    I've got a new SM58 which is made in Mexico. Appearantly it sounds quite
    different to another SM58 of mine which is made is USA. Both of them are
    2nd mic, so it could be a 2nd hand issue, but I just wondering if it'd sound
    differently if the location is different.

    The Mexico one sounds quite muddy and less spark as compare to the USA

    just wondering...

    I believe all 57 and 58 mics are mexican made now, have been for years
    and years

    HI George,

    Thanks for your quick reply. But do u know if they'd sound differently?

    thanks again.

    One of both of the mics might be broken. The pop filter(s) might be full of

  5. I havent notice two working 58 sounding all that diffrent where it would
    cause problems
    if one sounds"thin" it most likely is damaged

    It probably also sounds different than another SM58 that's made in
    either place. And so will your American made one. Get 50 of each and
    maybe you'll see a trend, or maybe not.
    Easily. One that's been spit in or dropped will sound different from
    one that has had reasonable care and handling, regardless of where
    it's made.

    Thanks everyone for dropping me the hints.

    In fact the guy sold me the Mexico SM58 has a few of them, so I will go for
    an exchange... too bad that he doesn't offer onsite test.

    Will see it soon if another one sounds better...

    No, your ears are fine! The old Unidyne III 57's and 58's do sound
    much better, clearer with more top end details than the Mexican
    57's/58's. I noticed this in the early 90's and since sold off the
    Mexicans and have collected the USA's.
    I once spoke to a Shure engineer about the quality change and he
    said that the stampers for the mylar diaphrams were not changed when
    the manufacturing went south (pun intended). Reminded me what happened
    to record pressing when the stampers were left in too long. If you
    don't hear the difference, good for you! A career in video is calling
    you. If you do, start collecting Unidyne III's. Another NAFTA success
    story. Guess when Ross Perot warned about that giant sucking sound, I
    didn't think he was describing the quality of Shure's mics.

    There should not be any substancial difference between elements made
    in the USA versus Mexico. They are made to the same tolorence and
    tested to insure the microphones meet the SM-58 spec. All quanlity
    control testing is done in Evanston. Large numbers of Mexico run mics
    are sent to be Q.C ed there.

    The test department has its own anachroic chamber and has about 6
    technicians running tests. Typically about 24-48 mics will be
    evaluated from a production run. If the mics fail, then the whole run
    is tossed.

    SM-58s can lead a tough life. A lot of things can change the sound of
    a mic. Take a look at the grill. Try removing the grill and comparing
    the mics again.

    Maybe someone from Shure can comment on whether "aging" of the element
    materials can shift the sonic characteristics around.

  10. or instead of looking for working ancient unidynes you might just try buying
    good new mics
    the 589any incarnation, built any where) is about the worst mic considered
    "industry standard" for just about any use

    got a chance to replace another used one (Mex), the same problem presists,
    so I guess the manufacturing place does make a different.

  13. I ran pink noise into my analizer, used 58 to "listen" to it and could find
    no diffrence in my USA or Mexican made 58's
    my listening tests found no diffrence
    these are well used mics so possible they have both been subjected to the
    same conditions so long as diffrence was assimilated years ago

    You will have better results if you use the mics on music, not noise.
    Mic pre's, cables, monitoring all have an effect. I was able to easily
    hear the difference between about a dozen or so Unidyne III's and
    Mexi-57's through the headphone outs of an 80's vintage fostex 4 buss
    mixer, not exactly stellar sonics, if you know what I mean...

  15. I wanted a quantitave thing I could point to and say--THERE is the
    diffrence, not just my subjective reaction, which produced nothing
