I have to say, these are great…and they work. I’ve replaced all of the felt washers on my personal drum set with these. Here’s my personal application and how Cympads have helped: My favorite genre of drum playing is Jazz. I keep time with a Sabian HHX evolution 20″ ride cymbal and have always felt the cymbal has a little too much “punch” and emits louder, long washing overtones when you get into a fast swing pattern. Don’t get me wrong, I love this cymbal, but have always wanted to tone it down a bit while playing fast patterns and cut out some of the wash…Basically make it a little “drier” in sound. Cympads have fit the bill. I put some of these bad boys on, played around with the different sizes to get just the right sound and…viola, instant dry….There’s a wide variety of sizes of Cympads to get just the right sound out of your cymbals. It’s like finally having adjustability for your cymbals…How they work: The “Cympad Moderators” normally go on the under side of the bell and basically act as an “adjusting” pad–they come in various sizes. The “Cympad Optimizer” is a standard 40mm pad that normally goes on the top of the cymbal bell (Basically used like a standard pad. Can be used on top and bottom). However, I’ve been trying both in various places to get just the right sound I want. The various combinations make it easy to set up, test and play around with. They even have a hi-hat kit as well. Definitely worth giving some a try.
