I've heard this mentioned in the past and really never thought it was necessary , until now that I'm taking my AX8 on a fight.
I'm only bringing it for my own amusement , not business. Personally , I think the ideal travel FAS product would be an APP that I could have loaded in my iPad pro , that would have a handful of my favorite presets for the road , for fun. I'd pay ..... $500 for the AX8 brain in my iPad , easily. Play and configure presets anywhere.
As far as changing the AX8 , and creating a smaller floor unit....Nah. Amplifier is smaller and sounds decent. It's too limited in design and lack of switches for my liking. AX8 is perfect.
