Ok here is a new tab. I previously wrote the other one but this one is more accurate. 
of playing open chords there actually is like 3 guitars by the sounds of it but it might 
be 2. listen to the song to match up.


intro and verse
guitar I (power chords)
e|---------------------------------------------------------------|
B|---------------------------------------------------------------|
G|----------------7----------------------------------------------|
D|---7------------7----------4---------------7-------------------|
A|---7------------5----------4---------------7-------------------|
E|---5-----------------------2---------------5-------------------|


guitar II. play open A chord every time guitar one hits the next power chord


chorus: guitar I plays same chords but faster strumming. again listen to song for it.
here is where it sounds like the song has 3 guitars because Guitar II either does the 
thing as he did before (the exact same thing) or Guitar II plays this part. through the 
chorus.

chorus                  outro
e|--------------------|-------------------0--|
B|--10-9-7------------|-10-9-7------------2--|
G|---------9-7-6------|--------9-7-6------2--|
D|---------------9-8--|--------------9-9--2--|
A|--------------------|-------------------0--|
E|--------------------|----------------------|


outro: guitar one does same thing as chorus but guitar II plays above line on the last 
of the song
