Late Pantera guitarist 'Dimebag' Darrell Abbott claims yet another victory in our Greatest Metal Guitarist competition over one of his best friends, Zakk Wylde. Dime has been an early favorite since the beginning, defeating Dillinger Escape Plan shredder Ben Weinman and Korn's Brian 'Head' Welch before moving on against Wylde. The crunch-master moves on to the Semifinals.

Dream Theater's John Petrucci is unquestionably one of the world's finest players. However, godlike chops don't always work against a behemoth like Metallica's Kirk Hammett. Dream Theater fans, however, showed up in droves and earned Petrucci another win. With Vivian Campbell, Eddie Van Halen and Kirk Hammett disposed of, Petrucci comes face-to-face with Dimebag.
