The thrash-metal vets keep it simple yet high-tech on their 2015 tour.
Peterson keeps it consistent and affordable on tour by leaving his Marshalls at home and running his guitars into a Line 6 Relay G55 wireless feeding a Kemper Profiler PowerHead that’s driving an EVH 5150III 4x12 loaded with Celestion Vintage 30s. All his effects—including wah—come from the Kemper, which Peterson controls with a Behringer FC1010 MIDI foot controller.
