What is a Cymbal Key Hole ?

A Keyhole happens in a cymbal when the cymbal
stand does not have a protector on the metal. The cymbal rubs against
the cymbal post and over time starts to cut a channel into the cymbal.
It looks very similar to a house key. Once this happens to a cymbal,
there is nothing you can really do to fix it. the best thing is
to prevent it from happening by using plastic or rubber sleeves
on the cymbal stand post.Here is a Cymbal Stand PostThis is what a key hole looks likeThe Drum ExpertsJim and Dave
