ABSTRACT:
Means for tensioning the strings of a guitar includes a rotary adjusting member, a manually operable control member, and a worm gear type drive means connecting the control member to drive the adjusting member. The adjusting member includes a portion for holding the tail end of a string that is supported on a string tensioning portion of the adjusting member. The string tensioning portion includes a convex surface that is eccentric with respect to the axis about which the adjusting member rotates and is constructed so that there is a non-linear relationship between incremental movements of the adjusting member and tensioning of the string, with this relationship being such that the rate of string tensioning decreases as the magnitude of string tension increases.
