I've been using the AKG C 418s for about five or six years, as they were the first microphones I bought to record tom tom drums with. I like them because of how easy they are to place on drums and because I usually get great sounding results with them. While I only use them for drums, they are suitable for any situation where you would need to clip a dynamic microphone on to the instrument. If you buy these mics within the AKG drum pack that comes with the D112, you can get a killer deal in terms of per mic price. In fact, this would be the only way I would recommend buying these mics, because if you buy them on their own they are way to expensive for what you are getting. The mics definitley have a good sound quality and its small size is convenient, but there are better sounding microphones out there for a similar price or cheap, including the Shure SM57 and the Sennhesier 421, which are both better choices in my opinion for recording drums. The C418s are also a great deal if you can get one used as they good for quite cheap on ebay. I wouldn't recommend these for the professional studio environment, as there are an array of mics that sound better, but for the project studio owner that is looking for a good price (used or within the AKG drum pack) and a quick set up, these are definitely worth a try.
