You know I'm trying very hard to find a video to teach me what it is exactly that Kirk is doing. BUT..... The closed thing I have found.... Go to Youtube and look up a song called "Sacrificed sons" by Dream Theater. When John Petrucci (the guitarist) play's his solo you will see him use the W/bar, take the High E string and connect it to the pickup. So I'm thinking if you mix the Dimebag Scream with what John Petrucci is doing in that song......You might get an Idea. Good luck and Let me know if you find out exactly how to pull this off.
