Abstract
A bridge pickup for a string instrument includes a sensor assembly mounted in a U-shaped base. The sensor assembly includes a cast member encapsulating a holding means which holds an array of piezo sensor elements. The cast member extends below the sensor elements and includes an upper crest portion for supporting the strings of the instrument. A groove formed in the cast member at a point below the sensor elements extends to the lower electrode contact faces of the sensor elements, and a conductor placed in the groove provides an output. A U-shaped channel holds the sensor assembly and the conductor. Preferred conductive and casting materials are shown, and a method of manufacture is described.
