I've been buying up used CAD M179 mics to mic my toms. I have two already and need one more. I ran across an ad in a local Craigslist for the CAD M-39. I'm not familiar with this one. Apparently, it's supposed to be a rebadged M179 that CAD made exclusively for Guitar Center. The didn't sell very well so CAD went with just the M179. The guy is asking $95 OBO. That's an okay deal for an M179 but feel like it should be less for the M39. They're just not that popular. Anyone have any experience with this mic?
