Abstract
Abstract This method and apparatus prevents improper string return by restraining an end portion of a string of a stringed instrument, such as a pedal steel guitar, free of longitudinal movement with changes in tension of the string from a predetermined level of string tension. The invention also involves applying tension force to the string operatively collinearly with a linear projection of an end portion of the string while maintaining an end portion of the string free of longitudinal movement with changes in string tension from a predetermined level of string tension.

Claim 1
Independent Claim
381 words
A method of avoiding significant improper string return by securing an end of a string to one end of a stringed instrument, the stringed instrument being of the type including tension changing means at the other end of the instrument operatively connected to the other end of the string for effecting selected and repeated increases and decreases in string tension from a predetermined normal string tension level during playing of the instrument, said inventive method comprising the steps of: selecting an end of the string opposite the end of the string connected to the tension changing means, said selected end of the string being essentially of uniform diameter therealong and free of any significant external protuberances extending therefrom; apportioning the selected end of the string into an outermost first portion and a next inwardly adjacent second portion, the first and second portions of the string and each having a selected elongated length; extending the first portion of the selected string end essentially linearly along its length; extending the second portion of the selected string end essentially linearly along its length; extending the first and second portions of the selected string end essentially colinearly along their lengths with respect to one another; applying restraining force on opposite transverse sides and over substantially only the total length of the linearly extending first portion of selected string end, the restraining force being applied to the string essentially only perpendicularly with respect to the colinear extension of the first and second portions, and the restraining force being of sufficient magnitude of restrain the first portion of the selected string end against longitudinal movement under application of the predetermined level of string tension and under the selective increases and decreases in string tension from the predetermined level; applying tension creating force in the string operatively at the first portion of the selected string end, the tension creating force being applied from the end of the stringed instrument at a point thereon operatively colinearly with a linear projection of the first and second portions of the selected string end, the tension creating force determining the predetermined level of string tension; repeatedly selectively changing the tension of the string from the predetermined level; and allowing the string tension to return to the predetermined level after each tension change.
