The Jam Retrovibe Mk3 is a two-knob Uni-Vibe recreation featuring original NOS 2SC828 transistors and carbon comp resistors.

Like the vintage unit, it offers both Vibrato and Chorus modes and lets you dial in anything from slow-rate wavy sounds all the way to fast Leslie-speaker effect, which can be controlled via an EXP4 expression pedal.

An internal trim pot affects the maximum intensity of the effect, but also dramatically manipulates the sound of the effect while maintaining its true vintage character.

Mk3 features a soft click footswitch and, unlike previous versions, accepts the most common 10K passive Expression pedals.

We added this list to our article about the Best Uni-Vibe Pedals, here are the videos of it!

These are videos of Mk2

Comprised of photocells, a bulb, original NOS 2SC828 transistors and carbon comp resistors, the RetroVibe mk.2 delivers the majestic sounds of the best Uni-Vibe pedals from back in the day, but housed in a modern pedalboard-friendly enclosure and featuring standard 9V DC operation, internally lifted to 15V DC.

Choose between the Vibrato and Chorus settings and navigate from slow-rate wavy sounds all the way to fast Leslie-speaker effects!

Use it in conjunction with our EXP4 Expression pedal for real-time Speed control!

An added twist! We have incorporated an internal trimmer that affects the maximum intensity of the effect, but also dramatically manipulates the sound of the RetroVibe mk.2, all the while, maintaining the pedal’s true vintage character.

Roses are red violets are blue the RetroVibe’s purple and you’ll looove it too!
