== History == MXR co-founders Terry Sherwood and Keith Barr met as high school students at Rush-Henrietta Senior High School in Henrietta, New York, a suburb of Rochester, New York. Together they started Audio Services, an audio repair business, where they repaired stereos and other music equipment in their rented basement apartment. This experience led them to form MXR and they began producing their first original effect pedal design: the Phase 90. This was quickly followed by the Distortion +, Dyna Comp, and the Blue Box. Michael Laiacona joined this early MXR team in a sales position. Barr later left MXR and went on to found Alesis while Sherwood and four managers/engineers of MXR, John Langlouise, Phil Betette, Tony Gambacurta and Richard Neutrour, co-founded Applied Research & Technology. Mike Laiacona and his wife went on to found Whirlwind USA.
