This type of instrument construction features the guitar’s neck extending through the entire length of the body, effectively forming the central structural element. Instead of being bolted or glued on, the neck is a continuous piece of wood to which the body wings are attached. An example would be a build-it-yourself package allowing luthiers or hobbyists to create an instrument based on this design.
This design offers enhanced sustain and improved transfer of vibrational energy throughout the instrument, resulting in a richer, more resonant tone. This construction method has gained favor among players seeking instruments with exceptional stability, playability, and sustain. Historically, this construction technique was introduced to create more durable instruments but evolved to appeal for the sonic qualities it provides.
