I've got a Shure SM57 that appears to have lost a great deal of sensitivity. For the longest time I couldn't figure out the issue and was changing preamps, cables, gain staging, etc. But I recently was attempting to mic a source with the 57 and had the gain cranked and still hardly any input, then immediately (on the exact same cable and line) swapped the 57 for a 58 and was getting a hot input level.
So I can only assume the 57 is roasted. Is this a problem anyone else has experienced? Is it repairable? Shure charges nearly the cost of a used 57 to make a repair so I'm not doing that.
Thanks for any input (umm, no pun intended).
