Watch the Single Stringer online guitar lesson by Angus Clark from Essentials: Neoclassical Rock Soloing

In the accompanying video, there's a nice explanation of how the single string pattern works over the chord progression. Technically there are some interesting fingering choices during this section.

The string skipping section has a similar explanation that has a pretty cool segment about how an A diminished triad can be applied over both an F7 chord and an Am7b5 chord - gives you something to talk about with your jazz friends.
