Morbid Angel - Opening Of The Gates Tabs

MORBID ANGEL


Tuning - Bb


pm - palm mute
p  - pull off


*NOTE* Either my hearing is going sh*tty or I'm starting to
lose my guitar skills but there are a few riffs in this song that I 
couldn't get so any help in finishing the rest of this tab would be
greatly appreciated. There was lots of request for this song and I
tried my best so anybody that wants to help out in finishing, be my guest.
Also, I'm horrible at timings in tabs so, listen to the song to get
a better feel of the riffs contained within this tab. Sorry for the long 
if you have the riffs that aren't done or corrections, email them to me and 
I'll make a new tab with the riffs added and your name will be credited on 
the tab. Thanx alot for waiting ppl.

 
This song is played on a 7-string tabbed on a 6 string
