Description
Unveiling the Electro-Harmonix Little Big Muff Pi - the classic fuzz pedal that's been condensed into a compact, rugged die-cast box without compromising its iconic sound. This compact fuzz pedal delivers the same full-bodied, silky smooth, violin-like sustain that the 1970 original Big Muff Pi is known for. It's the perfect pedal to have at your disposal when you want to sustain a note for an entire set, without sacrificing pedalboard space.
The Little Big Muff Pi is straightforward and easy to use, featuring the same 3-knob setup as its predecessor - Sustain, Tone, and Volume. Dial up the Sustain for a supple, violin-like sustain that's ideal for lead playing, or crank out power chords for a wall of enveloping fuzz, thanks to its massive bass response. The tone control provides ample room to adjust the sound, allowing you to cut through when needed. And while it excels at extreme settings, dialing down the Sustain and rolling off your volume control will reveal a treasure trove of low-to-medium-gain tones waiting to be discovered.
Key Features:
- Delivers the iconic tones of the classic Big Muff Pi in a compact, pedalboard-friendly enclosure
- Versatile 3-knob setup - Sustain, Tone, Volume
- Offers violin-like sustain and a massive bass response
- Tone control gives you plenty of room to adjust your sound
- True bypass design keeps your signal clear and pristine when the pedal is not in use
- Housed in a rugged, heavy-duty die-cast enclosure
- Ideal for various settings, from extreme to low-to-medium-gain tones.

It's a Big Muff
It does the thing you expect a muff to do. It's quite noisy when you crank it and the footswitch will inevitably break like all EHX pedals but that's a 2 dollar fix. I love a muff.

A classic
I use it in parallel with the clean bass signal and I love the sound it produces, to say the least, it's a bit big for my pedalboard.
249
Really really fun but kinda noisy.
I get it, it is supposed to be noisy, but if you don't have a Noise Gate pedal, this will be your nightmare when you aren't playing anything and the pedal is on. Other than that, it is pretty damn fun and wouldn't change it for anything lmao.

Amazing sound
Great sound and versatility; make sure to play with the tone and sustain knobs for different sounds

Classic Fuzz/Distortion sound
The bigg muff is a classic pedal and gives you a amazing distorted-fuzzy style, you can use it to create both a dry fuzzed sound or a ripped of distortion sound, and of course, the middle term. Besides that, he's very useful in solos and rhythm sections. Amazing pedal!

The Sound of the '70s
I didn't think I needed one of these and now I don't know how I could ever play without one. I started using it when covering Sabbath songs and now it gets used on all sorts of rock. This is such an affordable and tine tested fuzz. The Boutique ones may be amazing as well but this is what your hearing on all your favorite stoner metal albums anyway and its half the price

Wonderful fuzz pedal.
I've always been a huuuge fan of fuzz pedals. I'm also a fan of EHX's design and sound in general. So this was a great addition to my arsenal and pairing it with a nice blues overdrive makes this pedal an absolute beast.

Pair with a light overdrive
At first I wasn't so keen and thought it sounded perhaps a little scooped and weak, but when paired with the MXR Custom Badass Mod OD on a very low gain setting to boost the mid, the whole "scooped" feel went away. Now it sounds much more full and more powerful whilst retaining its classic muff tone.
Makes strange noises. Perfect!
Is there any need to talk about what this pedal does? It's a Fuzz, a very tough one, it makes your guitar sound like the strings are on high voltage. Great solo sound, you actually can use it for rhythm, too, but NEVER play more than two strings at a time.
very cool

Not tried it, but from sound demos it sounds very similar and as far as I’m aware it is a clone.
