Took me a while but here you go.
I tabbed this from the live videos on YouTube so it wasn't too easy to tab lol.
Tabbed from this video: http://www.youtube.com/watch?v=RZrfHAZ4yNo
But I'm 98% sure I'm right.
Just in case I put something wrong or in a different spot, please tell me!
I wrote this down on paper and I could have possibly put notes on the wrong string...
I just skipped some fast hammer-ons and pull-offs in the bridges because they were too 
to tell and I was lazy :P
Jeph Howard is an amazing bassist
p.s. please rate and comment to tell me what you think!

Enjoy!

know? Probably not...)
