Electrofoods Ultd is a boutique effects pedal company based in Philadelphia, Pennsylvania, building hand-made analog stompboxes in small batches. The operation is run by Mattie and Carl, who assemble and bias each pedal individually, and the brand emphasizes lifetime free repairs on its products.

The lineup leans toward gain effects with idiosyncratic names and circuits. Core pedals include the Germ Warfare, a Soviet-germanium-transistor boost with active treble and mids controls; the Rad Sickness, a silicon-based low-gain drive and boost sibling to the Germ Warfare; the Nepenthes, an op-amp distortion with switchable Bright and Thick voicings; and others such as the Eye of Ra, Pigpile, Lil Pig, and Oprichniki. Collaborative releases include the RBMK, co-designed with Evan Craig of Dirge Electronics, as well as the Colon Exploder and Kerria Lacca.

Alongside the product work, Electrofoods Ultd has used its platform to voice support for underrepresented groups in the music community and for other small pedal builders, positioning itself within the cottage-industry end of the effects market rather than the mass-production tier.

Electrofoods Ultd has 4 products cataloged on Equipboard, including Overdrive Effects Pedals, Boost Effects Pedals, and Distortion Effects Pedals. Their gear is featured by 1 artist, with the strongest followings in Rock. Notable users include Jake Beitel.
