Matthews Dave - Stay Or Leave Tabs

(Riff)
I was sitting around trying to pick this great song out. 
I have the bass line down but there is a little 4 hit strum 
at the bottom that I cannot figure out
(Similar to the Crash style but not quiet)
I need help!!! 
Here is the bass line.
If anyone can figure out the bottom 
I would love to hear from you. 
Good Luck!!
