Electro-Harmonix Deluxe Big Muff Pi Distortion / Sustainer Pedal


The Electro-Harmonix Deluxe Big Muff Pi is an expanded, highly-tweakable version of the classic Pi fuzz. Taking the ubiquitous sound of the standard Big Muff and adding a whole new world of control, the Deluxe Big Muff Pi goes where vintage Muffs simply cannot. A sweepable mid-shift EQ with separate switch lets you stomp into cutting tones for solo sections, offering a different texture from your standard sound. You can even plug in an expression pedal to control the center frequency and get a moving filter happening on the fly. An attack control brings clarity back to your sound, even at extreme gain levels. Little too much noise in your signal? Bring the onboard gate to the party and tame it with ease. Also switchable on the Deluxe Big Muff Pi are a fixed bass boost and a high/low gain setting, making this version of the Muff the most versatile yet.

    There is nothing new to say about Big Muff. Everyone use it, everyone love it, the famous use it, the non-famous use it. So if you want to go classical this is your perfect pedal. In my case I will take the risk to go in an unexplored fields with modern fuzzes even when I have this old faithful. But…

    Verified Purchase

    Fuzziest pedal that I own and very versatile. Combine it with an EHX Holy Grail and an expression pedal to make some haunting lead solos. No cons so far. I like it.

  • Great if you want to experiment

    There's so much talk about the different big muff variations, this offers a chance to get a pretty close approximation of the real deals. Even if you don't care about making it sound like a Russian or Rams, the mids section can really help with using this in a chain, something I find the big muff does not do well
