MXR was originally founded in 1972 and then acquired by the iconic Jim DUNLOP Company in 1987. The pedal line has continued to grow yet you can still get the MXR Classics that have come to define this brand. You can find guitar and bass effects pedals in the brand lineup. The MXR custom shop line is responsible for recreations of vintage hand-wired models. Pick out a MXR pedal today!
