You have ten posts now so you should be able to post links.
If you don't already have a means of hosting files, get a soundcloud account (or similar).
You can upload clips and post up links to them.
Did you try the 'wrong' side like I said, just incase someone's had it open and footered with it?
I might be wrong but I think it's possible to put the NT1a back together backwards.
Try both sides, and if that's no good record us a clip please.
As I understand it, the NT1000 is a slightly higher class of mic. Most people seem to prefer it over the nt1 or nt1a, but the nt1a is still a very usable mic.
I've found it to be very clear, bright and detailed.
It's not the kind of mic where you might think something's wrong, if you know what i mean.
