Sounds great to me now, sounded great before. One thing I notice over the last couple of firmware and betas is that I'm making far less advanced parameter tweaks than I did before: and those mostly relate to balancing guitar/pickup with cabinet resonance characteristics. It may be due as much to my increasing familiarity with the unit as to performance enhancements.
Given that some of the under the hood algorithms have changed, I don't expect any previous preset to sound exactly the same: Even if they're very close, I prefer to rebuild from the default: It usually just takes a couple of minutes, and often enough I come up with a little tweak I prefer to what I'd had before. If nothing else, its reps on how the controls influence the sound on that particular amp model.
I am really enjoying the effortless transition between sweet melodic licks and the breakup of chording with the new 5F1 Tweed EC (cab 080 or 183). Don't know why, but it makes me want to fire up the grill and barbecue something: Maybe because it's fat, greasy, smokey, and goes down so easy. Yum.
