Ok pretty sure this riff is right, but it is rather difficult to play:
[C]: [F]: [Bb]: [G]:
e|--3--3----8--8----1--1-----3--3------------------------------------------|
B|--5--5----10-10---3--3-----0--0------------------------------------------|
G|--5--5----10-10---3--3-----0--0------------------------------------------|
D|--5--5----10-10---3--3-----0--0------------------------------------------|
A|--3--3----8--8----1--1-----2--2------------------------------------------|
E|--3--3----8--8----1--1-----3--3------------------------------------------|
As far as i can tell it is played on electric with a compressor/limitor.
