I’m a very experienced drummer, 40 years playing since I was a child. I have only once cracked a cymbal in that time. However, I’ve been playing with a louder band recently and although I’m only a medium volume player I’ve notice some tiny cracks around the bells on my zildjian a custom and k custom crashes. I’m sad to see these as I love these Cymbals. How can I stop this from spreading? What’s the best way to protect the centres of my cymbals from this. The kit I play is the same however I am using a rehearsal kit with this band but I put new sleeves and washers on the cymbal stands. Advice appreciated.
