I recently conducted a small mic comparison with several different chromatic harmonicas. The mics are kinda not what I would have liked to have but they'll do for now until I get my close-miked session underway. I would have loved to test out an SM7 & maybe some ribbons but oh well. Keep in mind that a chromatic is not a diatonic and the players really have no desire to have a overdriven sound. A person playing some Mozart stuff can't do it with a diatonic but can with a chromatic. My first time doing this, so go easy. This really is alot of work and now I have a new appreciation for the fellas who do this kinda stuff. http://slidemeister.com/media/mic-test-1/mic-test.html The dynamic mics: AT 814a Audix OM-2 Audix i5 The condensers: Rode K2 CAD E-100 Oktava MK012 Mackie 400F was used for preamp & conversion.
