Utility Belt FX is a small-batch guitar effects pedal builder run by a single maker, assembling units by hand rather than through factory production. The company's flagship release is The Mutt, a dual-voice distortion pedal built around a BLEND control that mixes between a British-style crunch circuit (the "Martian" side) and a high-gain American-style distortion (the "Triple Erectifier" side), with a voice switch toggling between brighter/higher-gain and warmer/lower-gain characters. A second pedal, the Skully Fuzz, rounds out the lineup.

The Mutt was designed with Tom DeLonge's Blink-182 tones in mind — specifically the classic Marshall-into-Mesa stacked-amp sound associated with that era — but demo material shows it stretching into heavier territory including metal and djent applications. The brand has a direct-to-player orientation, selling through its own site and Reverb and posting demos on YouTube.

Utility Belt FX has 3 products cataloged on Equipboard, including Fuzz Effects Pedals, Amp & Cabinet Simulators, and Multi Effects Pedals. Their gear is featured by 2 artists, with the strongest followings in Rock. Notable users include Thomas DeLonge and Mark Hoppus.
