Speaking about guitar amplifiers, there is one name that is highly regarded as
the staple of high gain tone: Mesa/Boogie*. Historically renowned as the first
boutique guitar amplifiers, Mesa/Boogie* 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. What was interesting about the rectifier
series was how 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. It’s probably safe to say that Mesa/Boogie had a big
contribution to the evolution of the music scene since the release of Dual and
Triple Rectifier in the early 90’s.
Kuassa developed and carefully modeled the rectifier design to present its
sound and performance to your desktop as the Amplifikation Rectifor. We also
improve the entire user interface to bring maximum experience for our users.
Thank you for choosing a product from Kuassa!
We encourage you to take A time to read this User Manual thoroughly
to ensure trouble free and proper operation of the software.
