Electro-Harmonix (EHX) is one of the most influential names in the history of guitar effects. Founded in 1968 in New York City by Mike Matthews, the company became the first to offer professional-quality guitar effects pedals at prices that made groundbreaking sounds accessible to musicians everywhere.

Over the decades, Electro-Harmonix has introduced some of the most iconic effects ever created, including the legendary Big Muff Pi, Deluxe Memory Man, POG, Soul Food, Small Clone and Electric Mistress. These pedals have shaped the sound of countless artists across rock, blues, alternative, indie, metal and experimental music.

Beyond guitar pedals, EHX also manufactures guitar amplifiers, vacuum tubes, professional audio components and amplifier parts. The company owns the world's largest vacuum tube factory, producing premium tubes renowned for their exceptional reliability, high fidelity and performance in guitar amplifiers, Hi-Fi systems and professional audio equipment.

Driven by a passion for innovation and musical creativity, Electro-Harmonix continues to develop products that inspire musicians to explore new sounds while maintaining the quality, originality and reliability that have defined the brand for more than five decades.
