I made this tab after seeing the other tabs available for this song; they were good, but bits and pieces were missing. I have taken all the main parts from the other tabs, and compiled them in this tab, to save people from having to move around the tab archive too much. I give full credit to those people whose tabs i have used: 
Chris Frazier
Rory Mckee
Basheesh
Also, full credit to Slipknot for actually making this song.

Slipknot Guitars are tuned Drop D and a full 1 & 1/2 step down.
