So I'm at my friends house jamming, and we go outside to see his hottub cause he said it's draining, and we decide to soak our feet in. At this point, my bass is strapped on. My friend tries to pinch me or something and instincs take over and I naturally flinch, and boing, I feel that bounce of bass of concrete, not good! What would you do? Can this be repaired, if so, how much would it cost. It may be sorta my fault, a little, but I'm still pretty pissed!
