Description

DESCRIPTION OF THE DRAWINGS

(1) In the drawings:

(2) FIG. 1 is a plan view of an electric guitar embodying the present inventions.

(3) FIG. 2 is a side view of the tremolo showing the Magnetic Stabilizer mechanism positioned within the spring block descending from the base plate. Two magnets in close proximity, poles variably arranged to provide a force of repulsion, comprising a variable pre-load exerted through the contact pin against the tremolo pocket face operable at initial contact to enforce initial position. The Magnetic Stabilizer pre-load complements the biasing element to create a variable “soft” stop stabilizer. Threading the adjustment element in this setup is operable to variably adjust the proximity of the two opposing magnets on axis to adjust the rate of the force of the pre-load in the context of the configuration's interdependence with elastic force of the biasing element at initial position.

(4) Also shown is a dual loading/locking macro-tuner mechanism comprising an articulated extended tip of extended laver-clamp improvement to facilitate threading a string through the nose slot to pivot or lift the clamp lever for successful loading of the string from a direction opposite or distinct from the traditional direction of operation carried out from the direction the tailpiece portion securing the string to the instrument.

(5) FIG. 3 is a side view of the tremolo showing a simple Magnetic Stabilizer embodiment. A first magnetic element is installed in the face of the tremolo pocket wherein a magnetic adjustment member, comprising a second magnetic element, threadedly connected to the base element, is in variable proximity to the first magnetic element in tremolo pocket, operable to exert a variable limited force operable at initial contact to enforce initial position. The second force of tension created by the opposing magnets repelling each other complements the first force of tension comprising the biasing element to create a variable “soft” stop or stabilizer. Threading the adjustment element or thumbwheel in this setup is operable to variably adjust the rate of the force of the pre-load in the context of the configuration's interdependence with force of the biasing element at initial position.

(6) FIG. 4 shows a fully independent adjustable Magnetic Stabilizer, repurposing the Global Tuner thumbwheel arrangement with the extended portion to variably support and position a dual Magnetic Stabilizers that include a guide element, a fine adjustment element or extension element, a pre-loaded magnetic arrangement, the magnetic tensioner element is threadedly connected to the extended portion, positioned additionally within cooperating cavities in the main spring block. The tensioner element formed to receive a first magnetic element and guide element, a second spring positioned between the guide element and the first magnetic element, threading the tensioner element adjusts the force of tension created by the repulsion energy, twin mechanisms are used, one on each side of the center mounted thumbwheel adjustment element operable to variably enforce initial position. The fine adjustment element is theadedly secured within the guide element and operable to adjust the tip in dimensions up to more than 0.250 from the spring block to the first face for initial contact. Since threading the tensioner element is independently operable to variably adjust the rate of the force of the pre-load, this configuration benefits from the increased stability and improved acoustic coupling and frees the thumbwheel element to global tune the stabilized initial position over time. The dual Stabilizers are collectively capable of exerting a combined force of at least 8 to 10 pounds to variably ensure initial position

DETAILED DESCRIPTION OF THE INVENTION

(15) In FIG. 1, an electric guitar 1 is illustrated comprising Headpiece Tuner 2 at one end, a body 3 at the other end, with neck 4 extending between head 2 and body 3. Six of each string 6 extends from Headpiece Tuner 2 to body 3 over neck 4. Neck 4 forms fret board or fingerboard 5 for guitar 1. At Headpiece Tuner 2, each string 6 extends over nut 7 forming first critical point 8 for each string 6 and is secured. Nut 7 is located at the transition of neck 4 to head 2. Headpiece Tuner 2 includes Truss Rod Thumbwheel 9. On body 3, strings 6 are secured to fulcrum tremolo 10. Fulcrum tremolo 10 has arm 11 for pivoting tremolo 10 to provide the vibrato effect on the strings. Fulcrum tremolo 10 has six intonation modules 12, one for each string 6. By manipulating tremolo arm 11, the entire fulcrum tremolo 10, not including the riser posts and inserts (and in varied designs, related bearing assembly elements), can be pivoted to achieve the desired tremolo effect.
