MXR

The company was co-founded in 1972 by Keith Barr and Terry Sherwood[1] [2] and incorporated as MXR Innovations, Inc. in 1974.

This experience led them to form MXR and they began producing their first original effect pedal design: the Phase 90.

The "Box logo period 2" started in early 1981 and went until 1984, when the company stopped making pedals.

In 1981, MXR introduced the Commande Series, a line of plastic (Lexan polycarbonate) pedals.

The input, output and power jacks were all moved to the top of the case to allow a tighter grouping on the floor, or pedal board.

In late 1983 MXR announced a digital sound effects pedal generator simply known as the Junior.

MXR also had a line of professional rackmount effects used by the likes of David Gilmour,[6] Stuart Adamson and Mike Rutherford.

Since 2006, the "M-181" product number has been re-appropriated by Jim Dunlop for the MXR Bass Blowtorch Overdrive pedal.

the frequency response of a system can be tailored to compensate for room acoustics, speaker aberrations and program material.

Horizontal control placement and the equalizer's compact case permit easy manipulation in studio mix down situation.
