For many years there have been attempts by different guitar manufacturers to build guitars from thermally modified wood. So far, however, only thermally treated guitar tops have been manufactured. At Baton Rouge Guitars, we developed a process as part of a research project that makes it possible to build a complete guitar from thermo-optimized wood. The first two acoustic guitar models and a classic guitar model are now on the market:
During the manufacturing process, the wood is exposed to a minimum heat of 150° C for several hours. Different chemical remodeling processes are used to dry out the wood and make it very brittle. The secret is finding the exact ratio of heat to its duration in order to achieve the optimal degree of modification for every type of wood.
This is exactly why science is important as it enables us to reduce the error rate. At the same time, we can define criteria that are based on clear measured values. On the basis of numerous sound analysis, scientists have examined the vibration behaviours of native and modified wood and found that the right process can improve the acoustic properties of all types of wood for guitar making.
