The Shure 55S
The "Elvis Mic"
Shure Unidyne (unidirectional) Model 55S dynamic
microphone
Throughout his performing career Elvis sang through a
multitude of different types of microphones and, at least while touring
in the 1950s, was dependent on the venue to provide the PA system (see
the venues section).
Prior to Bill getting an amp, Scotty has said that when they would
arrive at a venue they would hope that there would be an additional
microphone to amplify Bill's bass, and that in some instances Elvis
would have to sing through the second input on Scotty's amp (though its
never been stated whether they traveled with a mic of their own).

No doubt through the popularity of a number of select
and widely distributed photographs, there is one microphone in
particular that through the years he has been "unofficially" associated
with and it has been quite often referred to by "the
uninformed" as "the Elvis mic."

That microphone is a Shure Unidyne 55S. It's not surprising
though, with its polished chrome look and its futuristic, for the time, stylized design,
it is one of the most readily identifiable microphones from an
era that saw the birth of a new form of music, one whose fans would dub
Elvis 'the king' of.

The Shure Brothers
got their start in the mid 1920s in Chicago selling radio parts kits and
by 1931 started developing their own microphones. They introduced
the Unidyne 55 in 1939 which, according
to Shure, was the first single-element unidirectional microphone. The
single-element design made microphones smaller, less expensive, and,
therefore, more accessible to all. Sam
Phillips used a Shure 556 Unidyne, among other mics, to record at
Sun. In 1951 Shure introduced
a smaller version of the renowned 55
called the Unidyne 55S
(and 55SW, a version with an on/off switch).1

Elvis' "presumed" association with that particular model, if it hadn't been
already, was likely sealed for all time in January of 1993 when the U.S. Postal
Service honored him with a commemorative stamp and for the artwork chose
a '50s era representation with an interpretation of a microphone like the Shure
models.

According to the Post Office, as of 2006, the 1993 Elvis stamp continued to
hold court as the most popular stamp of all time with more than 124
million collected. Although the Shure company no longer makes or
services this model, the do offer a
Series II. Though it looks like the old one in appearance, it is
in reality a contemporary design with modern elements. The parts are not
interchangeable with the old ones. Because of their abundance and
popularity at the time, there are a number of them out there that can
still be found.
My old, non functioning 55S, prior to refurbishing
I've had one for several years that I bought for $15 at
a vintage guitar show in Nashville when I was in town for Scotty's 50th
year with Gibson celebration party. Until recently,
it was
not working and only of ornamental value. I contacted Christopher Curry of
Mutant Mics,
who repairs and reconditions antique mics and can even upgrade ("hot
rod") them with lights and modern
elements such as Shure SM58's, Beta 58's and 87 Beta's. He specializes
in the Shure 55 series.

Chris told me he had a used dynamic
single coil cartridge, "cart" for short, in super
shape for the inside to bring it back to new again and would include a refurb:
cleaning inside and polishing the outside, new wires if needed, all new solder joints, and
a new connector if the one in there was in bad shape.

refurbishing
Ultimately, this mic required replacement of a few things other than the
cart... a couple of wires and the connector in the handle (it's screw
hole was stripped.). He also put a new spring in it since the old
one was corroded into the hole and wouldn't come out.

He also added a new foam screen since the old screen/silk was in worse shape
than thought, so it will still look original and have a slightly
better sound. The originals came in either red, blue and black, I
chose black. Unfortunately time didn't permit Chris to photograph
the work done on mine to display here but he did have the process
documented from a previous similar repair.

The HML impedence switch on the bottom rear of the 55S
The cord on mine is a vintage one with a 1/4" phono plug on the
end. It connects two of
the wires together and adds gain above normal... more chance for
feedback... also the M and L part of the HML switch to vary impedance
(high, medium and low) will not work.

To make that functional you need to have a cord with
a vintage connector on one end and a contemporary XLR on the
other. This will make the HML impedance switch work properly and be easier to handle feedback.
