Open Big Muff is inspired by the classic Electro-Harmonix Big Muff Pi(*). This massive pedal has defined the sound of rock guitar! Throughout the late 1960s and early 1970s the fuzz revolution took place spicing up rock and roll music. The Electro-Harmonix Big Muff Pi* was one of its greatest representatives. Its rich tone and creamy, violin-like sustain made its name among legends of all times and styles - from Hendrix and Pink Floyd, to Sonic Youth and the White Stripes.
