Oscillation picking is like alternate picking in a circular motion to conserve the use of energy that normal back-and-forth motion uses.

Oscillation from fuzz is a sort of feedback, I think. Matt Bellamy does it from time to time with his fuzz factory (Plug in Baby intro, for example).
Do you have any good guides to teach me?

and why is oscillation a good?

And what are the benefits of using hollowbody/semi hollows?

Thanks so much!
