Electro Harmonix Germanium 4 Big Muff Pi Overdrive Pedal


Electro Harmonix Germanium 4 Big Muff Pi Pedal

Combining four classic germanium transistors, the Germanium Big Muff Pi is the result of a focused modern design dripping with EH analog heritage. An independent overdrive and distortion each have their own sets of two germanium transistors as well as independent controls. The ability to stack and use both the overdrive and distortion together delivers the power of a four germanium transistor circuit with ultimate control flexibility.


  • "During a recent recording session, I shared the Germanium 4 with a couple of other guitarists who use a variety of name-brand and boutique distortion and overdrive pedals, and they were very impressed. One guitarist commented that the Germanium 4 had a ton of headroom and seemed capable of getting a 'really incisive, steely fuzz.'"
  • "I've owned a number of Big Muff pedals over the decades, and this is easily one of my favorites. It offers plenty of gain, but it's capable of a wide range of distorted timbres-not just an overly buzzy one."
  • "If you're looking for classic distortion and fuzz tones, with an additional overdrive circuit thrown in, for less than a C-note, the Germanium 4 Big Muff Pi is a no-brainer. Pros: Low price. Sounds great. Two effects in one. Plenty of headroom. Cons: None."
