Check out this fantastic Big Muff anime from the incredibly talented Japanese artist Nota.

Anthropomorphism, the attribution of human characteristics to an object, is highly prevalent in Japan with mascots giving living, often human form, to everything from fast food to computers.

While we can't say these are official Big Muff mascots or even the characters we imagine when we think about the various versions of the beloved Big Muff, there's no disputing the high level of creativity that Nota used when designing these imaginative beings.

Here’s an easy way to get a sound reminiscent of the Smashing Pumpkins’ Siamese Dream album.

The effect chain consists of a Little Big Muff and Stereo Memory Man with Hazarai.

The Little Big Muff produces the harmonic grind while the Stereo Memory Man in the modulation mode produces a doubling and thickening of the sound.

The combination of these two effects produces a thick wall of sound using only one guitar.

The pedal settings are below:

The video below gives a quick example of the sound

A short excerpt from the documentary film "Fuzz: The Sound That Revolutionized The World" in which Electro-Harmonix founder Mike Matthews tells the story of EHX's first product, the LPB-1.

Mike also reveals the origins of "Muff," which we take care to use very sparingly: Bass Big Muff Pi, Big Muff Pi, Big Muff Pi (Russian), Double Muff, English Muff'n, Little Big Muff Pi, Metal Muff, Micro Metal Muff, Muff Overdrive, and Pocket Metal Muff (all featured in our Distortion, Fuzz, Overdrive category).

The clip also features Chris Ross (Wolfmother) and ends with J Mascis (Dinosaur Jr.) showing off his unbelievable Big Muff Pi collection.
