Abstract: A counter-force mechanism is provided for use with a stringed instrument, such as a pedal guitar, which neutralizes the adverse effects on adjoining strings during the sharpening or flattening of notes. In one embodiment the counter-force mechanism is affixed to the tone changer axle near the pickup and in another embodiment the counter-force mechanism is affixed at the opposite end to the head of the guitar in contact with the strings. Pull and push rods connected to the foot pedals and knee levers operate the counter-force mechanism automatically as the pedals and levers are used, as is standard while playing.

Abstract: The invention as described herein consists of a string mounting apparatus as may be used with stringed musical instruments to improve the quality of the sounds emanating therefrom and to provide high quality reproductions of sounds as the musical instrument is played.

Abstract: This invention consists of a novel string assembly for split tuning a steel guitar or other musical instrument having pedals or levers for varying the pitch of the sounds produced by the strings as they are plucked. The mechanism of this invention allows the musician to play a particular string and produce a musical tone absent any pedal movement, the same string played with a first pedal depressed produces a second tone and with only a second pedal depressed produces a third tone. A fourth tone is then capable of being produced by the string after split tuning when both pedals are simultaneously depressed.
