VS Audio is a Greek effects pedal company based in Ilion, near Athens, that designs and hand-builds analog guitar effects. The company was started in 2011 by electronic engineers and musicians Panos Sotiropoulos and Costas Theoharis, who initially operated under the name "Versus Pedals" before settling on VS Audio. Their first release was the Project Diana delay, followed through the mid-2010s by the Fuzzytale fuzz, Vibler chorus/vibrato, Operation Trinity distortion, and the Royal Flush dual overdrive.

The lineup has since grown to cover overdrive and distortion (Royal Flush, Royal Flush Plus, Golden Royal Flush, Platinum, BlackBird Deluxe, Pandora), modulation (JangleMaster, Alchemy MKII, Vibler), and delay/reverb (Aftermath, Straight Flush, Project Diana). The pedals use all-analog signal paths and are often pitched around classic amplifier-style voicings.

VS Audio is distributed through boutique retailers in Europe, North America, and Australia, and is generally positioned in the affordable boutique segment — hand-built in Greece but priced below much of the North American boutique market.

VS Audio has 8 products cataloged on Equipboard, including Overdrive Effects Pedals and Fuzz Effects Pedals. Their gear is featured by 2 artists, with the strongest followings in Rock and Blues. Notable users include Chris Buck and Michael Nielsen.
