I picked up a Rode NT1A recently at Guitar Center for $175 (talked 'em down from $199). An absolutley amazing-sounding mic for the money. My recordings have never sounded more professional.
Hrm I guess I like the NTK better cause it is a bit warmer. Perhaps I have recording the fiddle in the back of my mind.. cause the more I listen to the NT1-A, I like it.. it is a pretty clean mic heh.
I have both, and find the RODE to be a better sounding mic- clear as a bell, very versitle, and it stands out in the mix more than the 30305 IMO. Walter
