Ten-string guitar prototype, ESTHAUG DIX, Model S18 No.61, Scale length of 650mm. Year 2023.


This guitar is designed around the Esthaug shape (Augmented Aesthetic) originating from a long process of dimensional research in its profile drawing, using the Golden Ratio.

Soundboard in spruce (year 1998) of the highest quality - Its bracing is made entirely of spruce taken from a very old soundboard of an old Pleyel piano.

It is designed according to a Lattice concept that could fit into a fractal system, composed in total of 117 glued and laminated pieces of wood in multiple layers, a pre-tensioning work established in the shape mold of the top, all meticulously sculpted-refined into a trapezoidal shape. It’s a kind of spring. The rest of the components are also made of aged spruce, including two mouth bars, reinforcements under the rosette and under the fingerboard, all glued in the mold then sculpted.

For the ebony components of this instrument, the ebony is of the highest choice from a vintage stock, certainly estimated to be over 50 years old. The stability of this wood and its fineness are exceptional.


*Rosette made of an ebony circle, filled in its center with a series of Alphanumeric motifs (white in maple, black in stained linden) to designate this instrument, interspersed with a diamond pattern made of stained maple.
*The top edge binding is made of maple and stained linden veneers constructed in one piece to eliminate a joint at the bottom of the body.
*The side edge bindings are made of ebony associated with a small red strip then base stained linden.
*The neck heel is ovoid shaped, made of an ebony block (matched with the bindings) associated with two red and black veneers to align well with the side edge binding.
*The bottom side join binding is made of ebony and red and black veneers.
*The body (back and sides) is made of top-quality Indian Rosewood (CITES OK)
*Side system composed of a multiple assortment of woods, assembled and glued in a mold representing the profile of the instrument.
Composition: Indian Rosewood, linden, balsa, ash plates for the molded block in three layers at the bottom-side join, molded in multiple layers for the "Soundhole" section on the left shoulder, A counter side in linden table side adds a contact surface to increase the width and thus the gluing surface. The visible interior of this composition is made of a very long red-stained maple veneer (One whole piece).
*The back of the instrument is Indian Rosewood The four back bars are made in three layers of very old Sapele mahogany (spring) The internal back strip is composed of four layers glued in a longitudinal shape mold in linden-red maple-linden-red maple, structurally glued in a longitudinal shape mold. An external median strip is composed of ebony and two red and black stained linden veneers.
*The neck is made of Honduras Cedar (CITES OK), heel block as well.
It is sculpted according to an asymmetrical profile to facilitate playing when using the first 6 strings like on a standard classical guitar.
Made of two standard necks glued together medially along the length to accommodate the unusual width of this model.
Reinforced with three longitudinally embedded carbon rods and receiving a maple strip (2mm) in position under the fingerboard (offset to increase tension holding) The head (characteristic design of Lahoun guitars with its small round mirror piece at the top of the head, Golden Ratio for its drawing) receives a three-part plate, ebony-red linden-ebony.
*The very thick lower plate ensures perfect resistance and is advanced on the neck to form the base of the nut groove, providing an all-ebony housing for this small bone piece.
*Tuning machines custom-made by ALESSI, with a 32mm cylinder spacing.
*The fingerboard is ebony.
*The bridge is ebony, its tailpiece is fitted with a bone frame enhanced by a small black-red-black strip. Its nut is bone.
