I bought some Beyerdynamic mkv 87 clips to be more flexible using clip mics by choosing what mic I use... as clip mics aren't always so great. With this gooseneck I can apply my sm57 etc at a proper angle away from the drum's skin. Once I noticed goosenecks exist and wanted to try it out, I got immediate satisfaction and from now on always carry some of them in different sizes for problem solving. Firstly I was in doubt wether to invest more money due to quality and go for the K&M goosenecks but to try the concept out I went for Gravity, and am indeed satisfied. I bought the size S, M and L and am a happy musician and technician.
