Had a ringing overtone in one of my bass drums. I was just going to remove the reso head to eliminate the ring. I read up on the Retro Screen Reso Head, and it sounded perfect for problem. Installed easily, looks great, and fixed my overtone problem. It looked and sounded so sweet, I put one on my second bass drum. Now both bass drums have the deep punch sound of being played with no front drum head, with the illusion of a black reso present!
