Right now everything is in the "embrionic" stages. I was hoping to be further along, but in China they have a 3 week holiday.? I want to copyrite (spelling?) the designs so there will be no disputes from the big guys. Lundahl and Cinimag have been unbelivably supportive. These mics are like when you get a small box of crayons, you get the primary colors ie C-12, 47's, 67's, 87's, 251's etc. and these mics are like the big box with a lot of different colors. Nothing special, just different.
