Abstract
A device for setting the tension in a string of a stringed musical instrument whereby a musician can instantly retune the string to play either one of two predetermined notes by merely actuating a lever. The device is preferably attached between the tailpiece or body of the instrument and an end of the string. The element of the tuner to which the string is attached (a string anchor) moves with a rectilinear motion to change the string tension. Two embodiments are disclosed, one of which used a rotating cam to position the string anchor, and the other of which uses a two-bar linkage to position the string anchor.
