Personal opinion: I'm seeing it more and more all over the place: wonderful programmable amps which because of any, often minor problem, have to be junked, because, of course, info is unavailable and even if you get it, it's too complex to be used.
I'm getting into the mindset that the sensible option is to get a multi emulator *pedal* or POD and plug it into a regular amp.
Failure of one does not kill the other, separate parts tend to be more robust and worst case, one dead means you can still play with the other and save the night.
POD dead?: plug straight into the amp and play somewhat simpler, less effects.
I bet the *music* won't suffer that much.
Amp dead?: plug the POD straight into the PA.
While in the full digital combo amp, any problem means very frustrating not playing at all.
