The '''MXR Distortion +''' ("Distortion Plus") is a [[distortion (music)|distortion]] pedal originally designed in the 1970s by [[MXR]] Innovations. As its name implies "[[distortion]]," it's a 'distortion' (parallel clipping) but has a rather mild sound. It has been cloned many times, most famously by the DOD 250 Overdrive (a distortion). The pedal uses a single op-amp and a pair of [[germanium diode]]s to ground (parallel-push) for clipping in a very simple configuration with only Output and Distortion controls, no tone control; the pedal uses no discrete [[transistors]].  Turning up the Distortion control increases the amount of distortion and at the same time cuts some bass from the signal.  This pedal is perhaps best known for its crunchy [[heavy metal music|heavy metal]] sound that was featured by [[Randy Rhoads]] in his work with [[Ozzy Osbourne]].  Jerry Garcia of the [[Grateful Dead]] used this pedal exclusively for distortion in the late 1970s.  [[Bob Mould]] of [[Hüsker Dü]] also used the Distortion + as part of his trademark guitar sound. [[Dave Murray (musician)|Dave Murray]] of [[Iron Maiden]] has used Distortion + since the early 1980s. [[Thom Yorke]] of [[Radiohead]] has included the + for many of his signature distortion sounds, using a variety of guitars to achieve various tonal options.
