Dirty Haggard Audio is a boutique guitar pedal company based in Portland, Oregon, founded in 2017 by Nick Rogers, an electrical engineer and musician. The brand was built around three core principles: high gain, low noise, and maximum affordability. Every pedal is designed and hand-built in Portland, with many circuits incorporating built-in noise gates and dual-stage RFI/EMI input filtering — technical touches uncommon at their price point.

The lineup spans fuzz, distortion, overdrive, and modulation effects for both guitar and bass. Signature models include the DH-3 DeathFuzz (a Shin-ei FY2-inspired gated fuzz), the Torsion (a three-stage fuzz with integrated noise gate and advanced tone shaping), the Gatekeeper (an octave-down fuzz with synth-like textures), the SQRT (a refined Russian Big Muff-style circuit), and the 797 (a lo-fi overdrive inspired by the DOD 250). Bass-specific offerings like the Degrade and Mangled feature clean blend controls and midrange voicing options. The Strychnine was a collaboration pedal designed with Portland psych-rock band Spoon Benders.

Dirty Haggard Audio has developed a cult following among players drawn to raw, aggressive tones at accessible prices, with most pedals priced well under $200. The brand sells direct through its own shop and through dealers including Guitar Center, Reverb, and specialty boutique pedal retailers.

Dirty Haggard Audio has 14 products cataloged on Equipboard, including Fuzz Effects Pedals, Distortion Effects Pedals, and Overdrive Effects Pedals.
