For technical specifications, while t adj said. the body of the microphone is robust, comes with a storage case in the sky, a pair of pliers and a user manual, instructive when one knows there is not much at first, like me.

robust body, as the head, I do not really know what to think since it is not fixed (soda) to the body (the possibility to run on it even, part of which I can not understand the usefulness. microphone stand needed

OVERALL OPINION

I use it for a month by repeating the resumption of my guitar amp, but I had to dj at his recording sessions / concerts. I also had the opportunity to use a Sennheiser E609, and I must say that the SM57 has made me a better impression, rendering less "clinical", aseptic more raw, organic sound of friendly origin I find that the E609 .. not tried on other sound sources, j'diterai if necessary.

That said, it ncessite a microphone stand, while the sennheiser can be suspended via the grip of the amp.

as it is more cheaper than the Sennheiser, and as I am not a specialist in microphones in (meaning I have not tried 50), I would do this twice a choice plutt! APRS, be seen on the hard, but he seems cut out to be short-lived.
