Description
The Electro-Harmonix Big Muff Pi is more than just a guitar pedal, it's a piece of music history. This classic fuzz effects pedal has been the secret weapon of legends like Jimi Hendrix and Santana, as well as contemporary artists from Jack White to Muse. Its rich, creamy distortion and violin-like sustain have been shaping the sound of rock music for the better part of 30 years.
Just like the original '70s Big Muff Pi, this reissue features three intuitive controls—Volume, Tone, and Sustain—that let you dial in a wide range of distortion styles. Crank the Volume for a boost to cut through the mix, increase the Sustain for endless sustain and harmonics, and sweep the Tone from a warm, bassy purr to a sharp, trebly bite. With just a few tweaks, you can achieve the signature Big Muff Pi sound or forge your own.
Despite its roots in rock's golden age, the Big Muff Pi is not just a relic. It's a workhorse pedal built for today's players. Its compact, rugged enclosure can withstand the rigors of the road, and it can be powered with a 9V battery or any standard 9V DC power adapter.
Key Features:
- Volume, Tone, and Sustain controls for a wide range of distortion styles
- Rich, creamy distortion and violin-like sustain
- Compact, rugged enclosure suitable for touring
- Can be powered with a 9V battery or any standard 9V DC power adapter
- Used by legendary and contemporary artists alike
- Made in the USA

Equipboard's Expert Review
Equipboard tested this
The Fuzz Legend Lives OnIconic tone, simple yet effective
In our tests, we found that the Electro-Harmonix Big Muff Pi lives up to its legendary status. This classic fuzz pedal has been a staple in countless pedalboards for decades, and it's easy to see why.
Upon unboxing, we were immediately struck by its iconic design and sturdy construction. The large enclosure may not be ideal for cramped pedalboards, but it certainly feels built to last. The simple three-knob layout is intuitive and inviting, allowing us to dial in our desired tone quickly.
We were impressed by the Big Muff's versatility across different genres. From searing lead tones to thick, woolly rhythm sounds, this pedal delivers the goods. The sustain is phenomenal, and the distortion control offers a wide range of fuzz textures. We particularly enjoyed how well it paired with both clean and dirty amp channels.
However, it's not without its quirks. In our experience, the Big Muff can sometimes sound a bit too bassy or muddy, especially in a band mix. We found ourselves wishing for more midrange presence to help cut through. Additionally, we noticed some noise issues when using certain power supplies, so it's worth experimenting to find the right setup.
For us, the Big Muff Pi remains a must-have for any guitarist seeking that classic "wall of sound" fuzz tone. It's perfect for players who prioritize raw, powerful sound over intricate tweakability. However, those with limited pedalboard space or those seeking a more modern, precise fuzz might want to look elsewhere. Nonetheless, at its price point, it's hard to beat the Big Muff's combination of iconic tone and rugged reliability.

Owner Insights
We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about Electro-Harmonix Big Muff Pi.
Use cases and applications
-
The Big Muff Pi is praised for its sustain and melodic lead tones but isn't ideal for fast rhythm in metal genres like Megadeth or Metallica.
Source -
Overdrives can enhance the Big Muff's EQ control, helping to refine the pedal's fuzz-heavy output for different musical genres.
Source -
For those interested in clear chord articulation, the Violet Ram’s Head variant is suggested for its aggressive and clearer sound profile.
Source
Comparisons
-
For achieving thrash metal tones on a budget, consider the Joyo "Pocket Metal," designed for a sharp, tight sound akin to "Rust in Peace."
Source -
The Boss DS-2 is noted for having excessive fuzz for metal, whereas the DS-1 combined with an EQ provides better results.
Source -
The OpAmp Nano Muff offers a more modern, scooped, and saturated sound compared to the standard Nano, which could appeal to those seeking a contemporary Muff tone.
Source -
The Ram's Head is frequently recommended for achieving a Gilmour-like tone, while the Russian variant is noted for its uniquely bass-heavy, smooth sound.
Source
Features and functionality
-
The Big Muff tends to get "flumpy" with speed picking, requiring careful manipulation of its sound settings.
Source -
The Nano version tends to sound boxier with less top-end than the USA big box, making it less vibrant for some users.
Source -
The Sovtek Deluxe Big Muff Pi includes a midrange footswitch, critical for enhancing mids that can be lacking in typical Muff pedals.
Source -
The Way Huge Swollen Pickle Fuzz MkII, inspired by the Green Russian Muff, offers five external knobs and two hidden mini knobs for precise tonal control.
Source
Build quality
-
The original Big Muff Pi's circuit occupies a small space in its large enclosure, allowing for a much more compact design in the Nano version.
Source
Setup and maintenance
-
Older big-box Muffs require a 3.5mm adapter for power, but newer models come with a standard Boss power jack, simplifying integration into modern pedalboards.

