The curved headstock 

The head of my steel string guitars is curved. It does not only stand out as a design feature but facilitates to operate the tuners.

The Heel 

To make the heels appearance more plastic it has a nice chamfer on it's edge. 

The elevated fingerboard 

The elevated fingerboard makes it easier for the player to reach the upper frets. It also changes the string angle in realation to the top: This "refines" the sound of the instrument.
