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.
