How do you fix a squeaking bagpipe reed?

To fix a squeaking bagpipe reed, first ensure that the reed is properly seated in the chanter and that it is not overly tight. If the squeaking persists, check for moisture buildup and allow the reed to dry, as excess moisture can cause squeaking. You can also gently adjust the blades of the reed by sanding them lightly or using a small tool to tweak their position for better alignment. If the issue continues, consider replacing the reed, as it might be damaged or worn out.
