Selected: Clarinet
A/D improvement
We offer two different A/D improvements that eliminate the stuffiness of the left-hand D. The most common is an alteration to the bore/tone-hole proportion. It is very efficient and doesn't require an extra key.

In rare circumstances, we can add an extra resonance key to overcome the stuffiness. It varies amongst clarinet models and is more common for German-style instruments. Both techniques will not have any negative side effects on the intonation.
