MXR Innovations began in 1972 as a manufacturer of guitar pedals. The company was co-founded by innovators and audio pioneers Keith Barr and Terry Sherwood when they were teenagers. Dunlop Manufacturing now owns the MXR trademark and continues production of the company’s popular effects units.

It all began with just a few dozen Phase 90 MXR guitar pedals, which the partners built in a basement and sold out of the back of a car at local gigs. The Phase 90 went on to achieve greatness by providing the unique tone heard in most of the songs on the iconic Van Halen 1 album.

By the time the company added the Blue Box Octave Fuzz, the Dyna Comp Compressor and a Distortion pedal to its lineup, it was well on its way to becoming a leader in the industry.

In the early 1980’s, MXR released the Commande Series, a line of pedals made of polycarbonate priced to compete with less expensive imports coming from Japan. This was when the company moved to a large footswitch and moved the power, output and input jacks on top of the case to allow musicians to group their pedals more tightly on the floor.

As other manufacturers started to catch up, MXR was forced to close its doors. Dunlop acquired the brand in 1987 and, after offering the classic options, including the Phase 90, began to add new products to the line. The Smart Gate Noise Gate and the Carbon Copy Analog Delay are now considered modern classic effects. MXR has also developed numerous signature effects working in collaboration with Eddie Van Halen, Zakk Wylde and other noted guitar virtuosos.
