I think that josh actually plays this in standard C tuning, but i've tabbed it in 
E, i.e. EADGBe, to save you the effort of re-tuning.

Main Riff:

--------|
--------|
---3----| x how ever many times josh plays it
---5----|
---3----|
---3----|
Listen to the record for the rythyms, as it changes throughout the verse, but it's 
just this chord.

Chorus:

Note - 5^7 means bend 5 up to 7
----------------------------|
--------------------3---3---|
--------------------5^7-5^7-|  x 4
--8-----8-----8-------------|
--10----10----10------------|
--8-----8-----8-------------|
"sick  sick  sick"

bridge riff:

-6p0-6p0-8p0-8p6-8p0-0-10-10p0--|

and that's all the part's you need. Hope you enjoy!!
