In acoustic guitar construction there are several ways of joining neck and body. In electric guitars, and in particular solid body models, there is only one principal method (discounting neck-through construction) with two variations. A pocket is routed in the guitar body and the neck is either screwed or glued to the body.
The thickness of the guitar at the junction point is shared between the neck and the body, approximately 50% each.

Our butt joint method maintains almost full thickness of both neck and body at the junction point.
As the neck is twice the thickness in the region of the junction it is less subject to flexion caused by the pull of the strings.
The junction between neck and body is reinforced rather than stressed by string tension.
The transmission of energy between neck and body is optimal thus having no potential detrimental effect on the sustain of the instrument.
