The SM-57 and SM-58 have the same capsule inside, but sound totally
different.
I find the SM-58 dull because of the foam ball, but the SM-57 is a
remarkably useful mike.



I know this has been discussed in length, but in your opinion would taking
the foam out of a 58 make it a 57 (outside of the physical design)?



** 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.
