Nope! SM 58 isch praktisch ds Gliche wie SM 57. Dr einzig Unterschied isch de Chorb, wobi dä natürli de Klang beiflusst.    Churze Uszug us dr Shure-Website:  The SM58 and SM57 do use the same cartridge. The grill, though, does effect the frequency response to some extent. At a distance, the difference is probably not noticable. But at  extremely close distances, the difference is noticeable. Due to the grill, a person's mouth can get closer to the diaphragm of an SM57, thus causing more proximity effect and increased bass when compared to the SM58.    Note that the cartridges are not interchangable because the mounting scheme is different for the two microphones.
