  • Patent number: 5955689
    Abstract: A fully adjustable acoustic guitar bridge is claimed that allows the strings (e.g. nylon or steel) of an acoustic guitar to be separately and continuously intonated, accurately and easily, whenever necessary. The bridge system employs a minimum of alterations to the traditional non-adjustable acoustic guitar bridge to retain the acoustic qualities of the instrument. In one embodiment, recessed rear-loaded cap screws utilize the forward and downward pull of the strings to stabilize the adjustable saddles; in another, recessed, front-loaded cap screws utilize a c-clip to stabilize the saddles. A threaded saddle capture on each saddle provides stability, continuous threading capability, and the freedom to use acoustically resonant materials (e.g. bone, phenolic, composites, etc.) for saddles. In one embodiment, the string's downward pressure transmits string vibration to the soundboard; in another, a set-screw assists this transference of sound.

  • Patent number: 5728956

The bridge system employs a minimum of alterations to the traditional non-adjustable acoustic guitar bridge to retain the acoustic qualities of the instrument. Recessed, rear-loaded cap screws utilize the forward pull of the guitar strings to stabilize the adjustable saddles. A threaded saddle capture on each saddle provides stability, continuous threading capability, and the freedom to use acoustically resonant materials (bone, phenolic, composites, etc.) for saddles. These features eliminate the need for springs or other fasteners, which would have a negative effect on the acoustic guitar's tone and sustain. A rosewood shim is employed on acoustic/electric guitars over the internal bridge pickup.
