This is us, too. But we’ve recently employed a new worship leader, she’s very keen and professional!
This evening we’re meeting at our ‘morning service’ venue, to try and set up pre-set sound levels/tones for each of us, to make it easier for the sound team each week, because of different rota’d bands. Unfortunately the sound team is where we are short of volunteers, so anything to help is a bonus - hopefully!
Streaming and lack of low down sound was mentioned earlier. If he’s not already doing so, get the sound man to listen to the YouTube mix rather than the stage mix. On ours, this has resulted in the bass and to a lesser extent the drums being wound up significantly on the stream, and they are just about heard...
