At a recent gig with a really nice sound setup, I asked the sound guy to make the monitor mix the same as the front but we don't need the drums or bass in the monitors. He reiterated that he would go around one by one to make sure we are happy. I tried to reword what I wanted, but he still didn't get it. The sound was very good still, but we want to hear what the crowd hears. It has worked very well for us when we do our own sound. How else can I explain this? We'll be playing there again on out the dock this time.
