General
Your cymbals are an integral part of your sound, and they may very well be one of the most personal parts of your percussive palette. As such, many people create custom stacks or modify their cymbals to get a unique sound. If that is something you'd like to do as well, take a look at these Sabian Sizzle Rivets.
To fit these rivets, you will have to drill some holes in your cymbal (or get a professional to do so, if you feel uncomfortable doing it yourself), but once they're in place, they will dramatically alter your cymbal sound. Because of the interaction between the vibration of the rivets and the cymbal itself, the cymbal's sustain will be enhanced and the rivets will give the cymbal a beautiful sizzle effect.
