Eh?I actually preferred the Shure, but was too late to vote
None.Rather interestingly you used a Shure SM58 and not the 57, which is billed as the instrument mike, what differences between the two, if any, do you see?
Before Christmas I was doing a little teaching, in one session I was covering microphones and post production sound, so I dug out my old tube driven tone generator and did the mad old science teacher bit. I don't think anyone in the class could hear much beyond 15kHz! Either that or the speakers couldn't reproduce much sound over 14.5kHz.None.
The only differences are the grill, which is supposed to have alight effect at around 13 kHz, which is too high for me to hear.
I did. Luckily there are always new products on the market.
