A removable device for positioning a user's forearm and hand in relation to a guitar is provided. The removable device comprises: (i) a first strap overlying a first portion of the guitar and having attached thereto a first pad and a second pad; (ii) a second strap overlying a second portion of the guitar and joined to the first strap via a first connector, wherein the first connector is coupled to the guitar at a first point; and (iii) an adjustment mechanism overlying a third portion of the guitar and joined to the first strap, the second strap, the first connector, and a second connector, wherein the second connector is coupled to the guitar at a second point.

A utility article for protecting and covering the strings of a musical instrument, while providing options for visibility and display. The utility article, including a covering member made of flexible material and having a front side and a rear side. Four flaps extend from the left edge and the right edge of the covering member, wherein two flaps extend outwards to form a sleeve and the two flaps extend rearwards wrapping the neck of the musical instrument. The two pockets will serve for holding the user's common accessories and tools, while an attachable flap will allow the device to second as a guitar strap when not in its primary use.

The Spring Bracing System invention is disclosed for optimizing the musical voice of a stringed musical instrument by improving the transfer of musical string vibration energy and adding structural support and spring quality to targeted locations on the instrument's sound board. The Spring Bracing System, comprising a spring brace frame, a tensioning system, a fulcrum lever system, sound posts and sound braces, operates as a simple machine in transferring vibration energy generated when the instrument's strings are in motion. The adjustability of the system allows the musician to customize, optimize, and improve the musical voice of the instrument to his preference. On most steel string guitars, the Spring Bracing System can be installed without modification to the instrument. It can be installed in other types of stringed musical instruments, such as classical guitars, cellos and double basses, with minor modifications.

A foldable stringed instrument having a neck and/or body that may assume a reduced profile by folding an upper neck portion away from the playing position through the use of a translating bridge assembly and a translating truss assembly, wherein the foldable stringed instrument is capable of housing or otherwise being coupled to any of a variety of electronics or electrical components (e.g. a smart phone or tablet computer) having one or more applications (apps) for driving the operation, functionality and/or effects associated with the foldable stringed instrument.
