Description
Electro-Harmonix (EHX) is an American guitar effects pedal manufacturer founded by Mike Matthews in 1968 in New York City, recognized as a pioneer in affordable, innovative stompbox design. Its iconic products include the Big Muff Pi fuzz, Memory Man delay, Small Stone phaser, and Electric Mistress flanger, which have shaped the sound of artists from Jimi Hendrix to David Gilmour. After a bankruptcy-driven closure in 1984, the brand was revived in the 1990s and remains an active, leading manufacturer of effects pedals, guitar amplifiers, and vacuum tubes.
