with distortion this sounds ok, but I prefer to play doublets (when you play, play the 
fret, just on the string below it as well) so the tab for that would be something like this

E---------------------------------------------------------------------------|
A----------------------------6-6--------------------------------------------|
D-----------------6h8-8-6-4--6-6--------------------------------------------|
G--6h8-8-6-8-8-8--6h8-8-6-4-------------------------------------------------|
B--6h8-8-6-8-8-8------------------------------------------------------------|
e---------------------------------------------------------------------------|

this gives it a much fuller sound

rock on! God Bless all you cowboys like me you there
