This is not even a raging metal distortion. It's just a nasty buzzsaw. It can be cool, but is usually abrasive. This pedal is incredibly simple to use. The pedal is of course very noisy, as that's the point.
Single notes sound great, but chords tend to get lost.
But you don't buy a fuzz pedal the size of a saucer to get rich, harmonic sustain. The main problem I have encountered is occasionally when the effect is turned on, the signal volume is drastically lowered. This really sucks, cause you're all stoked to turn it on and let it rip, and you signal gets quieter. I wouldn't use this for a gig, due to the aforementioned volume problem. I would have to be constantly adjusting the volume, I love using it for recording, it gives an incredibly fuzzy sound.
