Anvil - Metal On Metal Chords & Tabs

i didn't find any tabs of this song on here so i decided to post this.

The main riff goes as following:

E---------------------------------------------------------|
B---------------------------------------------------------|
G---------------------------------------------------------|
D-3--3--3--6--6--3--3--3--8--8--3--3--3--6--6--3--3--3--2-|
A-3--3--3--6--6--3--3--3--8--8--3--3--3--6--6--3--3--3--2-|
E-1--1--1--4--4--1--1--1--6--6--1--1--1--4--4--1--1--1--0-|

[ Tab from: https://www.guitartabs.cc/tabs/a/anvil/metal_on_metal_tab.html ]
i'm not sure how it goes through the verses,so i just play the main riff with the F5's muted.


Then the riff after Verse 3 goes:

E---------------------|
B---------------------|
G---------------------|
D-3--3--3--3--3--5--6-|
A-3--3--3--3--3--5--6-|
E-1--1--1--1--1--3--4-|

E---------------------|
B---------------------|
G---------------------|
D-3--3--3--3--3--3--2-|
A-3--3--3--3--3--3--2-|
E-1--1--1--1--1--1--0-|


that's about all i learned of this song so far.i'll transcribe more of it when i learn 
of it.
