Every microphone has its purpose. Some are for vocalists to hold in hand, some are for recording booths, some are for the edges of the stage and some are even for focusing on just one spot. But without a doubt, some of the most versatile mics are instrument microphones. There are tons of different instruments, and the ability to record a huge variety of them with professional quality is no easy thing. Still, you'll find plenty of mics here that can do just that, along with a good selection of specialized and instrument-specific types as well.
There is, of course, one type of instrument that's especially demanding on its microphones, and that's percussion. When it comes to purpose-built instrument microphones, drum mics definitely make up the lion's share. There are a few reasons for that, one of which is that getting the best results on a drum recording involves putting a dedicated mic on each drum. That's why you'll see plenty of packs here with a whole set of drum microphones, so you can get the whole kit fitted out at once. Also common are standalone kick drum mics, which are specially tuned to handle the low frequencies and the heavy 'punch' of air that a bass drum creates. Where generic mics would be overwhelmed, a kick drum mic stays clear and distortion-free.
A few of the other specialties you'll find in this section are dedicated vocal mics, clip-on microphones for brass instruments and dual or paired models ready for stereo recording. Be sure to pay attention to the response pattern, as well; that'll be important in making sure the mic only picks up the instrument you want it to.
Ultimately, it's all about what you plan to record and what you need in a mic. For live or studio use, no matter your budget or instrument, the right microphones to fit your needs are waiting right here. The best advice anyone could give you is to take your time and consider the options carefully; you'll discover the best fit for your instruments soon enough.
