This is my first tab so  apologize for any mistakes and any corrections would appreciated  :)
The riff is a bit tricky but it's really cool when you can play it up to speed
I don't really know how to explain where your fingers go but they start with: 

thumb- E, A and D strings
index- G string 
middle- B string
ring- e string

Standard tuning

e|----------------------------------------2-----------------------|
B|--------3-------------2-------2-------------3---------2h3---3p2-|
G|------------4---------0-------0-------2-------2-------2-----2---|x2
D|------4-------4-------------------0-------------------2-----2---|   
A|--2-----------------------------------------------0-------------|
E|------------------2-------3-------------------------------------|

On the second time he plays the open e string near the end after the '3p2'
