The snap in drum key holder is a one-of-a-kind snare drum feature. Often talked about with the Gretsch die hards, the snap in key holder does exactly that, it snaps your Gretsch drum key into your snare drum and holds it in a secure position until you need it. Just pull the key out of the holder and you're ready to tune or tweek your kit. The snap-in is available as an aftermarket part or it can be ordered as a build option on almost any USA factory snare drum.
