Hi, just purchased a 56-57 zildjian K 20. It has these brass rivets that say 45 on top of them? Anybody know anything about this? I ask because Ive tried the cymbal without the rivets, with regular steel rivets from a hardware store, and the brass 45 that came in it. The brass 45 sound the best, only a slight difference, prob no difference at all really, but i like em. The cymbal is drilled for 4 rivets, and I only have 3. Im mainly curious, because I dont know much about k's. Were these added later or thats how it came? Thanks in advance.
