I've only had the chance to use the Sennheiser MD 441 in a few different scenarios, but many engineers that I have talked to speak very highly about this microphone in terms of it's versatility. The applications that I have used it for are for both the top and the bottom of a snare drum. Mostly, I used it on the bottom with a Shure SM57 on the top, but also experimented with using the 441 on the top as well. I found that it worked quite well for both applications, but in the end I did like the sound of the SM57 on the top of the snare best and found that the MD 441 was best suited for the bottom. I haven't yet had a chance to try the MD 441 on other drums like tom toms, but would think it would be good for them as well, as is the case with the MD 421s. If you own or have access to a Sennheiser MD 441, I definitely recommend trying it on all sorts of applications to see what will work best for it, which is something I plan on doing as soon as I am able as I believe it will sound great for most applications. The MD 441 is definitley not as readily available as the MD 421, but you can find them around. They will however cost a good amount more. All in all the Sennheiser MD 441 is a very high quality dynamic microphone that should be treated as so.
