Zakk and much less Fox were nothing compared to Jake in pinching or any other aspect of the guitar. Enough said:
Sorry, but I am afraid you are mistaken when it comes to that particular technique. As I stated. I prefer Jake, to begin with, but Oz Fox and Zakk Wylde (at least early in both of their careers) really showed me how to master pinch harmonics as a great technique when writing both riffs and solos. It certainly is not as important of a tool for me as it was/is for Oz and Zakk, but they could come up with some of the most unique sounds from that technique.
