guitar 2 does the main riff
e|-------------------------------|
B|-------------------------------|
G|-------------------------------|
D|-------------------------------|
A|-------6-------4h5-------------|
E|3----------6-----------4-------|
in this part of the solo:
G|6-7---6-7-|
D|----8----8|
guitar 2 instead of the hammer-on interrupts the riff with:
A|4-5---4-5-|
E|----6----6|
and ends doing the same notes like guitar 1 but one octave lower
