I test an Aurycle kit microphone (a u47 clone, all stock), the Austin ribbon kit (with Cinemag transformer), a Rode NT1-A, and an AKG C12-A.

They all go through the preamps on a Focusrite 18i20. I lined them up with a bit of distance from the guitar just so they shouldn't sound terribly different from one another just due to the positioning.
It's virtually impossible to do a real blind A/B comparison, so I generally don't even try. But there are some clear differences betwixt each of these mics.
