.......a small tale about my SM58 dealing....Having bought this model online some years ago, I noticed it made a lot more handling noise onstage on the mic stand and did not sound as full than my older Shure mic. I investigated, found the Shure site saying what the weight ‘should’ be and sure enough the one I had bought was not the same weight, plus the wire coding was slightly different under the pop shield. Luckily I got my money back. However, I then bought a new Shure mic from a bona fide UK dealer and the weight was not what the Shure website stated. I called the UK distributor and they gave info that Shure change things a bit because they are one of, if not the most copied mic by the chinese and regularly get factories in china shut down that make the fakes. One way of dealing with it was to slightly change the properties of the mic in trying to keep a step ahead of the fake game and so, the problem is we are never quite sure of a Shure unless bought from a reputable dealer.
