In the early ‘90s Dave Friedman became known for modding wizardry on various Marshall amps, gaining a following that included Eddie Van Halen, Steve Stevens, and George Pajon.
His exploits led him to form Marsha Amps in 2008 – which didn’t go over too well with Marshall, who told Friedman to cease and desist. He renamed the company after himself and quickly found success, establishing signature amps for Jerry Cantrell, Chris Shiflett, Steve Stevens, and others.
