Abstract
Abstract A metal surface electric guitar is described which incorporates a metal plate attached to the solid body of the electric guitar, this plate overlying a hollow area in the body beneath the strings of the guitar. At least one electric pickup is attached to the portion of the plate over the hollow area in the solid body. Thus, the electrical signal produced by this pickup includes both components produced by the vibrating strings and components produced as a result of the resonance of the metal plate over the hollow area, this combination producing a unique sound. While the pickup may be positioned between the plate and the strings, it also may be located within the hollow area of the body if desired.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
194 words
An electric guitar including a solid body, a neck attached to the solid body, a bridge resting on the body portion, a plurality of steel strings attached to the neck and extending across the neck and bridge on the body, means attaching the strings to the solid body, and at least one electric pickup attached to the guitar and positioned to respond to the vibrations of the steel strings to produce a corresponding electric signal, the improvement comprising: (a) a hollow area in the body underlying the strings, the hollow area being substantially larger in lateral and longitudinal dimensions than the electric pickup, (b) a metal plate attached to the body and covering the hollow area, the thickness of the metal plate and the size of the hollow area being such that the plate resonates to vibrations of the steel strings, (c) means attaching the pickup to the guitar with the pickup being positioned relative to the hollow area at a location of appreciable vibrations of the metal plate, whereby vibrations of the strings induce vibrations in the metal plate over the hollow area, which vibrations modulate the electric signal produced by the pickup.
Claim 2
Dependent Claim
194 words
An electric guitar including a solid body, a neck attached to the solid body, a bridge resting on the body portion, a plurality of steel strings attached to the neck and extending across the neck and bridge on the body, means attaching the strings to the solid body, and at least one electric pickup attached to the guitar and positioned to respond to the vibrations of the steel strings to produce a corresponding electric signal, the improvement comprising: (a) a hollow area in the body underlying the strings, the hollow area being substantially larger in lateral and longitudinal dimensions than the electric pickup, (b) a metal plate attached to the body and covering the hollow area, the thickness of the metal plate and the size of the hollow area being such that the plate resonates to vibrations of the steel strings, (c) means attaching the pickup to the guitar with the pickup being positioned relative to the hollow area at a location of appreciable vibrations of the metal plate, whereby vibrations of the strings induce vibrations in the metal plate over the hollow area, which vibrations modulate the electric signal produced by the pickup.
Claim 3
Dependent Claim
56 words
An electric guitar as set forth in claim 1 in which the hollow area underlies and extends from the bridge to adjacent the neck, the metal plate covering the hollow area, the guitar including a plurality of electric pickups, the pickups being attached to the metal plate, each over the hollow area and underlying the strings.
Claim 4
Dependent Claim
77 words
An electric guitar as set forth in claim 1 including a plurality of pickups, said attachment means attaching each pickup to the guitar at a position relative to the hollow area at a location of appreciable vibrations of the metal plate, a dampening block in the hollow area bearing on both the metal plate and the solid body and being positioned between adjacent pickups to assist in separating and isolating the tonal qualities produced by the pickups.
Claim 5
Dependent Claim
27 words
An electric guitar as set forth in claim 1 in which the electric pickup is attached to the plate and positioned between the plate and the strings.
Claim 6
Dependent Claim
25 words
An electric guitar as set forth in claim 1 in which the pickup is positioned in the hollow area between the plate and the body.
Claim 7
Dependent Claim
44 words
An electric guitar as set forth in claim 1 in which the metal plate includes an opening over the hollow area and in which the pickup includes a pole piece projecting through the opening in the metal plate to a position adjacent the strings.
Claim 8
Dependent Claim
43 words
An electric guitar as set forth in claim 1 in which the pickup includes a pole piece which underlies the metal plate and senses the vibrations of the metal plate, the plate being formed of a material which will effect a magnetic field.
Claim 9
Dependent Claim
81 words
An electric guitar as set forth in claim 1 in which the hollow area underlies the strings and extends from adjacent to the neck to and beyond the bridge, the metal plate overlying all of the hollow area, the bridge bearing on the metal plate, the pickup being attached to the solid body of the guitar and positioned to underly the plate and sense vibrations in the plate, the plate being formed of a material which will effect a magnetic field.
Claim 10
Dependent Claim
55 words
An electric guitar as set forth in claim 8 including a plurality of pickups each underlying the strings, and a dampening block in the hollow area bearing on both the metal plate and the solid body and being positioned between adjacent pickups to assist in separating and isolating the tonal qualities produced by the pickups.
Claim 11
Dependent Claim
35 words
An electric guitar as set forth in claim 1 in which the bridge is positioned to rest upon the metal plate, the vibrations of the strings being transmitted through the bridge to the metal plate.
