Okay, I got two of them today, thanks to Getuhgrip, and I tried them out tonight. Two things: they have a bit of self noise which you can hear when miking acoustic guitar; second, they have no proximity effect no matter which way you point them, which is pretty cool for miking acoustic guitar. I can pick up all the bottom end of the guitar without having to cut any of it to get rid of boominess. I'm not used to the relatively darker sound I'm hearing, but it's quite nice. One thing that's interesting: listening to the acoustic through the Behringers, I realize just how much bottom end I've been cutting when recording it through a condenser - more than I'd thought.
