I want a couple of cheap multi-pattern condensors for my 2-track singer/songwriter demo rig. One would be for vocals (mostly male), one for acoustic guitar. I want multi-pattern so that I can do the figure-8 null trick. I'm thinking of a Studio Projects C3 for vocals and a B3 for acoustic. Has anyone tried the CAD 179? How does it compare to the C3 and B3? Any other mic's I should be considering in that price range that work well for this kind of thing?
