This is the bass thats played throughout the song... pretty easy...

  (Ring out-------------------------------------------|


During the verses, I just played this in the background. You can strum both of them as 
many times as you want, it will probably sound sweet.

e|6------------------------5------------------------|
B|7------------------------6------------------------|
G|8------------------------7------------------------|
D|8------------------------7------------------------|
A|6------------------------5------------------------|
D|--------------------------------------------------|


And then for the chorus, you can play this picking part.

e|--6-7-6---6---6-6-7-6---6-------------------------|
B|4-----------------------------x3------------------|
G|--------------------------------------------------|
D|--------------------------------------------------|
A|--------------------------------------------------|
D|--------------------------------------------------|


and then on the last one...


e|--6-7-6---6---6-6-7-6---6-------------------------|
B|3-------------------------------------------------|
G|--------------------------------------------------|
