Abstract
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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
155 words
A combination of a guitar and a tremolo and tuning apparatus, wherein each string makes a first critical contact with the guitar at a point on the nut of the guitar and a second critical contact at a point on the bridge of the guitar, the combination comprising: a guitar comprising a guitar body portion and a guitar neck portion, the guitar body portion having a bridge thereon; means for moving the second critical contact point of each string individually so as to change the distance between the first and second critical contact points of said each string, thereby changing the harmonic tuning thereof; tremolo means for simultaneously changing the pitch of all of the strings of the guitar; and means mounted on said tremolo means, and hence movable therewith, for fine tuning each string individually by changing the tension thereof, essentially without changing the distance between the first and second critical contact points thereof.
Claim 2
Dependent Claim
155 words
A combination of a guitar and a tremolo and tuning apparatus, wherein each string makes a first critical contact with the guitar at a point on the nut of the guitar and a second critical contact at a point on the bridge of the guitar, the combination comprising: a guitar comprising a guitar body portion and a guitar neck portion, the guitar body portion having a bridge thereon; means for moving the second critical contact point of each string individually so as to change the distance between the first and second critical contact points of said each string, thereby changing the harmonic tuning thereof; tremolo means for simultaneously changing the pitch of all of the strings of the guitar; and means mounted on said tremolo means, and hence movable therewith, for fine tuning each string individually by changing the tension thereof, essentially without changing the distance between the first and second critical contact points thereof.
Claim 3
Dependent Claim
22 words
An apparatus of claim 1, including a means in the vicinity of the nut for securely holding the strings of the guitar.
Claim 4
Dependent Claim
200 words
The combination of a guitar and an apparatus for tuning a guitar, wherein each string makes a first critical contact with the guitar at a point on the nut of the guitar and a second critical contact at a point on the bridge of the guitar, the combination comprising: a guitar comprising a guitar body portion and a guitar neck portion, the guitar body portion having a bridge thereon; string support means for each string of the guitar, said string support means including thereon the second critical contact point for each string; means in the vicinity of said string support means for securely holding each string; means for moving said string support means so as to change the distance between the first and second critical contact point of said strings, thereby changing the harmonic tuning thereof; and means for moving said string holding means and also said string support means in such a manner as to change the tension in the string so as to fine tune the strings individually but not change the harmonic tuning thereof, while the string is securely held and essentially without changing the distance between the first and second critical contact points of the string.
Claim 5
Dependent Claim
200 words
The combination of a guitar and an apparatus for tuning a guitar, wherein each string makes a first critical contact with the guitar at a point on the nut of the guitar and a second critical contact at a point on the bridge of the guitar, the combination comprising: a guitar comprising a guitar body portion and a guitar neck portion, the guitar body portion having a bridge thereon; string support means for each string of the guitar, said string support means including thereon the second critical contact point for each string; means in the vicinity of said string support means for securely holding each string; means for moving said string support means so as to change the distance between the first and second critical contact point of said strings, thereby changing the harmonic tuning thereof; and means for moving said string holding means and also said string support means in such a manner as to change the tension in the string so as to fine tune the strings individually but not change the harmonic tuning thereof, while the string is securely held and essentially without changing the distance between the first and second critical contact points of the string.
