While I know the AT 4050s are great mics - even though I've never used them myself - remember that your success tonight may not have resulted from the mics alone. Location, config, venue, sound system, mix, etc. all play a role. Perhaps everything just came together at once tonight to deliver outstanding results. I wish it happened more often! That said, if everything came together but the mics sucked, that would've been the pits. Great to hear you're digging the 4050s, Ray.
Don't keep us in suspense. What'd you record? With what pattern? Setup in what config? MP3 sample, perhaps?
