At first glance, it looks like a Shure Super 55... but, I don't think it is, there seems to be something different to back end of the mike they use that's not on the Shure Super 55.
I've looked for pics from CBM looking for better pics of their mic. While, there seem to be a couple pics with a back piece the looks a little thicker most of them sire look like a Shure Super 55 - I've even looked at my own multiple times. There's uses black screen - which I think the Super 55 with the switch comes with (as theirs appears to be in some pics). Even if it's not - these are customizable - I bought mine from Mutant Microphones and it's customized with a full warranty (different screen, different mic internals).
