Electro-Harmonix

Electro-Harmonix was founded in 1968 by a young New Yorker fresh out of Cornell University who combined his passions for music and business to create a niche in the nascent world of rock ‘n’ roll. With a first product dubbed the LPB-1, short for Linear Power Booster, Mike Matthews helped usher in the age of overdrive. EHX’s most iconic pedal, the Big Muff Pi distortion/sustainer, was introduced in 1969. Its sound and appeal are so powerful that it’s been imitated and copied by almost every pedal company on the planet. Currently, Electro-Harmonix has a product line of well over 150 pedals ranging from the essential to the exotic. Along the way there have been many firsts. These include the Electric Mistress, the first low cost flanger; the Memory Man, the first analog delay; the 16 Second Delay, the first looper pedal; and the Instant Replay, the first low cost sampler. More recently products like the POG Polyphonic Octave Generator, the Freeze Sound Retainer and the “9” Series, i.e. B9, C9, Key9, Mel9 and Synth9 keyboard emulators, demonstrate that EHX’s legacy of sonic innovation is unique. Electro-Harmonix brings players imaginative products that fan the flames of creativity at prices a working musician can afford.
