Neck making 2

This week, I did not have major progress for the neck making. I made a cavity for neck extension.This cavity is for the neck extension above 14th fret. My neck has two graphite rods along with an adjustable truss rod. Two graphite rods are sit all the way from 1fret to 22 fret. This extended graphite reinforcement improves sound quality particularly above 14th fret. Graphite reinforcement also improves neck's mechanical movement much first. As a result,  more over tones are generated from the super high responsible neck. Ultimately, a solid Graphite neck might be able to create much more over tones from bass to treble. However, this is no longer a traditional instrument. Using the Graphite rod might be a controversial subject against conventional guitar construction.
