my first tab...but i think it's right...

the riff goes through the whole song

E|---------------------------------------------3-3-3-3-3-3-3-3-|
A|5-5-5-5-5-5-5-5---------------3-3-3-3-3-3-3-3----------------|
D|---------------2-2-2-2-2-2-2-2-------------------------------|
G|-------------------------------------------------------------|

variation (after 2 times main riff):

E|-----------------------------------------------------15-15-15-15-15-15-15-15-|
A|5-5-5-5-5-5-5-5---------------15-15-15-15-15-15-15-15------------------------|
D|---------------2-2-2-2-2-2-2-2-----------------------------------------------|
G|-----------------------------------------------------------------------------|

that's it...enjoy it

stay evil!
