I figured this out on my own. In my opinion it sounds awesome, but this is my first tab 
so bare with me. Its just 2 different types of chords so its very simple.

E--8-----6-6-----6-----4-4-----8-----6-6-----8-----8--8---8
B-10-----8-8-----6-----4-4-----8-----6-6-----8----10-10---8
G-10-----8-8-----7-----5-5-----9-----7-7-----9----10-10---9
D-10-----8-8-----8-----6-6----10-----8-8----10----10-10--10
A--8-----6-6-----8-----6-6----10-----8-8----10-----8--8--10
E--8-----6-6-----6-----4-4-----8-----6-6-----8-----8--8---8

And this just repeats 4 a while. Good luck. please leave comments.
