I own a pair of AKG C1000s and I have used them extensively in the studio. They're a great set (I would recommend getting a pair) of small-diaphragm condensers. It has an on/off switch, which always comes in handy and the design of the mic makes it easy to set up and to place. The sound these things reproduce are great for all types of applications but mostly for acoustic instruments.

OVERALL OPINION

I've had these for about a year now but I had used them in studios in the past. I ended up buying a pair because they are cheap and are a great option to have for overheads, or miking individual cymbals. They have a great high end to them and are a great value for the price. Many times you can find them cheaper as a pair. I also have a pair of Rode NT5s that I use as another option for overheads. Compared to those I feel the C1000s are a little better suited for hi-hats or ride cymbals rather than general overheads like the NT5s or the Neumann KM184s. They are also great on vocals, especially on choirs or a group of singers. While these may not be my go to mics, I'm happy to have them in my arsenal as an option for things where the high end of it is important.
