I'm trying to reproduce this Metallica riff (from the song Day that Never Comes):
|------------------------------------------------|
|------------------------------------------------|
|7----/9-----------------------------------------|
|--------7-----7--/9-----7-----------------------|
|5----/7-----------------------------------------|
|--------5-----5--/7-----5-----------------------|
I noticed that Kirk (lead guitar) isn't picking strings 6 and 4 separately.
So my question is: How can play this riff with one strum? Should I mute the 5th string?
