Looks and sounds like a really cool amp. Oddly, Doug points out how it's aimed at rock, but then the demo spends almost the whole time focusing on special cases like blues and metal.
It seems like another stab at the Atlantic Series, but with a more Mesa-oriented pitch to differentiate it better. The fact that it ships with EL34 is a big indicator to me. I like the features and I suspect the tone is fantastic. I wonder how it would compare to a RA100.
I really don't like the look of the knobs, but that is changeable.
I have always liked 6V6, as I started with a '65 Deluxe Reverb, and I'm interested in how the different channels in this amp will play with those. I assume that the power rating with 6V6 will be around 20-25W, so that is how you can get a lower power mode, though obviously not so much on-the-fly. Still, it's easy enough to carry a couple power tube duets and change power easily-ish.
Interesting that it's 50W. I wonder if a 100W version is brewing. I also wonder what ELSE may be brewing. Could this be the start of a new line? If so, would it replace the Express series?
