I have my eye on is the Octavamod MXL 603 Ultimate SDC mod: Award-winning microphone engineering from Michael Joly They sound great, and I know people who are very happy with these mods. Since I don't have any modded mics or any matched pairs I think this might be a good purchase. The question I have though is this: If a matched pair is handpicked from hundreds of microphones, and you mod both the mics by swapping out a couple parts, are they still a perfectly matched pair? My intuition tells me not. What do you guys think?
