Demonic Machines is a hand-built guitar and bass effects pedal brand founded in 2019 by Lucky Murdock (Lucky the monster) in San Diego, California, and later based in Minneapolis, Minnesota. The company is LGBTQ+ owned and operated, with a visual identity built around hand-painted enclosures, irreverent artwork, and the tagline "#NOTyourBro." Its circuits generally take classic stompbox topologies as a starting point and push them toward wilder, more aggressive territory.

The lineup centers on high-gain dirt pedals. The Fukt Fuzz (previously sold as the Glitch Fuzz and Truffle Fuzz) is a square-wave fuzz with a blendable sub-octave voice capable of sputtering, synth-like tones. The flagship Demonic Machine is a dual-voiced Big Muff-style fuzz with a three-band EQ, drawing on a Fran Blanche NYC Reissue Big Muff π circuit for its high-gain side and 1N3666 germanium diodes for its lower-gain setting. The Alleborith is a RAT-style distortion with a clipping toggle for germanium, silicon, LED, or no-clipping modes, and the Πτηνος (Ptenos) uses cascading MOSFETs for a high-gain, tube-like distortion voice. The God's Eye rounds out the line as an overdrive/boost/distortion.

Pedals are sold direct and through boutique retailers including Truetone Music and Reverb, and the brand has built a following in the DIY and boutique pedal community through coverage on outlets like Spin and Guitars For Idiots.

Demonic Machines has 11 products cataloged on Equipboard, including Fuzz Effects Pedals, Overdrive Effects Pedals, and Filter Effects Pedals. Their gear is featured by 2 artists, with the strongest followings in Metal and Rock. Notable users include Sammy Duet and Jamie MacDonald.
