Lately, I've been getting really bad wrist pains playing upright bass. I had no clue where its coming from until I put 2 & 2 together. I only get these wrist pains when I play with this particular drummer. Not only that, when I play with him, I have to turn up my amp WAY louder than I have to with anyone else. How can I tell him, politely, to bring it down a few notches?? Its a hard situation because he's been a musician for quite a bit longer than me (and is a great musician). But, I just cannot play with how loud he is and risk damaging my wrist and I dont think I should need more than an Aguilar 12 and a GK700RB for a small jazz group. I'm not the only one that has noticed the volume issue either. Any help?? I most certainly dont want to offend him, but no one else has said anything which is really odd. I know its selfish reasons, but I feel I need to step up and say something because I can't keep digging in as much as I do to get some volume and end up screwing up my wrist more.
