The MXR Distortion + was designed in the early '70s and has since found its way onto many great players' pedalboards the world over, such as Randy Roads and Bob Mould. Though it's named the "+," this pedal doesn't go too far on the distortion - it can be turned down low enough to register as a subtle, low-volume overdrive. That's not to say you can't get crazy distortion from this pedal; you can get ferocious fuzz just by cranking the Output and Distortion knobs as far as possible. The MXR Distortion + is simply a versatile, intuitive tool for creating a wide range of tones.
