Quick Take- Revolution's 2nd Generation Firefly Dynamic Tuning Device

Have you ever held something in your hand and wondered, “How’d they do that?” That was my reaction to the 2nd Generation Firefly Dynamic Tuning Device (FF2). Note that it's not called a drum key—because it’s a dynamic tuning device that lets you achieve ultra-precise tuning.

APPLICATION

The FF2 performs like a regular drum key to turn your drum's tension rods to replace or tune your drum head. However, this key's seamless "ratcheting" bearing lets it function much like the old-fashioned ratchet-style drum key, but without the “teeth” in the ratchet gear—which is a good thing: the gears in ratchet keys make noise and limit precise tuning, and the size of the ratchet teeth limits precise tuning.

The FF2 has a drum key head on each end. One end is the “tighten” end and the other side is for loosening, so, there is a “correct” side to place the key. The handle (crank) mounts in the center and is anodized in a distinctive aluminum red. The crank also has a hole on one end, so you can place it on a key ring or lanyard for easy access.

One feature that really stands out about the key is the seamless and smooth operation. You can perform extremely precise tuning with this device, with much greater speed than a stationary key.  Additionally, a knurled area on both ends of the center stalk that allows you to speed-turn the center post when you move beyond the need for the handle. (See video below for a demonstration.)

HIGHLIGHTS

Benefits:

• Made with CNC Precision
• Unlimited tuning positioning possible
• Ultra-smooth bearing action
• Useful for all drum applications (concert, drum set, etc.)
• Visually appealing
• Quiet Operation
• Extremely affordable

Limitations:

• None that I've found.

Request:

• It would be great if there were markings to help the user know which end tightens and which end loosens. This could be as simple as markings on the edge of the center crank handle.
• Make a long handle version for drum corps and marching drum tuning.

While a drum key might be a small thing to some drummers (I can say this because I’ve a drawer full of them), a dynamic tuning device is an entirely different proposition. I encourage all drummers to have a 2nd Generation Firefly in their tool or stick bag. You, too, will be asking, “How’d they do that?”
