The Nano Head eliminates many of these microphone problems instantly because it is at least 20 dB quieter than a 50 watt head, so that the volume levels coming from your speaker cabinet are very close to the levels that a loud singer can produce. The amp is capable of going into total saturation, struggling like crazy and sweating up a storm at this moderate volume, so no matter where you put the microphone it's safe signal level that won't overload your preamps or strain the microphone's element. The result is a crystal-clear reproduction of the speaker's sound. The other high-volume factors that can mess up your ears (there's something called the Fletcher-Munson curves that change the way your ears hear things at high volumes) are much reduced, too, so the characteristic of the sound you hear in the room will be much closer to the recorded sound. The first time I put a mic in front of my Orange 4X12 with greenbacks while it was connected to a Nano Head, I was stunned at how accurately the recording matched the tone of the cabinet on playback, and was delighted that I could set the mic position while wearing headphones in the same room and find the exact spot I wanted to capture. After 10 years working full-time as a recording engineer (my former job), this is one of the first times I've been able to get a great guitar tone on the first try. I have such painful memories of trying to capture huge tones and just failing miserably? gahh!
