I know most of us have recognized Rivera amps for some time as quality musical products, but I have reason to renew your enthusiasm for a company that I believe is still underappreciated. I just picked up a used Rivera Fandango 55W 2X12 combo ( powered by EL34s ). Its versatility, tone, and down-home no-apologies-bad-assed-tube-amp-on-steroids-attitude is exceptional. If you prefer 6L6GC power tubes, the Quiana is a close relative of the Fandango thus equiped. A cheaper 1X12, and a more powerful 100W 2X12 is available for both the Quiana and the Fandango models. See the Rivera site for details. If you have tube amp GAS, this is the answer to your dreams.
