Guitar Zen: CAGED
A very helpful presentation of CAGED because it presents relatively simple slow leads and relates them clearly to both major and minor chord shapes (popular music is mostly major chords). The stated goal is to keep you oriented around the chords and for me that approach worked very well. My only suggestion would be to explain a little more when the lead departs from the pentatonic (I guess that's another lesson - adding interest, bending the bars on the CAGED system). But the fact that I recognize these departures means I am oriented around the chords and CAGED shapes, the course did it job.
