FOR: Recording instrumentalists and singers. The M-Four has all the presence and character expected in a tube mic, but its biggest draw is its ability to customize the perfect response pattern for whatever is being recorded. On top of the usual cardioid, omni- and bidirectional patterns, there are also six additional subtle stages between. So many options make it a breeze to dial in the best blend of signal and room. It nicely handles the grit in male voices and the bite of horns and percussion.
NOT FOR: The indecisive. The many choices may leave some second-guessing where the best sound lies.
