Kuassa's Amplifikation Rectifor pays homage to the Mesa Boogie��historically renowned as the first boutique guitar amplifier that changed the face of music with their rectifier design. This amp is not only known for a single sound character but it delivers a wide range of tones, from rounded jazzy cleans, warm crunch, biting overdrive and thick high gain distortion. Players of heavy music such as Tool, Soundgarden, Incubus, HIM, Linkin Park, Avenged Sevenfold, System of A Down and countless others adopted the boogie tone from this series of rectifiers.
