Be sure to catch John Frusciante's comments on the English Muff'n in the April 2009 issue of Vintage Guitar Magazine: "The Electro-Harmonix English Muff'n tube fuzz has some really extreme EQ and a big, thick and meaty sound. I used it on the solo for 'Enough Of Me.' I turn the EQ up, but leave my guitar tone knobs down and use either the middle or neck pickup so the original source sound is really dark and plain. If you blast the tone controls on the effect, you get a really thick, beautiful sound that reminds me of an exaggerated Eric Clapton tone in cream, where you have this really smooth fuzz."

In addition to the English Muff'n, John has also toured and recorded with the Micro Synthesizer, Big Muff Pi (both USA and Russian), POG, Metal Muff, HOG, Holy Grail, and Deluxe Electric Mistress. That said, I'm sure you fru-heads are still going to email and tell me what I left out.

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.
