Abstract: A stringed musical instrument may include various features, including any of a soundboard designed for efficient production of acoustic tone, a removable cover for easy access to the instrument's interior, a tailpiece mounted to receive and tension strings, one or more transducers to record and amplify musical tones, a dampening device that further improves operation of the transducers, a detachable thumbrest, an overbrace to strengthen supporting cross members that embody openings, and a rigid overlay that may be placed over an original fretted fingerboard to create a fretless surface for the strings to contact.

Abstract: A design for a transducer assembly which embodies two separate microphone elements attached to two separate goosenecks where both microphone/gooseneck assemblies are connected to a single service housing. The goosenecks are constructed in a unique method in order to provide a wide range of mounting positions while simultaneously protecting the microphone elements from distortion due to ambient mechanical energy. The designs include methods for mounting microphones and other transducers onto musical instrument or other fixtures using two part fastening systems, elastic cords, padded hooks, and other devices. An optional microphone cover is described which will serve to reduce or eliminate feedback and other unwanted sounds.

Abstract: A transducer system for an acoustic instrument such as a guitar or violin including a receptacle for mounting on the instrument coupled electronically to an output jack for mounting in a remote location on the instrument and a transducer or pickup assembly that plugs into the receptacle.

Abstract: A mount for positioning miniature (lavaliere) type microphones, transducers, or similar devices in musical instruments. Such microphones are attached to a flexible shaft which connects directly to an output jack in a manner that requires little or no modification of the instrument. Once installed, no parts of the mechanism are in a position which will interfere with playing the instrument. The flexible shaft permits the player to experiment with positioning the microphone in a variety of locations until the optimum location for sound reproduction is determined.
