Creepy Fingers Effects is a boutique guitar pedal company based in Southern California, founded by Brad Davis, the bassist of stoner rock band Fu Manchu. Davis began selling his first Sugarboost units to friends in 2007 and officially launched the brand in 2008. Pedals are built in small batches and assembled by hand, often using NOS (new old stock) components and housed in powdercoated, silkscreened metalflake enclosures.

The lineup leans heavily on vintage-flavored fuzz and boost circuits, with models including the Fuzzbud, Blacklight Fuzz, Crazy Creepy, Fuzzfreak, Brummie, The Balch, Creepyface, and the Sugarboost clean boost. The aesthetic and circuit choices reflect Davis's background in heavy riff-based rock, and the pedals are commonly associated with fuzz, stoner, and garage tones. Units are sold direct through the brand's Big Cartel store and through a small network of boutique dealers such as Cottonwood Music Emporium, Coast Sonic, and Reverb.

Creepy Fingers has 6 products cataloged on Equipboard, including Fuzz Effects Pedals, Boost Effects Pedals, and Overdrive Effects Pedals. Their gear is featured by 2 artists, with the strongest followings in Rock and Folk, World, & Country. Notable users include Neil Young and Blake Mills.
