Whilst it is possible to make a reasonable guitar from average quality materials, it is impossible to make a good or excellent guitar without very high quality materials and the techniques to use them well. A good soundboard is absolutely essential to a good instrument:

The wood is cut in the best way possible by doing it himself; he has a wide choice within a range of excellent material from which to select the soundboard for a guitar.

Only matured european spruce (picea excelsa) is used and which has been drying for a minimum of twenty years for the concert model and for a minimum of five years but more usually ten years for the student model of instrument.

The consistency and quality of the materials of the ribs and back also influences the instruments timbre, stability and structural soundness throughout its life. Material which has been allowed to remain in the plank or wedge for a longer time is likely to be more stable than recently cut material.

The rosewood used for concert instruments has generally aged for between fifteen and thirty years of age and is therefore considerably better than most commercially available material. Alternative materials for ribs and backs are also available and all are stored at controlled humidity to ensure that they can be as stable as possible before use.
The range of stock materials is very large and the guitars can be both highly attractive and individual.
