MXR
company

MXR is a New York–based manufacturer of effects pedals from Rochester. The company was co-founded in 1972 by Keith Barr and Terry Sherwood and incorporated as MXR Innovations, Inc. in 1974. The MXR trademark is now owned by Jim Dunlop.
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.
Begin with the source’s own compact description: “MXR” is company. The dossier treats that line as a proposition to test through company, not as a finished interpretation.
Why this record matters
The phrase “company” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Aug 19, 2026. The linked authority identifier is Q974486. 2 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1972 and 1974.
Official terminology may obscure informal participation, dissent or communities documented only indirectly. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
