Wow! I'm really loving this amp lately after going through some initial frustrations. I also added an EQ in the effects loop which makes quite a difference, but I'm getting some excellent strat tones on the Uk 70's, UK 80's, and Boutique OD models for soloing, and great cleans on the Blackfae 212.

This amp takes a little bit of patience learning its nuances, but once you do, the tones are pretty damn good. At this point, after putting an EQ in the effects loop, I see no reason for a speaker change at all. I think part of it might be that the speakers are now really broken in, and it's just a matter of finding the "sweet spot" on the EQ and gain for this amp.
