The instrument making depends on the musician’s body type and uses two styles. The first is the Foustalieris style with a -67 scale, and the second is based on an old bulgari instrument with a -70 scale.
The types of wood that are used for a solid carved instrument are black mulberry tree (around 200 to 500 years old), local walnut tree, and other types of wood that the musician prefers.
The body with wooden components allows us to use ebony, rosewood, Brazilian rosewood, zirokote, venge, kokobolo, and other exotic wood types, as well as for the fingerboard.
For the neck I use walnut tree, mulberry tree, black mulberry tree, mahogany, sipo mahogany, linden wood, and a fingerboard.
The instrument keys are divided into two categories. The wooden keys are made of ebony or indian rosewood. The mechanical keys are a true imitation of the wooden keys in appearance and weight, with the exception of an internal mechanism with cogwheels that offers better control and precision in the tuning of the string.
For the neck I usually use fishing line, since the fets can move. Another option after custom order is copper wire, or steady fets. The copper wire also needs more frequent tuning due to the contraction and expansion from the temperature variation per season.
For the instrument decoration I use φίλντισι- seashell-άμπαλον- άμπαλον white-άμπαλον purle- semi-precious stones, ταρταρούγκα, φιλέτα και πυρογραφία on the top.
