The Emma Electronic PisdiYAUwot metal distortion pedal is a must have if you are into metal or at least into heavy riffing rock.

By the way, the name "PisdiYAUwot." What does it mean Angus Podgorny? It sort of means a contraption-with the difference that the PisdiYAUwot pedal is a contraption that actually does work!

One thing Emma Effects thinks that no one has really nailed yet, is a great pedal for metal. Most of them seem to be either too muddy or too slow for the really fast riffs. Emma's goal was to build a pedal with low-end punch that resembles beating sheet metal with a big hammer, the ability to scoop mids the Dimebag way, and to push up the mids the NuMetal way-full mids with body, that is.
