An adjusting member is pivoted on a sound post to adjust a length of the sound post from the outside of the sound box of a musical instrument. The adjusting member comprises a main body and at least one adjusting arm arranged on the main body. Through the sound post provided with the adjusting member, a user can easily adjust the tightness of the sound post against the upper and lower plates of the sound box through a hole of the sound box, such as F sound hole, connected with the outside to achieve the effect of adjusting timbre of the musical instrument.

A dampener for a banjo that attenuates unwanted overtones/reverberation while preserving the all-important fundamental sound with minimal reduction in bass, treble and volume. The dampener has a cylindrical outer shell having a diameter of about two inches and a length corresponding to the inner arc of the banjo. The cylindrical outer shell is formed from a cotton poplin fabric, and the filling comprises polyester fibers.

A mute for a stringed instrument has a formed bar of metal, plastic or other suitable material, the ends of which are folded to allow the part to wrap around the outermost strings, for example, the high E and low E strings of a 6-stringed guitar, in such a way as to be held firmly in place by the tension of the strings, but allowing for quick installation and removal. The inner surface of the mute is lined with a suitable material such as rubber or felt that makes firm contact with each of the strings between the bridge saddle and the tailpiece, effectively stopping the strings between the bridge saddle and tailpiece from producing an audible sound or resonance. The mute eliminates or mitigates vibration of that portion of the strings that might otherwise be undesirably picked up, especially by a bridge pickup of a hybrid guitar.

An accessory for changing the timbre of a stringed instrument is provided, comprising a body having a vertical opening and a horizontal slot formed in the bottom surface from one edge into the vertical opening; an adjustment rod within the horizontal slot; and a dampener within the vertical opening associated with at least one string of the stringed instrument to which the accessory is attached. The adjustment rod has an upwardly angled inner end within the vertical opening in the body. The dampener comprises a dampener body; a soft fabric covering a top surface; and a bottom surface having a horizontal groove with a downwardly angled top surface matching the angle of the angle of the adjustment rod. Moving the adjustment rod inwardly moves the dampener upward and applies pressure to the string; moving the adjustment rod outwardly moves the dampener downward and reduces the pressure on the string.

A mute is positioned beneath the strings of a stringed instrument and adjusted to make contact with one or more of the instruments strings. In this manner, the mute may be used to selectively dampen or restrict the normal vibration of the strings and, consequently, the sound made by the strings. The end result is that the natural vibratory sounds associated with stringed instruments may be altered, using the mute to remove some or all of the natural frequencies, subharmonics, loudness and sustain associated with the vibration of the strings, essentially deadening the natural sound of the instrument. Additionally, in at least some preferred embodiments of the present invention, additional devices may be used to create and introduce new and enhanced sounds from the vibrations of the strings.

This banjo mute uses a unique design to expand and contract in order to fit between the coordinator rod or dowel stick of most banjos, and the underside of the banjo's head. It acts by applying varied pressure at different points along the underside of the banjo's head, thus effecting the volume, tone, and resonance of the instrument. It provides customizable volume adjustment and tonal control based on proximity to the bridge and amount of pressure applied. It could be used in a similar manner to effect the volume and tone of other stringed instruments.
