my son is fan of Garageband on Mac, and the internal microphone found its limits for the guitar. First I bought a microphone, that did not work without an amp, brief disappointment. This solution, which transforms the output jack of the USB microphone is perfect. One branch and nothing else, it works perfectly. Combined with a quality microphone (70), a recording quality is obtained top (guitar, vocals). Of course, the microphone must have a XLR output otherwise it can not connect to the ICICLE. There are also all in one solution, but more expensive. And this type of microphone is not versatile (amp, turntable DJ ....). To view reliability over time but the simple solution is good!
