe while making it far more expressive in performance.

"SpaceSheep" RetroVibe mk.4 details

Chorus and Vibrato
The toggle selects Chorus for the classic pulsing phase character or Vibrato for pitch-focused movement.

Tap tempo and ramping
Tap the TAP/RAMP footswitch to set modulation speed. Hold it to ramp to a second speed; while holding, adjust Speed to set the destination and Depth to set travel time.

Expression control
A TRS input accepts a standard passive 10 kΩ expression pedal for continuous Speed control. A separate TS input accepts an external tap-tempo switch.

Level and startup
An internal trimmer sets maximum output level. The power-on state can be toggled by inserting power
while holding the ON footswitch.

"The RetroVibe gets all the details right. Great Hendrix/Trower style tones, simple intuitive controls, 9 volt power, good footswitch clearance (so my big foot doesn’t bump the knobs), and awesome paint job!"

"The Retrovibe has all the tone as bigger box versions with a much friendlier footprint, easier to power and a fun paint job!"

JAM pedals began in 2005, when guitarist and sonic explorer Jannis Anastasakis set out to build pedals that didn’t just sound good, they sounded alive. What started as a one-man workshop in Athens has grown into a passionate team of builders, artists, and musicians who still make every pedal by hand, one at a time.
