DopeFX is a boutique guitar effects pedal builder based in Macclesfield, United Kingdom, operating under the tagline "Hand Crafted Under The Influence." Pedals are wired by hand and built around premium components including true-bypass Neutrik jacks, ALPHA pots, high-quality capacitors, and 1% metal-film resistors. The brand has developed a reputation among UK pedal enthusiasts for affordable, well-built circuit clones and original variants, sold primarily through Reverb, eBay, and the company's own online store.

The lineup leans heavily on classic fuzz and drive territory. The Boba Fuzz and Iron Lung are takes on the Zvex Woolly Mammoth circuit, with the Boba Fuzz adding a mids control to push the voicing from bass-heavy to a fuller, punchier fuzz. The Earth Dweller is a Big Muff–style fuzz, while the Dazed and Confused is modeled after the RAH-style Hiwatt tone associated with Jimmy Page's 1970 Royal Albert Hall performance. Overdrives include the Everything Zen, a Zendrive-inspired circuit, alongside other Klon-style and dual-circuit designs.

DopeFx has 3 products cataloged on Equipboard, including Overdrive Effects Pedals and Fuzz Effects Pedals.
