Torrefied Ash Body Electric / Bass Guitar

Torrified Ash Wood has undergone a thermal process, this process modifies the intern structure of the wood by applying heat in an oxygen-free environment. The aging of the wood achieved by torrefaction process is similar to that achieved naturally oven the years. This process improves a better stability, decreases the capacity to absorb moisture, increases the speed of sound, decreases the weight of the wood, and it gives the wood a deep colour and enhances the wood grain. This heating process does not affect acoustic properties and is much appreciated by most luthiers.

 

Qualities resulting from torrefaction process application:

- Improves stability.

- Decreases the capacity to absorb moisture.

- Harden cell walls.

- The resins crystallize and partially evaporate.

- Increases stiffness (flexural strength).

- Cleans pore wood.

- Increases the speed of sound.

- Richer deep colour.

- Makes the weight lighter

 

Conclusion:

Torrefaction process does not transform worse quality wood into a better one, but it turns significantly good properties even better.
