| 摘要 |
A tuning apparatus for a musical instrument is provided. The apparatus includes a clamp, a plurality of string-contacting members, and a string-contacting member spacing adjustment mechanism. The clamp removably attaches to a desired longitudinal position on the instrument's neck. Each member is rotatably supported by the clamp and rotates thereon independently of the other members. Each member also adjustably impinges upon and urges a given string or course thereof on the instrument toward a user-selectable one of three different longitudinal positions on the neck's front surface, these positions including a home position, a home−1 position, and a home+1 position. The mechanism allows a user to adjust the location of the members as a group on the clamp so as to substantially center the plane of rotation of each member over a different string or course thereof, and to maintain substantially equal spacing between each different adjacent pair of members. |

1. A tuning apparatus for a musical instrument comprising an elongated neck comprising a front surface over which a plurality of strings is stretched, comprising:
a clamp which is adapted to removably attach to a desired longitudinal position on the neck; a plurality of string-contacting members,
each of the string-contacting members being rotatably supported by the clamp,each of the string-contacting members being adapted to rotate on the clamp independently of the other string-contacting members, said rotation occurring along a plane that is substantially perpendicular to the front surface of the neck, andeach of the string-contacting members also being adapted to adjustably impinge upon and urge either a given string or course of strings toward a user-selectable one of three different longitudinal positions on said front surface, said positions comprising a home position, a home−1 position that is closer to a headstock end of the neck than the home position, and a home+1 position that is farther from the headstock end of the neck than the home position; and a string-contacting member spacing adjustment mechanism which is adapted to allow a user to slidably adjust the location of the string-contacting members as a group on the clamp so as to substantially center the plane of rotation of each of the string-contacting members over a different string or course of strings, and to maintain substantially equal spacing between each different adjacent pair of string-contacting members. |
