Whatever you do, try not to buy a used Ribbon mic that you haven't had a chance to hear, esp next to another Ribbon mic, and then some mics that you consider standard. I'll tell you all damn day that ribbons are more robust than most people think, but they still do stretch/break. Royer includes the cost of one re-ribboning in with the purchase price. Pretty cool. And then again, even if you do rip it, its only like $100 from Stephan Sank or Wes Dooley to get it redone. I say use them on all the loud stuff, get great sounds, and if it breaks, just get it redone! It might not be an exact freqency match, but the ribbons sound killer, and this might sound weird saying, but they "hear" the same way that your ears do, IMO.
