Guitarist Peredur ap Gwynedd plays through Hughes & Kettner CC 412 A 30s miked with Shure SM57s. According to guitar/bass tech Adey Wilson, at the core of Gwynedd’s electric guitar rig is a TC Electronic G System. “The ‘brain’ is separately rackmounted and connects to the foot controller via a Cat-5 link,” Wilson says. “It switches the Hughes & Kettner preamp channel-select to the desired sound/recall settings and interfaces.”
