If you want a nice clean transition between the two tones, set up a dual amp patch. Clean amp in PATH A, and dirty amp in PATH B. Assign each one to the expression pedal, and you can morph seamlessly between the two sounds without changing patches or engaging any footswitches at all.

this is a good solution, but I am trying to do this change with a footswitch, I mean, the smoothness is not my priority. But i think your solution is the only one existent hahahaha thank you!!

Have you tried assigning the 2 amps to the same footswitch in controller view and have 1 amp off and the other one on? Then, when you press that footswitch, it would toggle the 2 amps to their opposite status.

I tried this, but the sound is not good. There is a clean awful sound when you turn any amp on. But thanks for the help!

 In few words: I want to start a song with a clean sound of a fender tweed and then change it to a distorted sound of a Mesa Boogie. Let's say that I want to play Fade to Black from metallica, how can I change between these two amps using just one footswitch? I have pod hd500X for over a year and I just can't do that, its so frustrating. Thank you!
