Update Jan 2021:Thanks. I will do that. I hope the support also works for Germany.
BTW: Is there any way to find out when the bass was built ? I can't find any serial# or build date.
Should have posted this earlier., I guess. After I contacted NS in Oct 2020 they told me that my bridge was an older design which had already been updated. They directed me to their Czech manufacturing site. Their quality manager sent me a complete new bridge free of charge. After installing the new bridge all tuning problems disappeared. Great customer support !
