They do, and pretty well for that kind of thing, IMO. Without the
speaker/amp modeling, it sounds too sterile and hi-fi plugged direct
into the PA. With the modeling enabled, it's convincing enough. OTOH,
playing through an amp with the speaker/amp modeling turned on sounds
muddy/distant/processed to me. Which makes sense. As I recall, that's
one of the reasons I passed on the ME50, because that stuff couldn't be
defeated.

The speaker/amp modeling parameter is saved with the patch. I have a
couple banks of patches set up with particular effects + an amp sim,
then a couple other banks that are the same but minus the sims. That
way, I can get the same sound whether going into an amp or PA. It
wouldn't be useful to me to turn the amp sim off and on with a
footswitch - it's either on for the night or not.
