Stomp Under Foot is a boutique effects pedal company founded in 2008 by Matt Pasquerella, originally based in Massachusetts and later relocated to Florida. The company has earned a reputation as one of the foremost builders of Big Muff-style fuzz pedals, with every unit handmade and hand-wired using new-old-stock (NOS) through-hole components to faithfully capture the character of vintage originals. Pasquerella's deep expertise in classic fuzz circuits — honed through years of collecting and studying vintage Big Muff variants — has made Stomp Under Foot a go-to name among fuzz enthusiasts.

The lineup is anchored by meticulous recreations of iconic Big Muff eras. The Ram's Head, Civil War, and Tri-Muff are among the company's signature models, all registered trademarks of the brand. Other notable pedals include the Green Russian, Pumpkin Pi, Violet Menace, Civil Unrest, Red Menace, Sonic Generator, Dirt Preacher, Skinner Box, The Pi, and the Demogorgon. Beyond Muff variants, Stomp Under Foot also produces pedals inspired by other classic circuits, including Fuzz Face-style designs like the Hellephant and Tone Bender-inspired builds like the Supa Dirty Rooster. Pasquerella is widely regarded as one of the leading proponents of the Muff sound in the boutique pedal world, alongside builders from Skreddy Pedals, Wren and Cuff, and Vick Audio.
