Disclosed is an improved vibrato device. The typical components of the disclosed device include, but are not limited to, a dual spring-loaded lever arm 10. The lever arm 10 is intended to sit separate and away from the instrument's strings 70 to allow for the user to manipulate the instrument's vibrato while playing by manually moving the lever arm 10 closer to or farther from the instrument. The lever arm 10 connects to the dual spring system 15; the dual spring system 15 houses the vibrato device's springs that allow vibrato manipulation and sits attached to the tremolo system's tailpiece 60, which anchors the vibrato device to the instrument, and the pivoting metal bar 40. The pivoting metal bar 40 is the strings' 70 anchor-point at the base of the instrument, and the bar 40 pivots in response to the lever arm 10 being raised or lowered. When the bar 40 pivots, it either lessens the strings' 70 tension when the lever arm 10 is lowered or increases the strings' 70 tension when the lever arm 10 is raised.

HEADPIECE TUNER is integrated into the nut arrangement of a traditional headless musical instrument featuring lever-based individual string clamps, a removable nut, a truss rod adjustment feature and multi-function cross bar handle. A Magnetic Tuner comprising at least one of two magnetic elements secured to a tremolo, in fulcrum tremolos, moveable therewith about the tremolo pivot axis, in a mechanism operable to provide a first force of tension comprising the traditional tremolo coil spring biasing element and/or, in the case of coil spring integrated tremolo stabilizers, provide a second force of tension to enforce the tremolo at the equilibrium point or initial position.

A tremolo device for static retention of a plurality of musical instrument strings in a stringed instrument. The tremolo device has a body with an upper surface, a neck portion, and a plurality of strings anchored at a first end of the neck and extending over at least a portion and secured to the tremolo device at the other end of the neck portion and the body and possesses an inertia block mechanism with substantially solid construction disposed to receive and securely retain a plurality of raw instrument strings without removal of a ball end from each string. The inertia block has an upper portion, a lower portion, and a plurality of internal, longitudinally displaced, cylindrically shaped, string retaining chambers designed to pass through an entirety of the block mechanism. The string retaining chambers have an upper and lower portion corresponding with the upper and lower portions of the block.

Sonic improvement for all stringed instruments that employ a fulcrum tremolo bridge system with back of instrument counter tensioning springs. The improvement is provided by securing springs to claw assembly, as well as securing claw assemble to a flat plate of material which is in turn secured to instrument body. The claw and resonator plate can be fabricated as two individual pieces then fastened together or as a combined one piece assemble that is then fastened to instrument body.

A tremolo bridge mechanism enables pitch adjustment of strings with both ends of the string rigidly attached to the stringed instrument. A pitch adjustment feature incorporates a deflection arm that is coupled with an actuating rod that pivots about a rotational axis as controlled by the tremolo lever. The pitch adjustment features can be configured to enable normal tremolo pitch adjustment or an opposite pitch change for a given motion of the tremolo lever. In a first embodiment, linkages between the actuating rod and deflection arm can be modified to provide variation in the pitch affect. In another embodiment, a spring array can be oriented in two different directions to provide variation in pitch effect for each individual string. In addition, a pitch adjustment feature may be removed, or a string can be routed around the deflection arm, to prevent pitch change with tremolo lever action.

The Drop Tuner comprising a pivoting lever element and two ring-like elements in an arrangement operable to quickly alter the position of a macro-tuner or other string tuning element on the instrument body to change the tension of a musical instrument string from one pre-selected pitch to another and back by moving the lever to one of two corresponding adjustable pre-selected positions. “Drop Tuner” refers to an adjustment device added to a string tuner element, macro-tuner or similar, with the capacity to quickly change from one adjustable predetermined pitch to another adjustable predetermined pitch and back comprising at least two adjustable predetermined tensioning positions.

A tremolo and tuning apparatus is provided for a stringed musical instrument having a body, a neck extending from the body, a nut on an end of the neck remote from the body, and a string extending over the neck. The string makes a first critical contact at a point on the nut of the instrument and a second critical contact at a point on the apparatus. The apparatus includes a mounting frame configured for mounting on the surface of the body, an attachment post secured to the body, a base plate pivotally mounted with respect to the attachment post and having a surface adapted to receive a force, a string mounting assembly mounted on the base plate for holding the string, and a resilient member assembly for engagement with the mounting frame outside the body of the instrument and supplying a force to the base plate surface.

The invention relates to an attachment arrangement for the strings of a stringed instrument, especially a guitar. To the body of the stringed instrument is attached a bridge body, first restraining means for restraining the strings from the first end area, second restraining means, which are arranged in conjunction with the bridge body for restraining the strings from the second end area. Lever means are arranged in conjunction with the bridge body in order to move the second restraining means for temporarily loosening and/or tightening the strings by means of a lever part included in the lever means. The lever means are provided with moving means comprising at least one moving mechanism, which is a mechanism separate from the lever means. One or more second restraining means are arranged to move with respect to the bridge body. The moving means are arranged to transmit the movement of the lever means into the desired movement of one or more restraining means.

Disclosed is a torsion based tremolo apparatus that includes a moving plate rotatably coupled to a mounting plate. A torsion device imparts torsional force to the moving plate relative to the mounting plate around an axis of rotation. The mounting plate is used to attach the tremolo apparatus to a guitar or other string musical instrument. Adjustable bridge clamps and tuning plates coupled to the moving plate may be used to set the tension on the instrument strings as desired. Rotation of the moving plate relative to the mounting plate alters the tension on the instrument strings.
