<P>PROBLEM TO BE SOLVED: To solve the following problem that the conventional electric guitar cannot be changed from one kind of guitar to another kind of guitar with a different function, and in order to manufacture various kinds of guitars with different functions, the manufacturing processes become complex, and the manufacturing costs become high. <P>SOLUTION: According to this invention, since a 1st group of parts for a string vibration system is mounted on a lower case and a 2nd group of parts of which the operation may be made unstable by vibrations is mounted on an upper case, the string vibrations of the 1st group of parts are made resistant to propagating to the 2nd group of parts at the time of performance, and is made resistant to being influenced by the string vibrations, and also since the upper case is made replaceable with another upper case mounted with a 2nd group of parts with a different function, it is made possible to easily obtain a string instrument with a new function by leaving the lower case mounted with a fundamental group of parts as a guitar mounted thereon as it is, but replacing only the upper case with another upper case mounted with the 2nd group of parts having another function. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
