Apparatus, such as a stringed musical instrument, is provided with intonation modules that include a novel fine-tuning invention that eliminates modifying strings required of prior art comprising an improved clamping element, a hollow tube element forming a tailpiece at one end furthest the second critical point and a novel adaptor plate element connected to a base plate. Clamping the sting renders the string substantially inextensible between the clamping point and the tailpiece formed at the end of the hollow. Threading the string through the hollow tube portion delivers the string over the second critical point effortlessly. The hollow portion of the string holder element is threadedly engaged with an adjustment knob and makes bearing contact with adaptor plate for fine-tuning. The adaptor plate can be added to a unitary component forming the base plate and can provide other functions. Reverse threaded screws intonation module attachment screws are provided to complete a comprehensive base plate / intonation module format that integrates to a common standard all elements of the two otherwise disparate two primary vintage fulcrum tremolo designs except for riser post spacing. An improved ball bearing arrangement is also disclosed.

A swingable tremolo for a string instrument. A tremolo block connected with the tremolo body is in turn connected through a link with a sliding block on the bottom of the instrument. A first spring urges the sliding block against the tensile force of the strings. A movable stopper is engageable by the sliding block as it moves rearward. A second spring also urges the movable stopper forward. The tensile force of the instrument strings is greater than the opposite force of first spring but less than the sum of the spring forces of the first and second springs, whereby the tremolo body may be tilted up or forwardly to reduce string tension or tilted down or rearwardly to increase string tension, and upon release of the tremolo body, the forces of the springs acting on the sliding block and the movable stopper act against the tensile force of the strings to bring the tremolo body into an equilibrium state.

A quick-release tremolo lock device for installation into a tremolo or vibrato assembly recess or cavity, and for mounting to a movable bridge or a tremolo or vibrato block of a stringed instrument such as a guitar. The tremolo lock device includes a spring mount that is adapted to be fixedly attached to at least one wall of the tremolo or vibrato cavity to prevent relative motion between the spring mount and the cavity. The spring mount is also configured to capture an end of at least one tremolo or vibrato return spring. A slide key is also incorporated into the quick-release lock device, which is connected to the spring mount about a proximate portion of the slide key. The releasable tremolo lock device is also adapted with an adjustable quick release slide receiver that is adapted to receive and to releasably capture a distal portion of the slide key to, when engaged, capture and fix the position of the receiver relative to the slide key. A tail piece member is also part of the lock device and is joined to the quick release slide receiver. The tail piece is further configured to be mounted in the tremolo recess to the tremolo block of the guitar. In any of the embodiments of the invention, the lock device may also incorporate various types of joints that are adapted for movement in multiple degrees of freedom to compensate for natural and induced misalignment between the tremolo block, the recess wall, and the tremolo lock device.

A tremolo assembly is implemented for modulating the string tension on a guitar by mounting a bridge carrier on a sliding mount with the fore and aft displacement thereof effected by a transverse cam implemented fulcrum piece opposing the string tension. The sliding mount limits the bridge translation to the string plane, thus resolving all bending and lateral string forced. A forwardly and rearwardly aligned set of manual levers is then useful in modulating downward and upward the tension of the strings in unison against a set of bias springs.

A guitar has a wrench tremolo bar thereon, replacing the standard tremolo bar, with the wrench tremolo bar having a desired wrench on at least one end of the wrench tremolo bar, to cooperate with the string fasteners on the guitar, which greatly facilitates tuning, changing or replacing of a guitar string.

A stabilizer for a tremolo bridge prevents disablement of an instrument in the event of string failure. A cam, operated by the player, serves to support a tremolo bridge such that pre-failure tuning of the remaining strings is restored. A method is disclosed for stabilizing a tremolo bridge, comprising steps of ascertaining the normal position of the bridge with strings intact and the tremolo not actuated, providing a retractable stabilizer capable of maintaining the bridge in that position, and selectively using the stabilizer to oppose disabling movement of the tremolo bridge in the event of a string failure, or for purposes of facilitating tuning of the instrument. Novel designs of the components of the stabilizer are also disclosed.
