What's the difference between a Mesa Short head, and a standard head (aside from size it seems)? Does it affect the tone of the amp at all?

Are you talking about the Marks?

It just has a few of the features on the front moved to the back. No difference in tone or number of features.

yeah, on the mark's it's the difference in placement of an EQ setting (either always on, footswitchable, or always on the rhy2 channel) and a voicing switch for the lead channel.
