主权项

1. A device for altering string tension on a stringed musical instrument, said instrument configured to suspend at least two strings in tension above a structure defining a body, said device configured to engage at least two said strings and comprising,
a first member moveable relative to a first base, and a second member moveable relative to a second member base, wherein each of said first and second members is configured to directly or indirectly engage each string of a first set comprising at least one string such that a said motion of said member relative to its respective base induces displacement relative to said base in the portion of said string engaged by said member, and further comprising a control lever configured to be rotated by a user about at least one control axis, wherein said lever is configured to directly or indirectly engage each of said first and second members, such that each of said first and second members is moveable simultaneously with the other relative to its respective base by said rotation of said lever, such that the tension in at least one string is altered to a degree substantially determined by the combination of said displacements caused by said simultaneous motion of said first and second members.
