Abstract: Disclosed is a fingerboard protector for stringed musical instruments which demonstrates a novel solution to the problem of fingerboard wear caused by the players fingers making contact with the fingerboard. This physical contact in addition to the natural acidity of the players fingers can wear down the fingerboard creating indentations as well as contaminating the fingerboard with tarnish and grime. In the case of a fretless instrument, the strings are pushed directly into the fingerboard causing wear to occur at a much faster rate. My present invention sets out to solve this problem by creating a fingerboard protector safeguarding it from undesirable wear during normal playing of the instrument. The ease of installation and removal will appeal to musicians who want to protect their instrument as well as give it a new and unique look.
