Unless you want to jump on your pedals or you kick them or play soccer with them, AND EVEN THOUGH i believe this pedal will resist the stomps you might give it.
Yes, its made of plastic. A hard one though.
No, it does not hiss in normal parameters.
If you use it with an amp that has gain and distortion already and you crank the distortion on your pedal it might throw some noises, but this is normal on any pedal. You just have to use it as a normal pedal.
The output and the wide range of tones and distortions that you can get (not even mentioning that the sustain its PRETTY SOLID) makes this pedal perfect for some metalcore/deathmetal/deathcore and if tweaked correctly for even rock music. (Trashmetal will always be possible cracking everything up)
Nothing to envy to other distortion pedals like MZ ;)
