I don't worry about my onstage sound. I make sure that I can give the person dealing with the sound a DI that sounds the way I want it to.
Anything on-stage is just for monitoring.
However, if the person doing the sound wants just a straight DI with no whistle and bells then that's that I'll give them. Being heard is more important to me than 'my sound' and it's their job to decide how that's best achieved, on that night, in that venue.
