I'm writing to all the guys whose designs I like so far. For yours, I still am not crazy about the font. I don't know what to suggest, though. Here's my overall comments. Not everything applies to yours, but you can use the ideas to keep coming up with stuff if you want. I like the logo on a black background. I like the "badge" idea. I like the int'l orange and brown. I like the LED meter bridge. I like the bridge-wire-as-mic-cable, but haven't seen "it" yet. Keep trying.
#7 - We keep coming back to that one. Got an Atari-like feel to it. Some of us are a little concerned the LED indicators are over-done, so we are cautious. But this is one we can't really shake yet. We're extending until Sunday, if you want to try something else.
