Even wood as stable as grenadilla breathes and moves. It will absorb and release moisture for decades.
In stabilizing grenadilla, it should be allowed to "settle" and lose its moisture slowly, under the most carefully controlled conditions. This process can either be done through a slow aging process or with modern industrialized drying techniques.
Contrary to common belief, the aged wood does not prove to be more stable than the artificially dried one. Before an instrument can be made, the wood needs to be dried to a humidity level of 6% to guarantee a proper fitting of the mechanism. It makes no difference if this is achieved over time or through artificial drying.
The production mistakes we see the most are chipped or deformed tone holes. If you have issues with intonation or voicing read more
