SOUND QUALITY

The effects are they effective, responsive and realistic enough?
The range of effects is there for all tastes. I have not tested everything, but there is everything there that we really want.  Maybe not enough for the sound engineer perfectionist, but for a live / or a practice room it is nice.
Large distortions and hi gain amps often require the noise gate, but it is also very effective (3 different noise gates were modeled).

Which instruments do you use?
Guitar only.

Which ones you prefer, you hate?
The auto wha is nice, there are good distortions, the chorus. flange is convincing.
Not much to complain about.

OVERALL OPINION

How long have you used it?
It'll be two weeks, for use under 5 hours.

What do you like most and least?
Navigation between the pedals ... or rather the lack of navigation. We chose the pedal in a list in bulk, it deserves to be split into categories.

Have you tried many other models before buying it?
Several different brands (Boss, Digitech, Line6 ...) but the same attention (mostly repeated in fact) ... when the sound is not what I want, while the ... all parameters are accessible, easily, quickly. Truly effective, and the only alternative to expensive Line6 M9, all in a compact body.

How would you rate the quality / price?
Hard to beat. Excellent.

With experience, you make this choice again? ...
It is too early to tell, but at first sight, nothing to regret, and certainly not an alternative. The M9 needs to be tested, but at a higher price.
