Abstract
A support for defining an end point of the vibrating portion of the strings of a stringed musical instrument comprises a base having a slot with walls which converge to an apex line. At least one rocker has walls which converge to a knife edge complementary to the apex line, where the angle between the walls of the base is larger than the angle between the walls of the rocker to allow the rocker to rock in the slot while the knife edge engages the apex line. The rocker has an arc-shaped surface centered at the knife edge for contacting at least one of the strings and moving with the string in a direction along the length of the string while maintaining the end point of the vibrating position of the string at a constant position relative to the base in the direction along the length of the string.
