This year marks the 40th anniversary of MXR’s incorporation in 1974. To musicians across the world, those three letters have come to represent innovation, inspiration, and rugged reliability. MXR has never stopped innovating, and Dunlop’s stewardship of the brand has seen the faithful reintroduction of its most iconic pedals—from the Phase 90 to the Dyna Comp Compressor—as well as the development of modern classics such as the Carbon Copy Analog Delay and the Super Badass Distortion.
