Thank you for the prompt answer Martin!

I would ask you if in your experience it should work properly using 2 different diaphragm mics (large and small) or it should be better getting a pair mics Neumann ... My point is that I have found Shure KSM 44 a very good quality sound product but with a very slow response and this is not the best for flamenco as you can get by yourself. So what about using a slow and a fast response mics in a stereo system for recording my conde hermanos flamenco guitar?

Thank and Best Regards
