Tune down a whole step for it to sound great. it 
doesn't sound wrong without dropping
it, but it sounds better a step down. It's played the 
same both ways.

[------0~-----------0~-----------0~~-|-1~/4]
[------0~-----------1~-----------3~~-|-1~/4]
[------0~---------2------------4-----|-2~/5]
[----2----------3------------5-------|-3~/6]
[--3---------------------------------|-3~/6]
[------------------------------------|-1~/4]

after that I'm not perfectly clear... just fiddle 
around with regular chords for a
little until the chorus breaks in, but I'm not sure how
 to play that yet.
