A guitar is different from most other musical instruments in that it can colour the sound, so it is essential that my guitars have ample possibilities for colouring the sound.

For me, a classical concert guitar has to have a sound that is inspiring for the player. To play music in an interesting and emotional way, the guitarist must be able to make a sufficient difference between playing soft and playing loud. So I try to make guitars with a wide dynamic range.

All the notes of a guitar have to be equal in strength. This is the only way to make it possible for the guitarist to do justice to the music he plays. So my guitars have to have strong trebles and rich basses.

Especially to make very short notes sound well, for example in a tremolo, the sound of the guitar has to come quickly. My guitars have to react quickly to the release of the string by the finger.

I find also that a guitar is much more satisfying to play when the notes have length. This is especially so for the trebles, which tend to be shorter in length than the basses.
