The Friedman Butterslax Bill Kelliher Signature Guitar Amp Head is an amplifier built to help you get the tone you hear in your head — supplied as genuine Australian stock with local warranty. Handwired Bill Kelliher's guitar playing is rooted in metal, infused with rock 'n' roll, progressive rock and sprinkled with bits and pieces of thrash, punk, and psychedelic-ness.
