Claim Text:
1. An improvement for mounting electric vibration sensors in conventional stringed instrument at any point on said instrument, comprising: a. sensors for transforming the vibrations of body parts and strings of said stringed instrument into electric signals of an audio nature, b. a plurality of paired and marked mounting points for said sensors in or on said face of said instrument, placed on opposite sides of said strings in the area between the neck and tailpiece of said instrument, near line positions perpendicular to said strings, said line positions placed near mathematical projections of the fret scale of said neck, called here virtual fret marks, visibly marked on the body of said instrument beside said mounting points, c. a mounting and adjustment system, capable of placing said sensors in a plurality of positions and orientations in a cavity or a face of said stringed instrument, allowing for at least five degrees of freedom, based upon mounting plates containing a hole and a slot, said hole used to mount one end of said sensor via a spring and screw, with said mounting plate shaped such that said mounting plate can rotate about said sensor mounting screw at least 180 degrees relative to said sensor without interfering with the body of said sensor, said slot affixed either of said paired mounting points, with another of said mounting plates at the other end of said sensor, such that said sensor with a pair of mounting plates can rotate about and slide to and from said mounting points, and adjust in distance from said strings, whereby each of said ends of each said sensor can be moved independently toward and away from said strings, giving two degrees of freedom, and whereby each said end of said sensor can move independently along the direction of said strings, to positions between said neck and said tailpiece, giving two more degrees of freedom, and whereby each said sensor can move across the direction of said strings, perpendicular to a line between said neck and said tailpiece, giving one more degree of freedom, thereby allowing the player to choose and change the number, kinds and orientations of said sensors mounted upon said instrument.
