I currently still have my ludwig factory snare head on my snare drum. I have had it for a while..and its taken quite a beating...and a bit of the coating is coming off now..i was wondering how much longer i should wait to get a new snare head. I also find it harder to tune now..maybe because the head is worn. Also I need some advice on what snare head to buy..i want a focused head (not too focused)..but i also want a deep punch to it. I was thinking about the Evans Genera Dry head. The snare is 14x8. Any reccomendations?
