Yes, we had issues with loudness as well. I do not understand but some of our guys have to Play ultra-loud to get the right Rock n Roll feel I guess. It came to a point where our techie mentioned that this is not healthy, b/c during a gig measured at the FOH we had reached 120db. He told us that this is not allowed in Germany over a longer periods of time. Or at least you have to set up warning signs to inform the audience about that these loudness Levels can damage your hearing.
With some tupe amps the problem is, that the are very loud even if the volume knob is set fairly low, that makes it even worse for the techie, b/c the amp blows everything away and he is not in a situation to create a decent mix. But I am not sure, if the other guys will understand the advantages of a silent stage. They probably miss that Rock n Roll Feeling, where it has to be loud. I can only play with filtering ear-plugs due to some advice of my doctor.
