UTILIZATION

No need for manual even my grandmother would put mre on the way, the diversity of possibilities is the word of the cl of distortion pedals ... The sound changes Fawn enough magic throughout the handling of pots.

SOUND QUALITY

This is just personal opinion, but I think this product sounds PDAL trs drafts ... and the noise level and stop rllement when he is asked too much ... I think it is not at all what I was looking ...

I test on a 1000 Fender RockPro, and a Marshall JCM 2000 DSL100 with my les paul classic double cut (micro needle: 57 'classic plus)

I ended up with a much more runny than the distortion of my amp, and not all need more powerful ...

OVERALL OPINION

I'll Sparer because it does not stick at all my musical style ...
I like the price and cons by the versatile object (it's a little magic ...)

I will hide me today on a Big Crush Compressor Rocktron home to get what j'esprais have with the Turbo RAT from home ProcoSound ...
