IdiotBox Effects is a one-person guitar and bass pedal builder operated by Matt Shea out of Texas, founded in 2011 after Shea left a career in accounting to build effects full time. He designs the circuits, draws the graphics, and screen prints the enclosures himself, with the brand leaning heavily on pop culture nostalgia — Star Wars, retro video games, horror films, and other vintage nerd-culture references — for both pedal names and artwork.

The lineup spans fuzz, distortion, overdrive, delay, modulation, and noise boxes, alongside dedicated bass pedals. Signature designs include the No Moon, a Death Star-themed mega-pedal combining Big Muff, Tube Screamer, and RAT-style circuits in a single enclosure, the Blower Box Deluxe gated fuzz, the Ron Fucking Swanson Super Fuzz, and the Dungeon Master. The brand also produces small runs of band-themed and artist collaboration pedals.

IdiotBox sits in the boutique stompbox niche, with distribution through dealers like Coast Sonic, Guitar Center, and Reverb, and a reputation for oddball, aggressive, and visually distinctive pedals rather than transparent or studio-polished circuits.

Idiot Box has 2 products cataloged on Equipboard, including Tremolo Effects Pedals and Fuzz Effects Pedals. Their gear is featured by 1 artist, with the strongest followings in Rock. Notable users include Scott Shriner.
