The Minor Pentatonic scale is the bases of most Heavy Metal, Rock and Blues.
You can hear it used by most artists from Chuck Berry to Van Halen.
Finger patterns of the Pentatonic scales on the Standard guitar built around each minor chord position is commonly referred to as a Box.
The beauty of Box playing is that you can learn one or two boxes and pretty well have the ability to play most Blues and Rock. I am not suggesting by any means you stop there but it is a very good start.
My approach to playing Blues and Rock is to adapt the Boxes to E9 PSG in the same manor they are used on the Standard Guitar in that you build the boxes around the Minor chord positions and play the scale in the usual manor you would play E9 by playing the scales within the each Box using pedals and levers to form the Pentatonic scale. This in no way means you can't move the bar around in each box instead of using pedal in fact I encourage using both.
The first example below is comparing the Standard Guitar Boxes to the E9 PSG Boxes.
The second example is comparing the difference between the Standard Guitar and the E9 PSG in how you can play the scales within each Box.
