Abstract
In a construction of a transducer or pickup unit for musical instruments having strings, a piezo-electric element is fully embedded within a synthetic resin shield block having top crest for supporting strings while projecting electrode terminals outside of the shield block for direct connection to a printed electric circuit, thereby avoiding drawbacks caused by use of electric lead wires in the conventional pickup unit and damage by atmospheric moisture. The pickup assembly has unitary means for collectively carrying the pickup units at precisely uniform intervals, thereby simplifying registration of the pickup units at correct positions relative to the strings and printed electric circuits.
