The KickPro Pillow design was the result of thousands of recording hours and messing around with anything and everything inside a bass drum. I was searching for something versatile with a bit of weight but it also needed to be easily manipulated and STAY where you put it. The KickPro works great for sensitive and heavy players alike and is easily adjusted for light or heavy contact against the heads. It will not move and your bass drum will sound and feel like you want it to. Experiment front to back, inside and out. Thanks for all the support out there!
