I bought one of these mics, just to see what I could do with them. Most studios I've interned at had Shure gooseneck condensers on the toms, so I wanted to try this since it's much more affordable.
Needless to say, I'm completely blown away by this microphone! It's small, with a clamp that could crush a brick. It's made of metal and carbon fiber infused plastic so it's veeery sturdy. I was afraid that the gooseneck would bend down after a few hits on the drums it's clamped to, but nope, the mics stay stationary the whole time!
As for the sound, it's exactly what you'd expect from a small condenser mic. Fantastic top end clarity, very neutral and if placed well, you can enhance the low end pickup, but honestly it doesn't need it that much. This microphone is incredibly hard to get to sound bad.
My only gripe with the mic is that it picks up aloooot, of cymbal bleed, more so than most other gooseneck condensers I've used, but with the proper gating and processing, all that can be dealt with in a mix.
I now own 4 of these, and plan to get more eventually!
10/10 for the beyerdynamic TG D58c!
