So I have a 10 year old loree. it’s been serviced a few times, had a crack repaired, nothing too unusual and generally I adjust it myself and can fix most things.

Recently I’ve had a problem with my A being very unstable. The tuning is actually fine but it really really wants to break into the upper octave and I have not been able to figure out what is going on. There has also been some response issues in my low register that I believe is related.

Is there something obvious I’m missing?
