This is dull boy, but a 4 string version, because i know that everyone doesnt have a 5 
string bass, if you can, Please rate this tab, i want to see how i'm doing with my tabs. 
I hope you benefit from this tab, and good luck playin this song.
Key:
P = pop
S = slap
blank = normal strum
\ /= slide down/up
? = do what ever feels right, because i just cant quite tell
=== = hold
Tuning: (High to low) G-D-A-D
(after 13 second vocal intro)
