Dirt Monger Instruments is a small-batch guitar effects pedal builder based in Lindsay, Ontario, Canada. The company makes both original designs and tribute-style takes on classic dirt circuits, with much of the catalog focused on high-gain distortion, fuzz, and HM-2-style voicings. Pedals are built to order in Canada, and the brand markets itself with the tagline "dirtboxes designed and built in Canada."

The lineup leans heavily on dirt and noise. The Leviathan distortion offers 18-volt headroom, a series/parallel blend, twelve frequency cutoff settings, mid and bright EQ gyrators, and 64 clipping combinations. Other releases include the Bigger Muff (a dual-circuit pedal pairing a Big Muff Pi voicing with a Muff Fuzz Boost and a stacking-order toggle), the American Metal and Grunge pedals (DOD-inspired circuits with reworked EQs and added clipping options), the Bass Grunge, the XT-2 Xtortion Tribute, the APMD-2 HM-2 tribute, and a Six Band Graphic EQ.

Beyond dirt, Dirt Monger also produces the As Above So Below, a PLL octave synth pedal. Distribution is direct through the brand's website and Reverb shop, and the company has built a following on Instagram, YouTube, and Facebook through pedal demos and limited-run drops aimed at the boutique high-gain and HM-2 community.

Dirt Monger Instruments has 2 products cataloged on Equipboard, including Distortion Effects Pedals and Fuzz Effects Pedals.
