both me and my brothers friend have this problem with i am playin my bassdrum pedal tends to slide not the drum just the pedal. Its not moving away from me its just twisting, like the spot where your heel goes slides inward and then i am not hitting the bassdrum head on. I have tightined it quite a bit and it continues. I do not want to tighten it even harder because it has started to ruin the finish. I have my kit on carpet so the floor isn't the problem. My kit didnt come with a rubber strip on the batter head hoop so im wondering if that might be it. I forgot to pick one up from the drum store the last time i was there. But anyways if you know a way to stop please let me know.
