This is played with 8-string guitars on ½step down tuning. I didn't find this tab anywhere. I watched Meshuggah's own lesson for this riff and it like this. 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. Hope you get it :)
