Drum Keys. There are about a million of these things, coming in all shapes, sizes, and types. Many drum keys are for different situations, or applications, such as high-tension tunings, or speedy quick changes with your heads. When it comes to these situations, it's convenient to have a good tool for the job.
Pro-Mark is a company known for they're professional quality drumsticks. Now they have applied that same reputation to their other products such like their line of drum keys. The Dk30 drum key by Pro-Mark is a ratchet drum key that is great for high-tension tuning, and ideal for fast quick-changing of drumheads. I personally purchased one myself and was impressed with it. However I think the key will better suite marching band applications better because of the key's high torque capacity. Great Product, very sturdy, nice chrome finish with Pro-Mark Logo, and works just like a traditional ratchet in your tool box. I suggest you try one of these out, or you can even try to make one of your own!
