Plug & Play Amplification is a French boutique brand founded in 2012 by Sylvain Rousseau, a luthier and audio electronics engineer who also runs Rousseau Guitars. Based in northern France, the company specializes in handmade power attenuators, guitar pickups, effect pedals, and accessories for guitarists and bassists. All products are hand-wired in a small workshop, with components sourced primarily from European suppliers.

The brand is best known for its line of power attenuators, available in configurations ranging from 15W to 100W and a Pro model rated for amps up to 130W. These attenuators are praised for their transparency and value, offering multiple attenuation steps without significant tonal degradation. Beyond attenuators, the lineup includes the NOCAB cabinet simulator/load box, overdrive pedals like the Tube Player and Red is Dead, the Bass Player distortion/overdrive for bass, and a range of guitar pickups spanning Stratocaster single coils (David's Black Strat, Red House 69, Texas Pride), humbuckers (PAF 59 Alnico 2/5, Appetite for Destruction), P90s (Black Dog, Chicago Club), and Telecaster models. The company also offers Marshall Class 5 modification services, speaker cables, and silent plug cables.
