Overall Rating
Playability and Feel
One of the best kept secrets
Would you consider this product to be made well? How dependable?
Top notch, what you would expect for an amp this expensive. Love the quality components and finish.
How has it stood up over time?
Built like a tank and has taken everything I've thrown at it for 2 years now.
Your general opinion of this product.
This amp is hands down one of the best in the world. I play Mesa primarily and I love this amp. I actually have the 2X12 version. As anyone that can do some research will find, Mr Rivera comes from the Fender school of amp building. Like Mesa, Rivera uses similiar circuits to Fender in its construction. Your getting that more bottom heavy warmer tone, not as middy as a Marshall.6L6 tone which is what I prefer.
Playability and Feel
How does it feel, Heavy, Fast, Chunky? How was the neck? Are the controls easy to get to while playing?
As far as feel....its one of the heaviest amps I've ever encounterd. So much so that I installed some high quality Mesa casters to roll it around.
Bright and snappy? Dark and smooth? Were the pickups hot, mellow, thick, thin?
6L6 tone is darker anyway, and this amp favors the rythm guitar player, the riffer, the chorder who loves warm smooth slightly bassy tone. A lead guitar player might choose a Marshall or EL34 equipped amp.
How did the stain or paint job look?
It is covered in a carbon fiber like leathery tolex ? Very sharp in appearance and feel.
How was the action out of the box?
