CAST Engineering is a boutique guitar effects pedal builder based in Atlanta, Georgia, founded by Steve Evans in 2015. The company hand-builds its pedals in-house using original circuit designs, and markets them with a lifetime warranty. Its tagline, "Casting yesterday's tones into tomorrow's technology," reflects a design approach focused on classic sounds paired with straightforward, minimal-control layouts.

The product line centers on drive, fuzz, modulation, and delay effects. Notable pedals include the Texas Flood overdrive, inspired by the Cesar Diaz-style drive circuits associated with Stevie Ray Vaughan's rig; the Gypsy Haze, a fuzz with octave-up and stutter modes; the Pulse Drive, an analog tremolo with 30 dB of boost built around an Anthony Leo-style tremolo circuit; and the Casper, a three-knob digital delay. The Peace Drive, developed in collaboration with blues guitarist Mike Zito, is a dual-gain pedal that pairs a boost and an overdrive with switchable circuit order.

CAST Engineering pedals are sold direct and through an international dealer network that includes Chicago Music Exchange, Distinctive Guitar, and Guitar Center, among others. The brand has drawn coverage in outlets such as Premier Guitar and Vintage Guitar, and has been profiled in Japan's Effector Book.

Cast Engineering has 4 products cataloged on Equipboard, including Overdrive Effects Pedals, Delay Effects Pedals, and Tremolo Effects Pedals. Their gear is featured by 1 artist, with the strongest followings in Blues. Notable users include Christone Kingfish Ingram.
