Little Big Muff Pi

Distortion/Sustainer
Same silky smooth violin-like sustain and creamy tone that made the legendary 1970 Big Muff Pi famous. This little brother displays its heritage proudly. Same circuitry in a compact die-cast box.

Mike Matthews in “Fuzz” Documentary
Posted 8/29/2008
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.

EHX Strings
We've been playing these EHX Strings ever since we first took them home to try them out, back in 2002.

We find them to consistently offer rich harmonics with powerful definition, while also lasting longer and staying in tune longer than conventional strings.

We use them, we like them, and we think you will too. Available in 9's, 10's, 11's.
