Abstract
An arched top bridge upper section including a wood top section slotted to accept a string saddle that may be plastic, bone or similar material. The wood section is laminated or affixed to a lower metal section. A slot completely through the wood section exposes a top flat surface of the metal section. A piezo pickup element installed in the slot below a solid or segmented string saddle element is pressed uniformly against the metal section by string pressure on the string saddle to ensure even response on all strings. Transfer of string energy is more efficient than standard all-wood construction, resulting in greater sustain of plucked notes and a broader frequency response. An arch top guitar utilizing this bridge construction has more similar tonal and sustain characteristics to a typical flattop acoustic guitar while consistent contact with the piezo element results in even string-to-string output and response.
