Kurt Cobain’s Electro-Harmonix Big Muff Pi
According to Butch Vig, who produced ‘Nevermind’, Kurt used this pedal on ‘Lithium’. However, it is important to notice that whenever he played live, he would either use a Boss DS-1 or a DS-2 distortion pedal instead.
We used an Electro- Harmonix Big Muff fuzz box through a Fender Bassman on ‘Lithium’ to get that thumpier, darker sound. [Nirvana: Super Fuzz Big Muff]
