Subject: Re: Chord Mic

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.
