I'm working on an ad project with both the HXDA and the DG30 this weekend. And I'm using the amps at the volumes they were intended to be used, which is to say, gig-loud.
That's pretty loud, but not so loud that the neighbors are complaining.
What strikes me about both amps is that I never think, "Gosh, if only I could get these amps to do this other thing..."
This particular project involves very heavy rock. Much heavier than is my usual thing. While the amps are very gainy in and of themselves, I'm also shaping the tone with pedals because that's what I do. And I'm getting exactly what I want (and more importantly, what the client wants).
I know I'm repeating myself all the time, but I am really, really happy with these amps!
