I didn't wan to mention the name of the company, but you guys seemed to figure it out. As far as the sound in between the drop outs, it's hard to say. I was at NAMM, and using unfamiliar headphones. All I could tell was that it was not too spitty on the dual backplate capsules.
I was a little annoyed with the owner of the company, though. If there's anything that drives me nuts, it's people who don't know about their product. I found out that the mic was solid state, so I asked him if its transformer less. He said yes. I followed up with asking which FET he's using. "Trade secret." OK, then can you tell me how you're converting the capsule impedance? Is it an emitter follower? "That's a trade secret, but if you want to buy one and open it up, you're welcome to."
"Trade secret" is usually trade show speak for "I have no idea what I'm talking about." I went through this with the Inner Tube folks a few years back, and they became hostile when I started asking technical questions they couldn't answer. Just say, "Somebody else designed the circuit for me, and he's not here to answer your questions."
