|"Grover Pro has been the leader in custom drum building for many years, so when I had some ideas for a custom 4-inch drum, they were clearly my first choice. Grover Pro incorporated their new ITaP technology and I was blown away with the versatility of the drum. I couldn't be happier with the result!" —Will James, Principal Percussionist, St. Louis Symphony|
Our revolutionary "Independent Tension and Pressure" (ITaP) technology is built around an independent snare depth control. Our ITaP system allows you to easily adjust the distance of the snare cables from the snare head. This means that the snare pressure (or sound quality) can be adjusted independent of the snare tension (or sensitivity). The ITaP system provides you—for the first time—complete control of your sound to optimize every performance.
Years of snare research and development brings us to the conclusion that runs contrary to the traditional concept of snare functionality. By questioning everything believed to be true about snare response, we unearthed the shocking truth:
Just because you play at the edge of the top (batter) head, does NOT mean that the bottom (snare) head will vibrate at the edge. The fact is that the sound produced by snares comes from the center sector of the bottom head.
Think of it this way, you would not jump at the edge of a trampoline. That’s because most of the movement and energy comes from the center section of the trampoline’s surface.
So, while playing softly at the edge of the top head makes sense because the TOP head vibrates less, it does not mean that the bottom head is vibrating at the edge directly below!
Here is a more scientific explanation provided by acoustics expert and inventor Calvin Rose:
“So, let’s talk about why Grover Pro’s snares perform better and give you more control.
#1. They lay FLAT across the head, providing significantly more surface contact, resulting in greater snare clarity.
#2. The largest displacement of the drum head’s fundamental vibration is at the CENTER of the drum head as shown in the image below.”
Don’t be too upset. Approach this concept with an open mind,…but, don’t take our word for it…try Grover Pro snares and listen for yourself!
