At the moment of writing, I'm like 10% into knowing what this pedal can do. But to keep it short, the fuzz itself is nasty, dirty, gated (above 50%-ish) and disgustingly awesome. The filter (HP/LP switch, HPF/LPF knob, Sense knob, Resonance knob) offers so many crazy synthy sounds, or just tweaked fuzzy sounds, that it's ridicoulous. This is easily one of my best buys ever, and I've just scratched the surface so far.
