Is the SM58 really unbreakable?

I record a small group live in my basement and use a Shure sm58 for lead vocals. I've noticed that it's not nearly as "loud" as other dynamics I use...meaning, I have to turn the gain and trim up (and then get clipping when things rock) to get it to come through near 0.



The question is...can the sm58 break, get old, wear out, etc? I bought my lead one used and it shows lots of wear, can it be damaged enough to be less "powerful"? How would I tell if something is wrong with my 58?



Thanks!

An SM57/SM58 is really hard to break. It can be done. However...



I have been in sound crews that dropped 57's into the bells of tenor and bari saxophones and at the end of the night just picked them out cord and all-dripping condensation-and hung them on the wall to dry out. Next night, same routine. Very rugged and reliable.



I'm sure this vid was posted before but here it is again.

They are not unbreakable, but ridiculously close. I've repaired several that have been hammered into the floor when a mic stand tips over. The capsule survives, but the fine internal wiring can break when the capsule travels too far in it's rubber shockmount. Or rarely, the transformer gets dislodged and breaks a wire. I've seen the foam inside the windscreen deteriorate from old-age, but I think I've only ever seen one bad diaphragm.



My SM58 anecdote:

Our lead singer dropped his in the snow somewhere between the practice room and the truck in November. We found it 4 months later stomped into the mud after the snow melted in March. 18 years later that mic still works. A little rust around the grill, but still sounds A-Ok.

You should borrow another one and A/B them. I've never broken any of the dozen I've owned or been in charge of at the church over the last ten years. Many have been dropped and have dented windscreens, but I don't think there is any audible difference. Long ago I saw some that had broken wires (as dvdhawk says) but I don't really any with degraded sound - intermittent or off, but not degraded.



They are not the hottest mic in the world, but most mixer preamps have plenty of juice for them. What other dynamics are you comparing them to? How high are putting the trim?
