Thank you so much.
To answer your question, yes, they use stage rigs there, and in my case, I was borrowing Cory's (TB:Saluki) Bergantino AE410, driving it with my Markbass F1. But there's also a full PA with subs, so a DI line was also being used. I do play in another church, however, which is smaller, but the same kind of very progressive/contemporary theme, and they do use strictly IEM's/DI on stage (though still a full PA with subs for the FOH). That church uses an Aviom system for stage monitoring, and I have some dual and also now some triple driver IEM's I use there. Oh, and the Sadowsky sounds phenomenal through those, too.
