Interesting concept. You made it look like a record with the design of my microphone, except, only I would know that. Font for my name was a little too plain and the white line going thru didn't give it the boldness I was looking for, but it was something different and somewhat considerable. I'd get rid of the circle graphic and stick with something more about my microphone, as well as entertain other suggestions above.
#62, 63, 64, 65 Not my style of microphone. Looks like a fan from far. I'm sorry if i gave you the impression that I liked the initial graphic. I thought it was interesting and understood what you were doing, but I also mentioned to "get rid of the circle graphic". Was worth a shot and was different than others.
#54, 55, 56 Are better, in my opinion. However, those are desk mics and I am not on radio. The microphone I suggested you work off of requires a mic stand which is what I typically use in my performances. It's also the mic I own and am known to use. Either way, I do like the font type and placement.
