HAve fun playin this tits song

7 Nation Army by White Stripes

D--2--2--5--2--0------

Thats just the basic riff which is done almost all the way through the song. To tell the truth it isnt actually bass cos they dont have bass but JW has this wierd sfx thing on his amp so he can make it sound like bass. it sounds better on bass anyway.
ENJOY!
