Subject: Re: Chord Mic

George,

Thanks for the great info. I was thinking that the set up would be useful
to
players and harp vocalists, who could mount any mic, including a wireless
to
the chest plate for mobility. I understand that the mic is discontinued,
but
do you know if the chest plates are available?

Thank you.

The mic is the now obsolete Shure 300, or 315 ribbon microphone. The

bodies of two mics are disected, then reconstructed and mounted on a WW2

Army Air Force chest microphone plate. There is no difference in frequency

response between the 300 and 315, however in their stand mounting

applications, the 300 has vibration isolator, whereas the 315 has an

optional on/off switch. The freq. response is 300-20,000. Shure made one

more ribbon microphone, and it was the 330, and its freq. response was

20-20,000. The internal design was essentially the same, but the body was

a little different and certainly was heavier. Like the 300, it too was

built with a vibration isolator for the stand application. For many years,

Johnny Carson used the 330, which was mounted to a desk stand and was

placed on his prop. Many harmonica players use the 330 to remake into

chest mic, however, they remain heavy.

The Shure corp. has obsoleted this line of mics about 15 years ago. To

find one would be like finding a dinosaur.

The closest online photo would be in Danny Wilson's photo of the

harmonicats in Omaha NE.
