You really shouldn't have to do anything special to get rid of the buzz. Usually when u use tape or other resourses you kill the tone of the drum. The drums' tuning, other drums tuning, and the position of the drums, all affect the buzz. You should be able to eliminate the buzz enough to be happy. You will never get rid of it entirely, but enough that it won't be noticed, even when recording. If u do any kind of muffling to the snare, only do a little to the top head, don't go crazy....and make sure that the snares lay flat on the head and are evenly tightened(as mentioned before). Keep working on it, it takes time...God luch.
