** SM57s and 58s, like most dynamic mics, have a close fitting cover over the diaphragm. There is a dome in the centre and a few small holes surrounding it - it protects the diaphragm but has another purpose.
Known as a "resonator cap" it creates a peak in the high frequency response above where it otherwise would be falling away.
The 58 uses a different cap to the 57, boosting response around 10 to 12 kHz by a few dB.

A boost sufficient to make the 58 sound particularly nasty of some
sources. But equal just fine on others.
But on a bad source one usually has often gone to something completely
different, rather than trying a 57 instead ...
