ABSTRACT:
An improved pickup system for stringed musical instruments, adaptable to all types of stringed instruments, in which strings pass through the hollow central portion of coils and the magnetic field within coil windings is perpendicular to the windings and parallel to the string axes. The described embodiments include an individual coil encompassing each string and a magnetic field reversed in polarity in portions of a coil oppositely disposed to a string. Magnetic elements provide an enclosed magnetic field limiting pickup response to a short, defined segment of string near an instrument's bridge. Described acoustic pickup embodiments are mounted directly to the bridge and interrupt the circle of acoustic feedback. Violin family pickup embodiments provide preferential sensing of string motions parallel to the string plane and adjustability of string response. The pickup system is designed to provide efficient and precise translation of string harmonic motions and thus reproduce the overall tonal characteristics of a stringed musical instrument.
