Self-compensating tunable bridge for string musical instrument

A tunable bridge for a string musical instrument, said tunable bridge comprising:

• a base plate securable to said string musical instrument;
• a rocker arm having a proximal portion, a distal portion and a rocker axis therebetween, said rocker arm being mounted for pivoting movement with respect to said base plate about said rocker axis between a lower position and an upper position, said rocker arm including one or more noise attenuation pads on said distal portion, said noise attenuation pads being configured to prevent direct contact between said rocker arm and said base plate when said rocker arm is in its lower position;
• a cam roller fork mounted for rotational movement with respect to said distal portion about a cam axis between a lock position and a release position;
• a cam roller mounted to said cam roller fork and configured to contact said base plate for translational movement relative thereto when said cam roller fork is moved between its lock and unlock positions, said cam roller being rotatably mounted to said cam roller fork for rotation about a roller axis such that said translational movement causes rolling contact between said cam roller and said base plate, said cam roller comprising one or more elastomeric rings disposed thereabout;
• an actuator arm actuatable about said cam axis between a first arm position and a second arm position,
• a multiplicity of string fingers, each said string finger having a tuning interface portion, a ball detent portion and a finger axis therebetween, each said ball detent portion being adapted to receive a string having a string ball, and to prevent said string ball from passing therethrough, each said string finger being mounted for pivotable movement with respect to said base plate about its finger axis between a first tuning position and a second tuning position, each of said string fingers including a foot on its ball detent portion, said foot being adapted to rest against said base plate when its respective said string finger is in its first tuning position, thereby restraining said string finger from pivotal movement past its first tuning position in a direction away from its second tuning position;
• and
• a plurality of tuning screws, each said tuning screw having an engagement tip and being threadedly disposed in said proximal portion for adjustable placement of said engagement tip at a respective axial distance therefrom, each of said engagement tips being configured to pressingly engage a respective said tuning interface portion.
