Fuzzlord Effects is a guitar pedal company based in Eugene, Oregon, founded in 2016 by musician and electrical engineer Jason Johnson. Operating under the tagline "Tuned For Doom," the company handcrafts effects pedals aimed at doom, stoner, sludge, and other heavy music styles, with a focus on fuzz, distortion, and ambient textures that draw on classic out-of-production circuits reworked with modern features.

The lineup began with the FET120, a preamp-style overdrive, and has grown to include pedals such as the Void Master and the FU-2. Beyond the product line, Johnson runs an active YouTube channel demoing pedals and doom rigs, and hosts The Fuzz Life Podcast, which covers gear, doom metal, and interviews with other builders and players.

Fuzzlord Effects has 13 products cataloged on Equipboard, including Fuzz Effects Pedals, Overdrive Effects Pedals, and Distortion Effects Pedals. Their gear is featured by 1 artist, with the strongest followings in Rock and Metal. Notable users include Mike Scheidt.
