We have a drummer who always plays as loud as he possibly can and it's really starting to piss me off. We ask him every time not to play so loud but he does it anyway. It's like he has no control over his dynamics, he just hits the drums as hard as possible. I play an 300 watt all-tube Ampeg SVT through an 8x10 and I turn it up until it distorts and I actually have a hard time hearing myself. He wanted to play today but I stopped playing and walked out of the room after 2 or 3 minutes cause he started playing ridiculously hard and it was hurting my ears. I don't know what to do, I always tell him to not play so loud but he does anyway.
