Everybody don't have 8-string guitar, but this is right tab for 8-string guitar.
Rhythm is ooo-o-ooo-o-ooo-o-ooo-o-...... etc
5/ means you have to bend fifth fret.
Eb-----------------|
Hb-----------------|
Gb-----------------|
Db-----------------|
Ab-----------------|
Eb-0------0-----0--|
Bb----5/-----5/----|
F------------------|
I don't have time to tab whole rhythm and bending. hope you understand that way.
Then the lower part of the riff goes like this for real
Eb-------------------------------------|
Hb-------------------------------------|
Gb-------------------------------------|
Db-------------------------------------|
Ab-------------------------------------|
Eb---------------------1--10--4--------|
Hb-------------------------------3--0--|....
F--1-------------2--5------------------|
so, strum that certain fret for the certain rhythm.
PLAY TOO ..
