both guitars repeat till end. 3rd guitar play little riff: 

E|--6-5-3---3--------------------|
B|--------6----------------------|
G|-------------5-3---------------|
D|-----------------5-5-3-5-------|
A|-------------------------------|
E|-------------------------------|
or something like that. nothing fancy. 

as for the chorus that whiney sound you hear i really 
don't know if thats a guitar. this riff sounds close to it 
but there's deffinately a bit missing. its more than one note 
im pretty sure.
