In August 1976, Paul Rivera founded Rivera R&D in Southern California to provide musicians and the music industry with state-of-the-art equipment that would meet their requirements. Rivera is a private company. The company has no shareholders and does not have to adapt to trends or sales figures. They direct all his processing power towards creating the best possible guitar amplifiers and effects. There is no room for compromise when it comes to Rivera products. The quality and care of workmanship are at the highest level, which makes the brand belong to the premium segment.

Only Rivera produces all-tube stereo combo amplifiers, the S120 series. Only Rivera builds an all-tube acoustic guitar amplifier, the Sedona. Only Rivera had the foresight and innovation to bring powered subwoofer systems to market more than six years ago.

Each Rivera product is designed for musicians and is aimed to meet their needs. As the company develops, it expands its amplifier production capabilities. With Rivera equipment, you can be sure not only of the absolute best sound quality, but also of well-invested capital, because when older equipment from other brands is withdrawn and abandoned, Rivera amplifiers will still be produced unchanged and will continue to increase in value.
