JAM Pedals Retro Vibe MKII UniVibe


The RetroVibe mk.2 is JAM Pedal’s take on the greatest Uni-Vibe pedal ever made !

The original goal was to achieve the sound of a vintage Uni-Vibe, but after getting there, we looked into taking things a few extra steps further !

Comprised of 4 photocells, a bulb, original NOS 2SC828 transistors and carbon comp resistors, the RetroVibe is an extremely inviting modulation machine, that will immerse you in rich Uni-Vibe textures!

Choose between the Vibrato and Chorus settings and navigate from slow-rate wavy sounds all the way to fast Leslie-speaker effects by setting the speed post 9 o’clock!
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, all the while, maintaining the pedal’s true vintage character.

Hendrix / Trower / Floyd fans, rejoice! This is IT!

*Be advised that the expression input only works with same spec expression pedals as our EXP4 which is sold separately.

*If you have an older version of the RetroVibe and want to have it upgraded, you can ship it over to us and we can install the upgrades for you. Read the FAQ page for more information.


“I have been using a univibe Clone since the early 90’s live. The RetroVibe is right on track with the perfect sound we’ve all heard and love. It’s way more faithful and musical than other vibe pedals out there.”
J Mascis (Dinosaur Jr.)

“I love the Retrovibe! It is a magic piece of equipment !” Ruban Nielson (Unknown Mortal Orchestra)

“The Retrovibe is my Vibe of choice. It has all of the “Vibe” of the original, particularly that illusive, complex midrange that responds so beautifully to pick attack. It behaves perfectly with Fuzz Face type pedals and is more transparent than any of the old Univibes I have heard. That it is so compact is quite a bonus and mine has Laurel and Hardy on it (I got lucky – the rest of you get flowers, Ha!)Julien Kasper
