ABSTRACT:
BACKGROUND—FIELD OF INVENTION
The present invention relates to stringed musical instrument construction, and more specifically to an improved construction for a guitar, or similar instrument.
BACKGROUND—DESCRIPTION OF PRIOR ART
It is the usual practice to construct various portions of guitars separately and to join such separate portions in assembling the finished instrument. Joints between the neck and body are of the following types:
1. The neck is glued onto the body.
2. The neck is bolted onto the body.
3. The neck is glued and bolted onto the body. Also, the neck may extend the length of the instrument while having portions of the body glued onto the sides of the neck.
Since the tonal quality and other factors concerned with optimum sound output are to some extent dependent upon the structural integrity of the instrument, there is inevitably some loss in quality due to the fact that various portions of the instrument, though permanently assembled, are actually separate pieces. There is also the possibility that, although initially joined in a secure manner, the formed portions may become loose or detached.
Patents have been granted for unitary guitar construction. However, these guitars are formed from plastic and metal. The unitary guitar construction in U.S. Pat. No. 4,359,923 to Brunet, Nov. 23, 1982 is formed of aluminum. The unitary guitar construction in U.S. Pat. No. 4,088,050 to Appel, May 9, 1978 is formed from plastic. Due to its resonance properties, wood is the general and preferred material that guitars or like instruments are made of.
OBJECTS AND ADVANTAGES
Discontinuities in the instrument vibrations are caused by attaching the neck to the body of the instrument by:
1. Gluing.
2. Bolting.
3. Gluing and bolting. as well as the neck through the body design.
The current invention solves the problem of the neck/body joint by making the neck and body as one piece of wood.
It is a principal object of the present invention to provide a novel and improved construction for a guitar, or similar stringed instrument, which has superior sound qualities.
A further object is to provide a guitar, or the like, having both neck and body which are formed integrally, thereby improving the sustain of string vibration.
This invention avoids the neck/body joint, thus allowing a continuity of induced vibrations produced in the instrument. Still further objects and advantages will become apparent from a consideration of the ensuing description and drawing.
