Otherwise the usual pressure with a ca and as the knob FREQUENTLY tone went crazy (ho ho ho! The pun!) When it exceeds 5 / 6.
A good distortion with a very fine grain, but too "constant". (/! Maybe that therminologique music professionals will not understand what I will try to explain!) The action of the drive knob does not seem to change the saturation level but rather the presence of the latter (c ' is why I talk of a grain "constant") I have not managed to get a crunch sound that is a shame especially for a versatile pedal judged by the brand.
I use it for a little over a year.
I love the sustain and it fills me to the tall and aggressive riffs but I regret that it does not crunch!
(And this remark will apply to most secondary effects of the brand: they could work a bit more design in Proxon! Left to play as the vintage play anywhere, a more oldschool graphics give them more classroom)
