Founded in 2008 by Joe Vella and Eric Kessel, Electro-Faustus is a Patchogue, New York-based maker of handmade experimental noise devices, effects pedals, and unconventional electronic instruments. The company began when the two friends decided on a whim to sell a few oscillators, and has since grown into a recognized name in the noise and experimental music world. Their product line includes the EF103 Guitar Disruptor (a hybrid overdrive/octave/oscillation pedal), the EF102 Photo Theremin, the EF110 Blackfly metallic swarm generator, the EF109 Drone Thing, the EF112 Astral Whip, the EF116 Infektor, the Drone King, and the Theremorph, among others. They also offer Eurorack modules such as the Blackfly Modular.

Electro-Faustus occupies a distinct niche in the effects pedal market, eschewing traditional tone-shaping in favor of instruments designed to generate, manipulate, and embrace noise. Their devices are built for everyone from bedroom experimenters to touring professionals, and can function as standalone instruments or integrate into existing rigs. Notable artists who use Electro-Faustus gear include Merzbow, Robin Finck of Nine Inch Nails, Vernon Reid of Living Colour, and Sofia Hultquist (Drum & Lace). The company's ethos is captured by the Luigi Russolo quote featured on their website: "We must replace the limited variety of orchestral instruments by the infinite timbres of noises obtained through special mechanisms."

Electro-Faustus has 17 products cataloged on Equipboard, including Guitar Synth Pedals, Multi Effects Pedals, and Tabletop Synthesizers. Their gear is featured by 9 artists, with the strongest followings in Rock, Blues, and Electronic. Notable users include Merzbow, Denver Dalley, and Andy Summers.
