Configuration is very simple, two buttons and a switch that lets you choose between two modes ("normal" and barred from any other property type transistor grotty well). I have the new version that does not correspond at all to the picture ...
The one thing that could be considered negative is that the octave effect reacts differently depending on the location of the handle or it is (it really becomes audible from the 12th box wholesale), but hey I ' imagine that it is best to imitate the original Univox
The sound is excellent, I have not had hands the original Univox (but if I compare over demos on you tube, it is really very close).
Excellent for sounds ranging from who (live in leeds by example) to the smashing pumpkins (you can hear it on siamese dream for some passages).
We can go a fuzz sound "traditional" to the heavy artillery.
It is a fuzz with a light octave above (but much less pronounced and more usable than octavia example) the octave means especially when it exceeds half of the handle.
I have lots of fuzz and this one is really interesting as we move away from big muff fuzz face or another, thanks to this pedal, it may sound impossible to have with more traditional fuzz as those cited above, and much easier to use than the fuzz / octave messy that I find the game you can go solo riff game when we want her to spit.
Very good pedal very special.
