S-Cat (Space-Cat Audio Technologies) is a UK-based builder of hand-made electronic instruments and effects, founded in 2008 by Arron Courts and Abegael Saward. The company began by selling circuit-bent toys and machines on eBay, accompanied by a YouTube channel demonstrating the modifications, before transitioning in 2013 into designing and manufacturing its own original hardware. All products are assembled to order out of the duo's Phonic Potion Studio.

The S-Cat catalogue centres on analogue and hybrid sound generators and effects aimed at electronic and dub producers. Notable products include the Dub-Siren, an analogue oscillator with LFO inspired by Jamaican sound-system sirens; the Bass-Synth, a CV/Gate-controlled monosynth built around the CEM3340 VCO; the Dubsta-Delay, an analogue BBD delay using four MN3005 chips; the Time-Freek digital delay; the Filter-Phase; and the Double-Trouble distortion. The brand has supplied custom and stock units to artists including Jean-Michel Jarre and Liam Howlett of The Prodigy.

S-Cat has 2 products cataloged on Equipboard, including Effects Processors and Synthesizers.
