OK, I wanted to make this answer short and sweet. But It can't. There are quite a few things that are not answered/specified here.
1. If the MP3 is broken, not the mic, the mic as a component should work.
2. Getting a Reading (does he mean sound out of an Amp or voltage?)
3. What is the mic used for? More importantly how?
4. Wheres a schematic/explanation of the mod/circuit...
5. This post was a long time ago (plz try not to bump
![:winker:](http://acidmods.com/forum/Smileys/default/bigwink.gif)
) and it seems like it doesn't need answered since larcerkev doesn't look very active.
I believe:
a. He heated the Mic up with his soldering iron and killed it by accident.
b. The Mic's Polarity is wrong
c. The pins has been soldered together (shorted)
d. no amplifier is being used; he hooked it right up to a speaker and expected it to work immediately like "Plug n Play".
