Everything has been said and explained well by my colleagues below.

UTILIZATION

Very simple configuration, no need for manual, easy to use but actually, if we could change effect with a footswitch would be delighted.
This is the only pedal my pedalboard for my PSU which is inconsistent because in AC, why make it simple when it can be different from others

SOUND QUALITY

- The Harmonizer is nice, its a chouille imperfect and I love it.
- The effect whammy worked wonders, however, I agree with other reviews. Once you lose the pedal triggered the attack, as if a compressor was built.
- The Dive Bomb effect and Drop Tune are a little "gadget" but hey it could always be useful, Tune Drop me a lot already used to mimic the effect of the floyd rose I did not: p

OVERALL OPINION

I use it for one month only, but fairly intensive. There is no real competitor for the whammy effect, on the other hand at harmonizer find even better known.
I am very satisfied with my purchase, but when you put € 180 into a pedal they hope to change presets without having to stoop and a by-pass quality.
