Rivets are used to add character to the sustain of a cymbal. Traditionally used to manipulate a cymbals response by adding as many or few as needed for the desired sound.
Installation is a breeze, simply insert the rivet into the hole, and bend the bottom ends out.
So if you have a cymbal that had rivets at one point or if you just want to change the sound of your cymbal, grab a pack of Meinl Cymbal Rivets and enjoy the ride.
Disclaimer: These are designed to work in existing holes, drilling new holes in your cymbal will void the warranty.
