About Electro Harmonix.

Electro Harmonix is one of those legendary companies that has managed to maintain a strong presence in the market since 1968, when guru Mike Matthews founded the brand in New York City.

Mike balanced his work between the IBM computer company and his home garage, where he built pedals for many years. His first creation was the LPB-1, a very simple booster-line driver that quickly gained fame.

In the early 1980s, Electro Harmonix was forced to close due to the influx of Asian companies flooding the musical instrument market, such as Roland/Boss, Ibanez, and Tokai. Fortunately, the company made a comeback a few years ago by reissuing its classic designs in a new phase under the name New Sensor, as renamed by Mike.

From the beginning, the factory specialized in effects pedals, attracting major music figures like Carlos Santana, Kurt Cobain (Nirvana), Jonny Greenwood (Radiohead), Jimi Hendrix, Robert Fripp (King Crimson), Billy Corgan (The Smashing Pumpkins), Jack White (The White Stripes), John Frusciante (Red Hot Chili Peppers), The Edge (U2), Cliff Burton (Metallica), David Gilmour (Pink Floyd), and Alex Turner (Arctic Monkeys).
