I also remember taht Alembic uses wood that is not harvested, it is wood from trees that became available by natural cause: storm, age, soil instability, hurricane Etc ... .
Mica said once that although the wood for the guitars and basses are relatively old the guitar is always new! It will always take some time before the wood realizes it is a guitar and not a tree anymore!
Bonnie is more and more stabilizing now (I got her in 1996).

PS: you can start panicking when there are growing roots out of your upper horn, or a shoot on your headstock.
