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.
Regards Roger
