I got it a week ago and have enough time on it to feel comfortable commenting on my first impressions. I played it about five weeks ago at the GC in San Jose and was blown away. I had a few weeks to think about it as it was on police hold. I finally understand the true meaning of "touch sensitivity". This is the first amp that I actually believe has "enough gain" but cleans up without sounding choked. Of course the Emerald is a two channel amp with a world class clean channel as well. Not all was peachy. One of the DPDT switches in the footswitch crapped out almost immediately. A kind forumite has hooked me up with a replacement switch (and a few spares) and I'll whip out the soldering iron on Saturday. Fortunately, I have some other compatible footswitches to get me through tomorrow's rehearsal. But the tone! Luscious cleans and meaty overdrive. Sparkle, girth, 3D reverb, great FX loop. Me likey. A lot. As another Two Rock owner likes to say, "VERY GOOD". Two Rock's customer service has impressed as well. This morning I emailed them with a question about the seven (!) trim pots inside. The response was prompt, polite, and informative. This evening I played with the trimmers that constitute the lead channel EQ. Very sweet. I can't wait to try this out with the band. Having played it in a GC while a bunch of shredders were warming up for Guitarmaggedon, I know it cuts through. With my Rivera to do the clean/crunch thing and the TRock to do the sparkle/sweet thing, I'm not sure where my recently acquired Fuchs mod stands. Its EL34 power section certainly provides a distinctive sonic signature but I'm not sure it has a niche in my lineup. We'll see how I feel in the coming months. It's a great amp but doesn't do it for me the way my Emerald does. VERY GOOD indeed.
