Great amp and great platform for pedals. Congrats! There's a reason why you see the HDR on so many stages and why for e.g. Wildwood Guitars did so many demos using this amph. I never really tried the overdriven sound but heard pretty mixed opinions - do you use it and what's your impression? Regarding the loudness, I've heard lots of people complaining about the DeVille - I think the HDR can be regulated pretty well volume-wise.
