    is my patent for a new and improved body and bridge bracing system for stringed musical instruments.
    Patent US8138403 -  Brace for Stringed Instrument.  Can be found at Google Patents Search.  Basically if you drop this number (Patent US8138403) into your Google search box, the original patent will be displayed as it is listed in the US Patent Office Database.
    It includes a bracing system that consists of an upper brace located in the upper body of the instrument's body and a lower brace located in the lower body. Two or more longitudinal braces connect to each of the lateral braces and provide the instrument's neck, body, and soundboard support against the constant stress of the strings. A bridge reinforcing means is also included and consists of two or more truss rods. The rods connect the upper body lateral brace to the bridge area and further counteract the tension of the strings thereby preventing damage to the bridge and soundboard.
    The soundboard of an acoustical stringed instrument has to do three things, structurally support the neck and neck block area, anchor the bridge and strings and produce the sound. Soundboard design and bracing has always been a give and take, build the soundboard to light and the instrument sounds great but in a short period of time the neck will fold up thus racing the string height and rendering the instrument unplayable; build the soundboard to heavy and the instrument will be very durable but will not produce the desired sound. By eliminating the need to support the neck area, this bracing system reduces the stresses that are imposed on the soundboard from the neck. By bracing the neck block area and transitioning the structural demands of the neck toward the lower bout it frees up the design of the soundboard to more creative ideas.
    There are two separate systems in this patent, (1) The truss rod system that anchors the bridge and (2) The structural bracing that reinforces the the body and the neck area. There is some debate as to whether or not the truss rod system for the bridge actually enhances the sound but all parties involved are of the agreement that a guitar/musical instrument produced with this design does sound as good as any other design that is commercially available. However,
    all parties involved are of the firm agreement that
    when an instrument is built using just the bracing system that reinforces the the body and the neck area, along with conventional X or fan bracing for the soundboard, it frees up the the structural constraints imposed
    upon the soundboard allowing for more creative design of the soundboard.
    My partner and I have built several guitars using this method with great success.

    Even Though I have listed it as a buy it now offer I will consider any and all offers such as selling the patent outright, on a royalty basis or licensing the patent. Lets be creative!
