I'm not far along yet to do full songs. Lately though I've been learning riffs to AIC 'Would', Metallica 'Master of Puppets', VH "Unchained", Metallica "One", 311 "Down", KSE "Rose of Sharon"
That had me curious as well so I ended up finding that same vid you posted. Looks like sweep - pull - sweep - pull like you said. Do you know what that stomp box he is hitting on? Can't be a boost. NS-2 noise surpressor maybe? It can't be his MXR Wilde pedal as I can't imagine he would be turning that on and off like that
I love working on KSE riffs (mostly ROS and My Curse). That pre chorus riff where it goes bump-bump-bump, bump-bump-bump, x4 I can't play like the tab shows so I have to switch it up bit
