thats a great advantage of digital amps you can back up the settings...I remember a gig out of high school the guy has a Mesa whatever and someone messed up his settings on the front was like 2 rows of eqs and such...it was right before a show and I thought he was gonna cry... with your rigs backed up to a memory stick all you have to do is find a eleven rack and a laptop in the place your playing... backup the new 11rack with your rigs and tada you take your tone wherever you go....kewl.
