In
1925, the engineers at the Western Electric Company invented the "ring
and spring" electric microphone, ushering in the electrical age of
recording by replacing the low-fidelity acoustic systems that had been
in use during the early days of sound recording. This new technology
would revolutionize both the recording and radio broadcast industries.

Fast
forward 75 years, our family band, The Homegrown String Band™,
recorded our first CD in a modern digital recording studio. Then in
2012, my wife and I took a step back in time when we were invited by the
National Parks Department to participate in a recording session that
would take place at The Thomas Edison National Historic Park in West
Orange, New Jersey.
The antique Edison recording system we would
be using consisted of a horn with a diaphragm on the narrow end, a
needle, and a rotating wax cylinder. The sound waves coming into the
horn make the diaphragm vibrate, which in turn causes the needle to etch
a pattern onto the spinning wax disc. The playback system works the
same way in reverse. The rotating cylinder causes the needle to vibrate
the diaphragm, which reverts the vibrations to audible sound waves. Most
of the early recordings using systems like this were made by brass
bands, blues shouters, opera singers, and other acts that had enough
volume to get that needle vibrating strongly enough to make a good
impression in the wax-coated cylinder.
The first band to record
at our session was a brass band that played Sousa marches and the like.
They positioned themselves about ten feet away from the sound-capturing
horn and easily made several successful recordings. When it was our turn
to record, we chose two songs originally recorded by early commercial
country artists: "The Nine Pound Hammer,” originally recorded in 1927 by
Al Hopkins and the Hillbillies; and "How Many Biscuits Can You Eat,"
recorded by Grand Ole Opry stars Dr. Humphrey Bate and His Possum
Hunters. We soon discovered that the only way to make our stringed
instruments create enough air movement to get that needle to vibrate
sufficiently was to stand about a foot away from the horn. I actually
had to stick my head into the horn when I sang.
In 2019, we
purchased “Myrtle” from Ear Trumpet Labs in Portland, Oregon. The Myrtle
is a large diaphragm condenser microphone modeled after the Western
Electric spring and ring microphones of the late 1920s. Since then, we
have used Myrtle for live shows, Zoom shows, and our live mono field
recordings. The old-school single mic set-up gives us the look, feel,
and sound of the music recorded during the golden age of country music
between 1925 and 1931.
