I've mostly been using these mics for OH on drums. With the right placement you get a really good sound. I could enjoy the sound without any clos up mics, and still got a good overall mix of the drum sound.
The sound is rather transparent. If you got good instrument it will sound great. If the instrument is bad sounding, the soudn will be bad.
What goes in, comes out.
I would absolutely recommend these for anyone that needs a matched stereo-pair at a good pricepoint.
