Well, I already have the 2001. So is that a consideration? I bought it when I didn't know any better and really, I plan on buying an SM7 anyway.... but upgrading the 2001 would seem a no-brainer. Buying and upgrading the 990 is a whole 'nuther question since I don't have it.
Of course it would probably be cheaper and better to buy a Guage...

I have bought too many things with not enough information, like a ribbon mic not realizing it needs extra power of course that is easily fixed... but some things aren't.
Now I am realizing that if I want to layer vocals (or guitars) using a lower end condenser might not be a good option for layering or adding harmonies because of adding unwanted sibilance. If I understand correctly, a decent dynamic mic on top of the condenser will probably be better... or different condensers.... (trying to learn here without wasting too much money).
Thank you for the reply!
