All dja been said I think ^ ^

UTILIZATION

Good galley is to find THE SOUND but once you hold it you keep it for life, swore lol
seriously have to be patient in life, things come to those who wait (translation seeks an hour or two and you will dégouter all your buddies with your metal zone ^ ^)

SOUND QUALITY

So here to answer all the advice already given to stop criticizing, she call'd metal zone c not for nothing, so its heavy metal, huge distortion, ca pulse, etc ...
if you want to play the blues or pop rock on foot is not a metal zone called, must stop there ...
Then in terms of its "cool, well I think it's a style of his that we should not reject, is not that the hot lights in life. Cahcun his thing. METAL For the c better (unless you have a MESA, let's face it lol)

OVERALL OPINION

I ale a year and I am well, the advantage is that I have tried on many amps and little variation closely with the same setting was the same sound, the amp does not play not a big role. (tried it on and WARP7 MG100fx Marschall and a peavey forgot the model, also 100 watts)
As for the "poor" (like me) who play on chti amps (watts Marchall ...) as well say that even when AC pulse and it's really excellent, nothing to do with the crummy original saturation of the c excellent amp and there, for I confess against jlai purchased new and it's been expensive .. but after jle said jpeut do without it and without it the sound of my amp would have made me stop the guitar ... here
