I build acoustic guitars according model Dreadnought 28. This model is characterized by the standard shape of the body and the head. I use classic materials like: spruce/rosewood/mahogany. Model D.28 is designed according to mensure 645.2 mm and the standard strings spacing. If you are interested, I am able to make a guitar from the other available materials and also adjust the neck profile (or string spacing) according to your specific requirements, beyond the any standards. In addition to standard procedures, I offer a different construction of the top: Lightening of the braces using CNC router and use the carbon-fiber profiles for reinforcing the braces.
Shapes of the neck:
