Abstract: The invention provides elements used to attach a standard magnetic pickup, in conjunction with a feedback reduction device, into the sound hole of an acoustic guitar in a manner that does not alter the inherent sound characteristics of the underlying guitar. The approach put forward provides a significant advantage by providing the ability to install a broad range of commercially available standard magnetic pickups, which combined with the feedback reduction device, provides the capability to achieve high gain amplification utilizing an open body acoustic guitar while eliminating the highly objectionable squeal that is customary in this type of application. The invention consists of a basic modification kit: the pickup mounting elements, the pickup itself, the feedback reduction device, the metalized guitar strings, the conductive string anchor bracket, and the interconnect cable assembly.

Abstract: The interface device provides a means to install a standard magnetic pickup into the sound hole of an acoustic guitar in a manner which employs the use of a commercially available feedback reduction device. The interface mounting device provides the ability to use standard magnetic guitar pickups with an acoustic guitar that would normally require a special purpose guitar pickup. Further this interface mounting device provides a means to install the standard magnetic guitar pickup in a manner that is both secure during its operation, is adjustable to fit personal taste, is totally removable, and does not permanently affect the underlying acoustic guitar.
