  Hi Torn,
                If the strings are seated and the bridge pins are =
secure.  Then lift the strings on both sides of the capo. After  lifting =
then make sure the hammer fitting is still good.
  If it is an isolated note. Check the hammer flange centre pin.   Trust =
me there is more weak trebles out there, caused by poor pinning, than we =
would care to count.

    P.S.
    It's most noticeable from playing the 3 string unisons
