I just took a chance on a 70's Zildjian 20" heavy ride cymbal. It's 2689 grams and in perfect condition with a beautiful patina. Heavy rides seem to be out of fashion at the moment, hence the low price. I must say at first listen I'm very surprised at how great it sounds. It has a medium-low tone, not very loud at all with a bit of wash. All in all, it's a keeper. Anyone else have any experience with these cymbals? It is a pleasant surprise for me!
