I'm considering purchasing one of these amps. I've read great things about both of them...but have not played either. I'm curious if there are any TBers that either own both or have A/B'd both. Price, wattage, and size are the obvious differences, but I would like to know more about the differences in tonality; low end - tight/loose, mid range - smooth or aggressive, clarity/presence, overall volume and headroom, - and any other factors that are relevant to tone and performance. Thanks!
