Before I dive in, can you give an example of what you had to do generally to your presets to make them work after the update? By this I mean, was it just level, or did the update screw with the basic tone/sound to the point that a lot of tweaking was required? I don't have as many working presets as you do, maybe 40 or so, but I worry a little about the workload if the update sends all my gigging presets out of whack. Plus, I tend to do all my editing via Axe-Edit, and in this beta, that's probably a no-no at this point.
