Abstract: A string replacement assistance apparatus is used when the strings of a stringed instrument equipped with a tremolo unit are replaced. The tremolo unit makes a pivotal movement in arm-up and arm-down directions by an operation of a tremolo arm connected thereto. The string replacement assistance apparatus includes a base section which is to be put on the body of the stringed instrument and a holding section which is elongated from the base section and holds the tremolo arm to prevent the tremolo unit from the pivotal movement.

Abstract: The string securing apparatus for string instrument of this invention arranges a plurality of saddle-attaching members on the top face of a bridge base in correspondence with strings, and secures them to the bridge base so that they can be movably adjusted in the front-rear direction. A bridge saddle is attached to each saddle-attaching member so as to rotate up and down. The string is inserted through a pipe section in the bridge saddles and led above the bridge saddles by a lever attachment hole; the string is curved forward to a string supporting section. A cam lever is inserted in the lever attachment hole of the bridge saddles so as to freely rotate, and a spring presses the cam lever forward. A cam section of the cam lever pushes the string and secures it by tightening it to the string supporting section.

Abstract: A body structure of an electric guitar of a solid type is constituted by a body and a neck, which are firmly joined together using adhesive and/or bolts. An engagement hollow is formed over the entire length of the back of the body, and an extending portion is integrally extended from a base portion of the neck with a smoothly curved portion therebetween. The base portion of the neck is engaged with a rectangular hollow formed in the front end portion of the body, and the extending portion of the neck is engaged with the engagement hollow of the back of the body. An adhesive bank channel is formed in the periphery of the bottom of the engagement hollow to prevent an excess of adhesive from overflowing and dirtying the backs of the body and neck when joined together using adhesive.

Abstract: A tremolo mechanism is arranged on the body of an electric guitar and is constituted by a tremolo arm, a bridge base, and plural bridge saddles, wherein the bridge base has a roughly T-shape constituted by a plate that is arranged above the exterior surface of the body, and a string stopper that is received in a hollow space of the body. Herein, the bridge saddles are arranged on the upper surface of the plate that is curved approximately in a convex shape whose curvature substantially matches the curvature of a fingerboard of a neck curved in the width direction. In addition, the bridge saddles are interconnected with the bridge base by octave adjustment screws, which are arranged beneath the plate using a prescribed attachment portion arranged inside of the hollow space of the body.

Abstract: An electric stringed instrument has a frame body the contour of which is like the outline of a solid body of a corresponding electric or acoustic stringed instrument; the frame body is constituted by plural frame pieces, and the frame piece is detachably connected to a trunk of the electric stringed instrument; a user slings the electric stringed instrument over his or her shoulder by means of a strap so that the strap is to be connected to the trunk by means of fasteners; the fasteners are further used for securing the frame piece to the trunk so that the frame pieces are not unintentionally dropped out from the trunk without increasing the fasteners.

Abstract: A stringed instrument case comprises a case body and a cover, wherein an internal member made of a foam resin is arranged inside of the case body to form a storage hollow allowing a stringed instrument to be stored therein. A body fixing member for fixing a body of the stringed instrument at a prescribed position is arranged and adequately positioned in the storage hollow in response to the size of the body, and a neck fixing member having a plurality of neck reception portions each capable of receiving a tip end portion of a neck of the stringed instrument is arranged in the storage hollow with a prescribed distance apart from the body fixing member, wherein the neck fixing member can be adjusted in position in the longitudinal direction of the case body.

Abstract: An electric percussion unit and small-sized speakers are detachably connected to a trunk of an electric frame guitar, and a circuit board, on which electric circuit components required for generating tones and percussion sound are mounted, and a battery unit are housed in the trunk; while a guitarist is playing a flamenco on the electric frame guitar, the guitarist beats the percussion unit with his or her hand or finger nails, and the guitar tones and percussion sound are radiated from the small-sized speakers; the electric frame guitar system is available for a wide variety of music genres, and the portability is enhanced.

Abstract: In an attachment structure for attaching a neck to a guitar body, particularly an electric guitar body, a connecting portion is formed at a heel portion of the neck, and this connecting plate is engaged with an engagement recess formed in the backside of the guitar body and fastened in place by fastening screws. The pickup units are installed on the guitar body from the backside so as to positionally correspond to the connecting portion of the neck. One end of a balance spring is connected to the tremolo mechanism disposed on the guitar body and another end of the balance spring is connected to the connecting plate of the neck.

Abstract: A bonding structure is provided, which is capable of eliminating overflow of the adhesive to the outside of the body, and which is capable of eliminating generation of a shrinkage cavity. The cross-section of a rib member 10 is to have approximate H shaped cross section, which shape is formed by an internal flange 11 and an external flange 12, each connected by a web 13, and the plate members are adhered to the top and bottom surfaces 11A and 11B of the internal flange 11.

Abstract: A stringed instrument such as an electric guitar has a specially designed body structure, which is configured by a body frame, a center block, at least one bridge, a front board, a back board and a back cover. The bridge is arranged between a side portion of the body frame and a side wall of the center block, thus partitioning an interior space of the body frame to provide a vacant space for arranging electrical parts. Because of the provision of the bridge, it is possible to improve rigidity of the body structure. Herein, the vacant space is reduced in size and area, and it is encompassed by the side portion of the body frame, the side wall of the center block and the bridge. The front board is used to completely cover the front side of the body frame. The back board is partially cut out and is used to cover the back side of the body except for the opening area of the vacant space inside of the body frame.
