from what I understand, they don't require any phantom power... so you just plug it into your interface and DON'T switch on the 48v???
I may consider a tube mic when I upgrade next... I'm leanin' toward a Baby Bottle, though it's not a tube... but the few tube mics I've heard, all AT's, sounded real sexy...
so, what are the pros and cons of a tube??? and is there any special care that needs to be taken with them???
