KMA Audio Machines Guardian of the Wurm Dist.

Pros: unique distortion, nails the chainsaw distort sound. Probably one of the most interesting and versatile pedals I came across. Excellent build quality and again the sound is raw and earthshattering.

Cons: You may want to invest into a amp attenuator if you have a loud amp, this pedal is extremely loud not to be used in a "bedroom" noise level scenario.