Nothing quite like it!
This is one of my favorite pedals and for good reason, this is the thickest mix cutting pedal I have heard. As someone who grew up listening to Smashing Pumpkins I always strived for that sound and when I found the Big Muff I couldn't go back. I use this in my recordings usually for when I need a thick wall of noise or a screaming guitar lead/solo. This thing is HARD to control but I love it for that, it has a niche but it fills it the best way possible I feel. Worth the money go get it!

classic, built like a tank
is that sound, everyone knows, the big muff, that ol´ mid scooped fuzz sound.
practically impossibe to break, a good pedal, does it well on so many genres, huge fuzz.
but being honest, the size dont make sense anymore, the circuit board is a half of the size of the box, not so practical for pedalboards and gigging (plus it is hard to have it cutting in the mix due to the lack of mids).
that was my first pedal but im getting rid of it because i dont like the lack of mids for live sound and the impossibility to generate it with the tone or sustain knob. plus it can get very fizzy if you crank some knobs. and i need more sonic destruction.
i love the pedal, probably muff styled fuzz´s are my favorite pedal ever, but they need mods to make it work.
Preferred Settings + Usage:
pretty low sustain and dark tone (about 10). for getting that doomy cracked up shoegaze sound. always neck pickup
903
Same for me on the 'sustain' setting, I keep mine dialed in pretty low as well. I wanted a "real fuzz" sound so I dumped the tone down pretty low, turned the 'volume' up, and run it through an Orange OR15 with a fair amount of gain dialed in. The sound is pretty much what I was looking for, and surprisingly it still plays really reactive and fast on the higher strings, but gives me that nice fuzzy, smooth sound on the lower strings. Especially with the neck pickup of a guitar engaged. Classic pedal, sustain for days.

Classic and fantastic
The basic NYC big muff its great because its original sounds can still sound incredible on todays music. I would recommend that every musician (and person if you ask me twice) try one out as it can be used on almost anything. Especially if you want to try new sounds in your productions, drums bus distortion is a must. There are thousands of muffs but the og is still one of the greatest
Preferred Settings + Usage:
Tone low its the stoner express

"I’m playing the Rockerverb and I have an **Electro-Harmonix Big Muff*, a standard BOSS overdrive, digital delay, chorus… I mean, I like to mess around with Micro Synths and the Line 6 digital delay pedal. That’s fun."
when asked "Tell us about your pedal rig – it looks like you’re using some kind of big multi-effect – am I right?" he says: "Yeah a POD hd500x. It’s got lots of goodies in it. Sounds good. I’ve got a lot of the real pedals that it’s emulating and I’ve A-B’d them and I can’t tell the difference. Like the Big Muff is exactly the same as the real thing except it has better eq in the POD."
Benjamin Booker can be seen adjusting the Big Muff on his pedalboard at 5:10 in this performance of "Have You Seen My Son?"
In this collection of pedals photo posted by Ekstrom on his Instagram profile, the EHX Big Muff Pi can be seen.
At 1:37 you can see part of a huge pedal sticking out and this is clearly a big muff.
During the Busse Woods tour, Lori S. was seen using the Electro-Harmonix Big Muff Pi fuzz effects pedal, as evidenced in the Imgur photo.
:20 clearly the signature big muff at the bottom of the screen with it looks like a boss tuner and maybe another boss distortion?
