Just like toms, I have most all the mics I want for kick drums. First, I really like my kick mic dead in the port of the drum, angled right at the beater. I put it so that the silver grill is just inside the port, and the black back half is sticking out the back. Next, experiment wiht a little EQ if you want. I am fond of a 2 db boost at 90, a 4 db cut at around 350, a 3 db boost at 4k, and another 3 db boost at 8k. That is more of a really driving rock kick drum, if you want a little more mellow bump, skip the 2 HF EQ's, an maybe even drop some more of the low mids.
I have kind of gotten to the point now where I don't really care to much which kick mics I use. I have
an Audix D6, EV PL20, Sennheiser 421's and 602's, Shure Beta 52's, beta 91's, and even some PG's somewhere, and AKG D112's. IN the end, I think my favorite sounding one is the Sennheiser 602, although I have not used it in the studio yet. The problem I have found is that it is very prone to a really low end consatant feedback when it is placed directly in the port of a kick. I even tried another 602 to make sure it was the model and not just the specific mic. If you take the mic out of the kick, the problem goes away. Basically it limited me to running a 602 on kick only when I also had a monitor console running with gates. Next, I hate both the 421 and the EV PL20 on kick drums. They both sound boxy, with no low extension, and dull to me. However, many people like them. The Beta 52 sounded just fine to me as well as the Audix D6. In the end, I think I end up recording with the AKG D112 the most because that was my first kick mic, and I have learned it really well.
If you ever get a chance, try running a condensor at the same time. Try laying a small diaphragm condensor (USE THE HIGHEST DB PAD IT HAS) on a small piece of foam inside the kick. Try angling it about 45% away from the beater, at about mid way into the shell. Check the phase carefully with the dynamic, and lay some tracks. Having the inside condensor will really increase the type of sounds you can create without having to dump as much processing on the D112. Also experiment with trying some condensors Lg and Sm on the outside as well. Have fun, and I am sure that soon you will figure out how your D112 works best with your recording style and you will be able to get some better sounds. The D112 may not be the best mic in its class, but its certainly reliable, and well worth what it costs
