Haggtronix is a small-batch effects pedal and noisemaker builder based in Nashville, Tennessee, owned and operated by Paul Haggard. Each pedal is hand-wired, hand-assembled, and hand-screen-printed one at a time, with an emphasis on loud, thick fuzzes and distortions alongside vintage-style recreations of out-of-production circuits and custom noise-generating instruments.

The lineup leans heavily into high-gain territory with fuzz and distortion boxes such as the Rotten Sorcerer, Dark Sorcerer, Grassman Fuzz, Harvester Fuzz/Boost, and Executioner, along with overdrives like the Klagg Klone, Satori, 606-Screamer, and the Mothman Dual Drive. Haggtronix also builds the DarkVision spring reverb and fuzz, the Illuminator boost, the Cerebral Specter, and the Triangle Wave Generator, plus collaborations like the Fortune Teller Dual Modulation built with Monkey Riot Pedals.

Because units are built individually in small numbers, many models sell through quickly and appear on the secondhand market through Reverb, Guitar Center, and independent boutique shops. The brand's aesthetic — occult and horror-tinged artwork, hand-painted enclosures, limited color runs including glow-in-the-dark finishes — has helped build a cult following among players chasing heavy, characterful dirt tones.

Haggtronix has 1 product cataloged on Equipboard, including Fuzz Effects Pedals.
