Profile: MXR was a Rochester, New York-based manufacturer of effects pedals, 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, which continues to produce the original effects units along with new additions to the line.

Since 1972, MXR has been a pioneer of the effects pedal market with the revolutionary development of tough and rugged stomp boxes, simple utilitarian designs, small sizes, and 100% rich analog tone. Today Dunlop continues MXR's traditional pedal line of original MXR classics that has come to define the brand, as well as new modern classics like the Carbon Copy and Fullbore Metal. However, MXR has never stopped innovating and continues to inspire with award winning designs. MXR Bass Innovations has recently released the Bass Octave Deluxe and Bass Envelope Filter with both pedals winning Editor Awards in Bass Player Magazine, and Platinum Awards from Guitar World Magazine. The MXR Custom Shop faithfully resurrects recreations of the long-lost vintage models such as the hand-wired Phase 45, as well as doing limited runs of pedals featuring premium components and highly modified designs such as the new Custom Comp.
