Even if you're not a guitar nerd, you know what Electro-Harmonix's Big Muff guitar pedal sounds like. Since 1969 it has been the dirty fuzz coating for countless guitar solos and backing tracks on songs by everyone from Santana to Dinosaur Jr. Today, Electro-Harmonix hand-assembles and tests 75 different effects pedals in its New York headquarters.
This is also where the company's perpetually innovative effects are designed. Premier Guitar got a guided tour of the facility from EHX founder Mike Matthews. [Electro-Harmonix]
