  • Publication number: 20180182361
    Abstract: Musical instruments have been covered in ornamentation since the beginning of time. Often, the designs shown on an instrument are an integral part of the performance. However, playing the instrument creates wear. Some wear on the instrument may he desirable, to authenticate that the instrument was used during a performance. However, wear on the back of the instrument may interfere with the functionality of the instrument. For example, wear on the front of a guitar from picking shows authenticity, but scratches on the hack of the guitar may interfere with the resonance chamber. This problem of balancing wear and preservation is a difficult balance to strike. What is needed is a protective attachment that preserves the functionality of the instrument, but allows it to age and demonstrate authenticity.

  • Publication number: 20170287455
    Abstract: An apparatus for covering a musical instrument such as a guitar. The system comprises a back section and a front section with each of the back and front sections being affixed along a lateral edge to a side section. The cover is formed with an interior area into which the musical instrument is inserted. The musical instrument is protected from damage in the event the instrument is mishandled, dropped or knocked into another object. Cut-outs in the sections provide access to the components of the instrument for a musician to access such components while playing the instrument with the cover system in place.
