Scott,
Since I know you are very curious, the two strips on the left side hiding the name of the brand (Kurzweil) are velcro white strips, which I use to fixate my feedback destroyer (Behringer Shark). Once again, this velcro solution, I got it from you guys

. BTW, I recently upgraded my vocal setup. I exchanged my Shure Beta 58a (Dynamic) for a Shure Beta 87a. I couldn't be happier with my upgrade, 87a is a terrific vocal mic!
