When Should a Pinblock Be Replaced?
The pinblock is one of the key structural components that directly affects the tuning stability of a piano or grand piano.
Replacement is recommended when:
- the instrument no longer holds its tuning for long periods,
- the tuning pin holes have become enlarged or damaged,
- cracks appear within the pinblock wood.
