YOUR RIVERA AMP IS AN IMPORTANT PART
OF YOUR SOUND
Your sound is your signature, your mark, your voice. An amp only deserves to have your guitar plugged into it
if it can deliver the tone you want—and, of course, the dependability you need. It’s as simple as that. And it’s
exactly why you bought your RIVERA amp. For that, we thank you, and we’re confident that you’ll enjoy
your amp for years to come.
Many factors go into creating a great amp—experience, an understanding of what guitarists want, and a lot of
hard work. You’ll notice that tone isn’t on any parts list. Roadworthiness isn’t, either. And there’s no law saying
that an amp must sound good or be well-made. But we dedicate ourselves to making the best-sounding, most
reliable amplifiers anywhere. That’s why we use only the highest-quality components, regardless of price. Such
features as metal jacks, ultra-strong dadoed cabinet construction, and highest-quality electronic components
are part of our uncompromising approach. They’re chosen for their precision, strength, and ability to with-
stand the rigors of years of use—and occasional abuse—on the stage and in the studio. No compromises are
made because cutting any corners—no matter how small—means settling for second best.
This requires dedication to you, the guitarist, and a belief that an amp is more than a collection of parts. It’s
part of your sound.
