Premier Guitar has uploaded video footage of Phil Demmel of San Francisco Bay Area metallers MACHINE HEAD demonstrating his new PDXT Demmelition King V guitar from Jackson at the Musikmesse Frankfurt 2013 fair, which took place April 10-13 in Frankfurt, Germany. Check out the clip below.MACHINE HEAD last week celebrated the tenth anniversary of Demmel becoming an official member of the band. Demmel joined MACHINE HEAD a decade after his previous band, VIO-LENCE, broke up; VIO-LENCE being the band that he and Rob Flynn, MACHINE HEAD's lead singer and guitarist, launched together as teenagers. Robb went on to form MACHINE HEAD in 1992 and Phil joined them in 2003. MACHINE HEAD in February parted ways with bassist Adam Duce. The band's guitarist/vocalist Robb Flynn explained in an online posting: "We may have fired Adam on [February 11], but Adam quit MACHINE HEAD well over a decade ago. He just never bothered to tell anyone… but we all knew it." A replacement bassist has not yet been announced.
