Electro-Harmonix: 50 Years of Innovation in the Service of Sound
Founded in 1968 by Mike Matthews on the streets of New York, Electro-Harmonix is much more than just an effects pedal manufacturer: it is an institution. The brand with its unmistakable logo literally invented the guitar and bass effects market as we know it today. From the first LPB-1 booster sold out of the back of a music store to the ultra-sophisticated digital pedals of the current lineup, EHX has never stopped innovating, surprising, and inspiring generations of musicians.
What sets Electro-Harmonix apart from other manufacturers? A unique philosophy driven by its iconic founder: never follow the rules. As Mike Matthews likes to say, "following the rules may keep you out of trouble, but nothing truly great was ever created by following the rules." This iconoclastic approach has given rise to some of the most revered pedals in music history.

The History of Electro-Harmonix: From New York to the World
It all started in 1968 when Mike Matthews, a young entrepreneur passionate about electronics, created the LPB-1 (Linear Power Booster), a small pedal designed to give more punch to the guitar signal. The success was immediate and laid the foundation for what would become one of the biggest names in the music industry.
The 1970s were a period of creative ferment for EHX. It was during this decade that the pedals that would become legendary were born: the Big Muff Pi (1969), the Small Stone (1974), the Electric Mistress (1976), the Memory Man (1976), and the Clone Theory (1977). Each of these creations brought a unique sonic color that has had a lasting influence on rock, funk, jazz, and beyond.
After financial difficulties in the 1980s that led to a temporary bankruptcy, Mike Matthews bought back the brand in the early 1990s and orchestrated a triumphant return. The reissue of classics, combined with new innovations, allowed EHX to reclaim its place at the top. Today, Electro-Harmonix still designs and manufactures its pedals in New York, perpetuating a tradition of excellence and artisanal craftsmanship.

The Iconic Pedals That Changed Music
The Big Muff Pi: The Ultimate Distortion Sound
It is impossible to talk about Electro-Harmonix without mentioning the Big Muff Pi. Created in 1969, this fuzz/distortion pedal has become one of the absolute benchmarks of the genre. Its infinite sustain and creamy saturation have won over artists as diverse as David Gilmour (Pink Floyd), Jack White (The White Stripes), J Mascis (Dinosaur Jr.), and Dan Auerbach (The Black Keys).
The Big Muff has seen many variations over the decades: Ram's Head, Russian, Triangle, Op-Amp, Tone Wicker... Each version brings its own sonic signature while retaining the unmistakable DNA of the Big Muff family. The Big Muff range remains one of the most sought-after on both the used and new markets today.

The Memory Man: The Analog Delay Revolution
Launched in 1976, the Memory Man is the first analog delay to use BBD (Bucket Brigade Device) chips to deliver substantial delay time in a compact format. Its warm, organic sound, lush modulations, and famous chorus mode have made it an indispensable tool for generations of guitarists.
The Deluxe Memory Man, its enhanced version, is considered by many to be the best analog delay ever created. It continues to be manufactured today, proof of the timeless relevance of this design. Fans of analog sound can explore the different versions of the Memory Man available on the market.
Small Stone, Electric Mistress, and Other Essentials
Beyond distortion and delay, EHX has left its mark on history with its modulation effects. The Small Stone (1974) is one of the most copied and beloved phase shifters in the world. The Electric Mistress (1976), with its unique flanger and matrix filter, defined the sound of many cult recordings, notably those of The Police and David Gilmour.
The POG (Polyphonic Octave Generator), launched in the 2000s, created an entirely new category of effects by allowing multiple octaves to be generated simultaneously from a monophonic signal. This pedal has become a standard on pedalboards around the world.

The Current Lineup: Between Tradition and Innovation
Electro-Harmonix today offers a rich catalog of over 100 models, divided into several families to meet the needs of all musicians, from beginners to the most demanding professionals.
The Pico Series: Power in Miniature Format
The Pico range represents the ultimate in miniaturization at EHX. These ultra-compact pedals integrate complex algorithms into a tiny enclosure, with no compromise on sound quality. Among the flagship models: the Pico Shimmer (cosmic reverb), the Pico Intelligent Harmony Machine (intelligent harmonization), and the Pico Deep Freeze (infinite sustain).
The 9 Series: Emulation in the Service of Creativity
The 9 Series pedals embody EHX's philosophy of innovation: transform your guitar into a completely different instrument. The B9 (organ), C9 (classic organ), Mel9 (mellotron), Synth9 (synthesizer), and Bass9 (bass) use advanced modeling technology to faithfully reproduce the sound of these instruments. These pedals have become essentials for guitarists looking to expand their sonic palette.
Deluxe Editions and Reissues
EHX continues to evolve its classics with Deluxe versions offering more control and flexibility. The Deluxe Bass Big Muff Pi 2, the Deluxe Memory Boy, and the Deluxe Electric Mistress XO combine the legendary sound of the originals with modern features like soft-touch footswitches, parametric EQs, and effects loops.
At the same time, the brand offers faithful reissues of its most sought-after vintage models, such as the Ram's Head Big Muff Pi or the Op-Amp Big Muff, allowing guitarists to access these legendary sounds without breaking the bank on the collector's market.
Artists Who Trust EHX
The list of musicians using Electro-Harmonix pedals is a veritable who's who of modern music. Jack White never takes the stage without his Big Muff. David Gilmour built part of his legendary sound around the Electric Mistress and the Deluxe Memory Man. Peter Hook (Joy Division, New Order) used the Clone Theory to sculpt his signature bass lines.
More recently, artists such as Yvette Young (Covet), Bill Kelliher (Mastodon), and Sarah Lipstate (Noveller) incorporate EHX pedals into their setups, proof that the brand continues to inspire new generations. The scope of application extends far beyond guitar: bassists, keyboardists, and even singers use EHX vocal processors like the V256 Vocoder.
