Every few years, a pedal comes along that reminds us why we fell in love with effects in the first place. The Electro-Harmonix Big Muff Pi 2 and Bass Big Muff Pi 2 are exactly that kind of release. They feel modern, compact, and packed with history. But to understand why these new versions matter, you have to look back at where the Big Muff came from and how a collaboration with JHS Pedals helped reshape one of the most iconic fuzz circuits ever made.
How the Big Muff Became a Legend
The original Big Muff Pi arrived in the early 1970s, and it did not take long for it to become a staple on pedalboards everywhere. Thick fuzz, endless sustain, and a tone that could be smooth or snarling depending on how you pushed it made it unlike anything players had heard before.
Over the decades, the Muff evolved in ways that were sometimes intentional and sometimes the result of whatever parts were available at the time. That is how we ended up with the famous eras players still chase today:
- Triangle: bright, open, and articulate
- Ram’s Head: smoother, more scooped, famously used by Gilmour
- Op-Amp: aggressive, mid-forward, and perfect for big rock riffs
- Russian: wooly, thick, and beloved by bassists and doom players
Each version had its own quirks, and no two vintage units were exactly alike. That inconsistency became part of the charm and part of the frustration for players trying to find the perfect one.
Enter JHS Pedals: A Collaboration Built on Obsession
If there is anyone who knows the Big Muff inside and out, it is Josh Scott from JHS Pedals. His Muff Museum is a real thing, filled with hundreds of variants that he has cataloged and studied. When Electro-Harmonix teamed up with JHS, it was not just a co-branding exercise. It was a chance to take decades of Muff history, identify the circuits players love most, and bring them together in a single, reliable pedal.
From our perspective, this collaboration makes perfect sense. Electro-Harmonix has the legacy. JHS has the deep circuit knowledge. Together they created something that feels both classic and fresh.
What Makes the Big Muff Pi 2 Different
The Big Muff Pi 2 takes four of the most iconic Muff circuits and puts them into one compact enclosure. You still get the familiar Volume, Tone, and Sustain layout, but now you can flip between four distinct voices that each capture a different era of the Muff’s evolution.
It is not a greatest hits list. It is more like a curated museum exhibit you can actually play through. And because these circuits were selected and refined with JHS, they feel intentional rather than approximate.
For guitarists, this means you can move from early seventies clarity to nineties Russian grit without swapping pedals or hunting down rare originals.
The Bass Big Muff Pi 2: Built for Low End
Bassists have always had a complicated relationship with the Big Muff. The fuzz is incredible, but the mid-scoop of many versions can make bass disappear in a mix. The Bass Big Muff Pi 2 solves that with a set of modes tailored specifically for low-frequency clarity and punch.
You also get:
- A Blend control to keep your clean tone present
- A Crossover switch for added definition
- Four bass-friendly Muff circuits that preserve low end
We have tried a lot of bass fuzzes over the years, and this one feels like a thoughtful evolution rather than a guitar pedal with the word bass printed on it.
How the Pi 2 Models Compare to the Originals
Here is where the story really comes together.
Multiple Eras in One Box
Vintage Muffs were single-flavor pedals. The Pi 2 gives you four distinct circuits without needing four pedals.
Consistency You Can Count On
Original Muffs vary wildly, even two from the same year can sound different. The Pi 2 models give you reliable, repeatable versions of those classic tones.
Modern Size and Modern Reliability
The classic Big Muff enclosure is iconic and large. The Pi 2 pedals fit comfortably on modern boards.
Bass-Specific Engineering
The Bass Pi 2 is not an afterthought. It is purpose-built for clarity, punch, and mix-friendly fuzz.
A First-Time Muff Collaboration
This is the first time Electro-Harmonix has partnered with another pedal company to define the sound of a Muff. That alone makes the Pi 2 series a milestone.
Why These Pedals Matter Right Now
The Big Muff Pi 2 and Bass Big Muff Pi 2 are not just new versions. They are a celebration of everything that made the Muff iconic in the first place. They give players access to decades of fuzz history without the guesswork, the collector prices, or the pedalboard real estate.
At Pixel Pro Audio, we love gear that respects the past while pushing things forward. These pedals do exactly that. They are familiar, flexible, and genuinely fun to play, whether you are chasing vintage tones or carving out something new.
