with the Epsi, there are only cabs that you want, with no fizz. you could load a fizzy cab if you wanted to, but none in there by default.

the default cabs are more mids heavy with zero fizz. the cab i loaded (that you can hear in the clip) actually has a little fizz or high end, but it's not obnoxious.

you are correct, there are certain eleven rack cab/mic combos that will fry your ears. i tried to dial all of that fizz on on the superpack presets.
