Ground Control Audio is a boutique guitar effects pedal builder based in Montreal, Canada, founded in 2016 by Sebastien. The small-batch operation grew out of the founder's interest in post-rock and ambient music, with pedals designed in-house rather than as clones or reworks of existing circuits.

The brand's catalog leans toward textural and ambient-adjacent sounds alongside heavier fare. Notable offerings include the Noodles, a three-band active EQ and boost pedal; the Locust, a high-gain distortion/fuzz aimed at shoegaze, noise, doom, sludge, and stoner styles; and the Serpens, an LED/LDR optical compressor often paired with the Amaterasu and Tsukuyomi tone-shaping pedals. The lineup also includes oddball entries like the UwU Virtual Pet Buffer, a buffer pedal with Tamagotchi-style interactivity.

Ground Control Audio developed a following in the math rock, midwest emo, post-rock, and heavy/ambient communities, distributed through boutique pedal retailers in North America and Europe.

Ground Control Audio has 10 products cataloged on Equipboard, including Overdrive Effects Pedals, Compressor Effects Pedals, and Boost Effects Pedals. Their gear is featured by 2 artists, with the strongest followings in Rock. Notable users include Yvette Young and Eirik Stordrange.
