There are several angles to this EZ tip(s):
If you only need or can only afford one microphone-make it a large diaphragm condenser mic of some sort. Prices are all over the map-with good quality all the way around-from $100. To $3000.--or more. Most home recording today is done one mic at a time….a vocal track, an acoustic guitar, an electric guitar, etc. I’d use a flat-response condenser-or in other words-a mic with no built-in frequency boosts (a PA system mic has a presence peak, usually built in at 4 or 5 K-to make a vocal kick through a PA). If you only have one mic-you want it to “hear” the sound only—not add things to it. A good lead vocal mic in the studio usually doesn’t need too much eq. It will also work fine on most anything else-if you are careful.
Generally, a LOUD electric guitar amp mic, in my opinion, should be a dynamic mic, as versed a more-sensitive condenser mic (mentioned above). A dynamic mic has a larger mass inside it to actually move with the sound. Less sensitive, but also less likely to be blown apart by LOUD sounds. It doesn’t need to be as sensitive in that position. A lot of times-the same thing applies for LOUD drums, such as tom toms. Plus-really you don’t want to “hear” other things nearby with that particular mic—just the thing you are actually recording. I also prefer flat response mics on these positions. Again, this is all subjective….
Until next time, have fun while learning to make music!
