Since our beginning, over half a century ago, Electro-Harmonix has led the way as an innovator in the world of music. Our founder, Mike Matthews, wasn’t striving to become a worldwide influence. He simply wanted to break barriers, and allow freedom of sound. Electro-Harmonix liberated musicians of yesterday and this culture of change continues to produce innovations that rock the world to this day. We are honored to carry on this legacy; pushing boundaries aside, empowering musicians of every level, and changing the way music is made, forever. Electro-Harmonix is a New York-based company that makes high-end electronic audio processors and sells rebranded vacuum tubes. The company was founded by Mike Matthews in 1968.
