Main Lick:

G----7p5----------5--------------------------------------------------------|
D-------------7----------7s5---3h5---3--0---4--0--0--0--0--4--0--0--0--0---|
A--------------------------------------------------------------------------|
E--------------------------------------------------------------------------|

Repeat it 12 times.

It’s hard to show timing with tab, so listen to the recording to get the feeling since the number of D’s at that end part could be wrong. I think he plays a couple more than four before going back into the beginning of the lick.

Funky Disco Part

The part after that main lick is just Brock pickin’ at that open D and throwing in that F# at the fourth fret.

Brock is using a D power chord behind the other guys’ solos the whole time, and once you get the rhythm of it, it’s just repeated throughout until the return to the main lick at the beginning.
