played one last night briefly, defiantly not as long as i'd liked and was very impressed. i nailed the rock tones i had been trying to get out of my fuchs ods, which might be on it's way out the door now. it's the first two rock i've played and it has some mojo. what else is this thing cable of. the tubes are not 6l6's right? i didn't see the emrald pro on the website, is it as pricey as the rest of the two rocks, which could be a problem? talk to me about this amp!
