Melody

e--3-3-3-3-1-----|
B------------3-0-|
G----------------|
D----------------|
A----------------|
E----------------|

when you have done this tact you can start from the begining (not intro)
and play untill the comp change, but instead slow down that tact and when the "3" is do 
this
                         |
                         V
e-----------------|    ----------------|
B-----------------|    ---1------------|
G--------------2--|    ---0------------|
D-------2--3------|    ---2------------|
A--"3"------------|    ----------------|
E-----------------|    ----------------|

and with the melody skip the 1--3--1 (there is stands that the comp change)
and wait to next tact and do at the same time as the comp guitar.
