I have acoustic drums with quiet heads in my apartment, as well as quiet drumsticks, like those for electric drums. This is enough to not disturb the neighbors. However, when a band comes over and we want to make some noise, it's impossible to turn up the drum volume, even when playing loudly.
These tips make the drumsticks heavier, shifting the balance forward, and hit the toms and solo drums harder, louder and clearer, and also dampen hits on the cymbals.
