Well I happen to like my drums to have as little overtone as possible. For some guys , they may be a little too thuddy, if you know what I mean. So they may not be the best suited for recording. However I feel in a live situation, especially ones where you are having the drums miked, they work great. Sure beats having to put pieces of duct tape on the skins.
Plus, they last forever. I use a heavy stick, a 2B, and I tend to hit hard sometimes and I've yet to put a hole thru one yet.
Evans still makes them. I have them in black, on all my drums, including the bass drum. Not the snare, of course.
Peace, TED
