Geraldo ... A minority opinion, for sure, but the Rode mic's have always sounded "plasticky" or "transistorish" to me, though this is more apparent on some sources more than another. It's always very apparent to my ears on a piano from an octave above middle c on up. Even on sources such as a metal flute, there is this amp signature. To be fair, though, more people than not like the Rode mic's.
Agreed. I have two old NT5s and find them very unpleasant on (classical) acoustic gtr. They're for sale if anyone wants to pay to confirm this.
