Abstract
The fine tuning apparatus functions as the bridge element (20) of a stringed instrument. The fine tuning apparatus includes a base element (22) and a series of fine tuning elements (40), one for each string. Each fine tuning element (40) includes a forward block element (42) and a rear block element (52) which is rotatable relative to the forward block element. A string of the musical instrument makes critical contact with the fine tuning apparatus at point (59) on the rear block element (52) and maintains surface contact with the rear block element (52) as the surface slopes downwardly and rearwardly from the bridge critical contact point (59), until the point where the string is clamped against surface (60). Means (64, 70) are provided for adjusting the rotatable position of the rear block element (52) relative to the forward block element (42), which results in a change in the tension of the string and hence the fine tune of the string.
