The Electro-Harmonix Big Muff fuzz pedal has seen many variations through the years, and the army-green Russian Big Muff has always been a favorite. Its particularly grungy sound has made it a huge hit with rock guitarists, as well as many bassists, and has made it one of the more sought-after vintage pedals today. All of the original magic is back with EHX's reissue of this classic pedal. And Electro-Harmonix put all the gritty power into an enclosure that will fit comfortably on any pedalboard. Plug in, switch it on, and stand back.
