This song relies alot on having both guitar and bass play different
parts at the same time, but I've fashioned a little acoustic version 
here that allows you you fit in the bassline to make it sound good
played just on one acoustic. Don't expect the the tab here to sound
perfectly similar to the original, but I did my best.  

Tuning: AACEBE

h = hammer-on
p = pull off
x = mute this string

Then, go through the next verse playing what you played in "VERSE WITH
BASSLINE" and play around with it your own way, get another chorus in
there, and you're done. Hooray.
