So , I decided to try D'Addario NYXL strings on my Alan Black built 'Carter'. Foolishly, instead of doing it 1 string at a time, I removed all of the strings
This resulted in some of my return springs popping loose and some of the pull rods jumping out, which is how I came to need replacement dog bones.
Now when trying to tune it I find that the B-C# raise on the fifth string will not return to pitch. It comes back a semitone sharp.
When I deploy the LKV B-Bb lower, it releases and returns to pitch.
What should I be looking for?
