One of Zakk's signature techniques is the pinch harmonic. Listen to any of Zakk's heavier playing, including his take on Crazy Train, and you'll hear this fun sound. You might've also heard it while listening to Dimebag Darell of Pantera. Zakk and Dime were good friends, so it makes sense that their styles influenced each other.
Countless students have asked me how to do pinch harmonics that I decided to write this post on exactly how to pull it off, with an easy step by step guide, and a few photos for reference.
