This could be anything from a defective mic to a dirty pot in the
rig.
The easiest way to make this determination is by like/kind substitution.
Connect the suspect mic to another rig -- or connect a known good mic to
the rig in question.
Otherwise, you're spending money to fix/replace a mic that may not
even be defective.
Just a thought!
