That would definitely work. I prefer a dedicated DI so that I don't have to take my amp everywhere. A DI out from an amp will give you a good signal to the board, I just prefer the sound that I get from my Venue DI. It's really just a matter of taste at that point. Although the signal from the amp will always sound less "full" as it will through the PA.
thank's for your answer.
The best will be to have a good acoustic amp and a para or venue Di....
I have to test different acoustic amp whith lyric...anyone does it?
