Analog technology has based optocells as the original.
MXR big size, like all pedals VoodooLab ...
Super simple setup, connect, turn the knobs. Nothing extaordinaire .....
The effect is supposed to replicate the expensive Univibe effect Jimi Hendrix and Robin Trower (listen Machine Gun or live in Woodstock ....) ... It does the job, I also have a Mini Deja Vibe, the sound is very very close. but I noticed that the Fulltone was noisier when it is associated saturations. It is also more voluminous ... So I kept VoodooLab, the Fulltone is for sale. allow the knob to control a roughly parameters foot, practice.
I've had four months, delighted, I gained up by the report and the Fulltone Honestly, kla difference in sound is not clear, the effect Hendrix sought is there ...., added to that the silence of the effect, the relatively compact body compared to other univibes (except Lovepedal pickle vibe) This is perfect for me. The Fulltone has an advantage anyway: the speed knob is large and very well placed for easy adjustment to the foot.
