Dear all.
I record classical guitar with a pair of KM184. These are excellent mics but I lack some depth in my recordings. I'm considering the mid-side technique as an option. For this I need a good cardiod which I already have in one of my KM184.
I also need a fig 8 microphone and this is where I need advices.
Which of the Neumanns would you recommend for the purpose?
I've been told that microphones with several characteristics like omni, fig 8 and cardiod in the same mic aren't "real" characters. Is this true?

Kind regards
