In the first part of the solo, we begin with a classic Texas bluesline, a minor third with some heavy víbrato. It's all in triplets, to keep that groovy shuffle feel.
The second part includes an almost country'esque little idea. As mentioned in the video, much of the lines and licks in southern rock and blues borrows heavily from country, just that it is played in shuffle and with distortion. Basically, you can take almost any country idea and turn it into a long-bearded rocking lick! Again, we're working with both pick and fingers in this chicken-picking style.
