A device that can be easily placed on and removed from an acoustic, stringed instrument, such as an acoustic guitar. When placed on a guitar, the device amplifies and clarifies the sound of the guitar, thereby allowing the guitarist to obtain quality sound and high volume. In addition, the device enables the guitarist control the timbre or sound characteristics of the guitar.

A method of assembling an anti-wolf resonator assembly for use with a string instrument is provided. The method includes positioning a first portion of the resonator assembly against a first side of a surface of the instrument, and magnetically coupling a second portion of the resonator assembly to a second side of the instrument surface that is opposite the first side of the surface. The surface is positioned between the first and second portions of the resonator assembly. The resonator assembly is configured to dampen at least one of a musical note and a vibration produced by the string instrument.

Stringed musical instruments, and methods for manufacturing such instruments, are provided that include a unitary shell that includes a head, a neck and a body, a separate sound board adapted to be attached to the unitary shell, wherein the soundboard extends from the head to the body, and a substantially hollow cavity extending through the head, the neck and the body. Exemplary processes include composite manufacturing processes and plastics manufacturing processes.

A travel banjo optimized for sound quality, portablity and ruggedness. The neck, fingerboard and string scale are identical to a regular banjo. The neck is attached to the body with a thumbscrew. The body consists of a front and back plate which are fastened together mechanically. A commercial drum head is tensioned by the force of the front and back plates being drawn together, applying pressure to the head and the tone ring. A string clamp is attached by a thumbscrew to retain the strings and bridge in when the neck is removed. The strings are attached to string posts at the end of the neck travelling over the bridge to a set of rollers, which redirect the string path to the rear where the tuning mechanisms are mounted in a protected area. The head and bridge are similar to a regular banjo to provide an authentic banjo sound.

A string instrument includes a body portion having a first longitudinal axis, an elongate neck portion having a second longitudinal axis and first and second opposing ends located along the second longitudinal axis, and a fastener that secures one of the first or second ends to the body portion, wherein the first and second axes are misaligned from each other in a same plane.

Devices, apparatus, and methods of using a replaceable nut with built on fret for a stringed instruments, such as for guitars and banjos. The novel combined zero glide nut with fret can be used as a zero glide nut system that can be substituted for the existing standard nuts on stringed instruments. The novel combined zero glide nut with fret eliminates the need for filing and adjusting the slots on the nuts, since strings do not harshly rub against inner sides and do not rub against the bottom of the slots in the nut. Compared to a conventional nut, the zero glide improves tuning stability, playability without string buzz on the fret, does not wear slots as occurs in a conventional nut and is more easily installed than a conventional nut.

A three-position mute for use with a musical stringed instrument, such mute having an elongated body with two pairs of legs extending therefrom, a slot defined between each pair of legs, a pair of notches defined in the bottom of the elongated body, such notches for engagement with selected strings of the musical instrument in selected modes of use and the slots for engagement on the musical instrument's bridge in a selected mode of use, such modes of use including a bridge engagement position in a first mode of use, a bridge-contacting position in a second mode of use, and a resting position with the mute installed on the strings between the bridge and the tailpiece.

A stringed instrument, such as a guitar, having components made from glass, and methods of manufacturing and assembling the same are provided. In one exemplary embodiment, the present invention provides for manufacturing a glass fretboard, manufacturing glass frets, assembling the glass frets to the fretboard, and assembling the fretboard to the neck of the stringed instrument. In addition to the fretboard and frets, other components of the stringed instrument may also be made from glass. For example, the present invention further provides a method for manufacturing glass saddles and top nuts to allow the strings of the stringed instrument to substantially entirely contact glass. This produces a clean, crisp sound and overcomes the problem of generating an inferior sound that results from the imperfections found in natural wood components, for example.

A banjo tensioner is provided in which wave springs inserted between the flange and the nuts operate to maintain a constant tension on the banjo hooks. The invention also contemplates using a wave spring as placed between the washer that applies pressure to the rim and the top coordinator rod nut to maintain the pressure on the inside of the rim. The tensioner may also be used on a drum.

A tuning machine for a stringed instrument comprising: an input shaft having a first end, and an opposite second end having an eccentric, the input shaft being rotatable in response to an input from a user; a gear member or rotor with a central axial bore to receive the eccentric to move the rotor though a circular motion as the input shaft rotates, the rotor having a first or upper gear portion with external first lobes, and a second or lower gear portion with external second lobes; a first or upper ring gear having internal first teeth positioned around the first lobes of the first gear portion; a second or lower ring gear separate from the upper ring gear and having internal second teeth positioned around the second lobes, said upper and lower ring gears being larger than the rotor to accommodate the circular motion of the rotor within said ring gears such that at least one of the first lobes meshes with at least one of the internal first teeth, and at least one of the second lobes meshes with and drives at least one of the internal second teeth of the lower ring gear as the rotor moves through its circular motion to rotate the lower ring gear about its central axis; and a string post driven by the lower ring gear to wind a string of the instrument as a result of rotation of the input shaft in one direction and unwind the string as a result of rotation of the input shaft in an opposite direction.
