Distortion with two modes (overdrive and distortion)

Strong point, a semi parametric equation to the proper awesome sound


Easy to use, from a little time to set the medium range, we arrive quickly at a good sound.


I love this pedal. Adapted to the big rock with a marshall its type. Warning, this is not a metal pedal nag, the metalheads will be disappointed. Good on any amp, especially lamp, get the sounds of ACDC with gun & roses's very realistic.

It meets very well the character of the guitar.

Lacks a little sustain, for it provided a boost compressor or upstream.


Well this pedal it's been 3 years that I have and I always come back. I use a mesa boogie F30, the channel clear for a preset distortion of less typical mesa. It has nothing to be ashamed of the channel distortion of the mesa yet very good.

In the long run it will be a permanent part of my set;

I strongly advice to all that big rock.
