Abstract

The present invention is applicable to stringed musical instrument having movable bridge, and comprises novel means for achieving intonation selectivity string for string in the tuning of an instrument and to ensure the consistent turning thereof during operation. Essentially the system is a method and apparatus for correcting the tuning of fretted and nonfretted instruments by offsetting longitudinally individual contact '"'"''"'"''"'"''"'"'nut'"'"''"'"''"'"''"'"' and bridge supports for preselected strings a variable distance from the 12th fret or center of scale length.

Claims

1. In a stringed musical instrument comprising, a finger board of fixed scale length, and body in extension thereof, frets fixedly positioned on said finger board, strings overlying said finger board, and at least a portion of said body, a nut adjustable longitudinally on said finger board about the conventional location of a nut on said finger board, said nut including displacing means for each string for tuning each said string individually, and a bridge mounted upon the body and adjustable longitudinally relative to the conventional location of a bridge on said body, said bridge including adjusting means for each string for tuning each string individually.

2. The improvement of claim 1 in which the respective displacing means are slidably retained for longitudinal adjustment relative to the centerline, each said displacing means having a channel slide disposed longitudinally of the instrument.

3. The improvement of claim 2 in which the respective displacing means slidably envelope the strings at point of contact.

4. The improvement in stringed instruments according to claim 1 wherein each said nut displacing means comprises:

a nut assembly located at the upper end of the scale said assembly including;

individual string roller supports and corresponding guides therefor, each said support and guide being adjustably fixed to the neck of the instrument and means to vary the vertical disposition of each said roller and guide.

5. The improvement in stringed instruments according to claim 1 wherein each said nut displacing means comprises:

a nut assembly located at the upper end of the scale, said assembly including individual string roller supports and guides connected to said supports, anchor means securing each support and guide in adjustable sliding relation to the anchor means.
