  • Patent number: 5455381
    Abstract: An intonation adjustment system is provided for a stringed instrument. A saddle setup tool has a plurality of selectable, distinctly spaced intonation points so that a preferred one of the selectable, distinctly spaced intonation points can be determined for each string of the instrument. Then a bridge saddle is constructed from a set of prefabricated candidate saddle segments by selecting a group of selected saddle segments making up the instrument saddle and providing the desired combination of intonation points as determined with the saddle setup tool. A pickup for an amplified instrument provides adjustable positioning of individual piezo-electric transducer elements so that relative volume outputs of the strings may also be adjusted.
