Abstract: A sound manipulator comprising a touch sensitive sensor detecting finger tapings and multiplying them electronically on simultaneously produced sound, such that touches and releases affect sound composition in part (e.g. added sound effects and their characteristics) or as a whole (e.g. full or partial muting). The Sound manipulator may be attached to a guitar and allow the player both pick and tap fretted tones to give a fully new type of sound producing to the guitar. Rhythmical and electronic music may be imitated by the Sound manipulator, without losing the basic authentic guitar sound and while maintaining the flavor of live play.

Abstract: The proposed invention is a portable multi-sound effect system providing a novel and unique solution for processing the electrical audio signals created by a guitar. The innovation according to the present invention is by attaching a signal processing unit along with a touch-sensitive dynamic control unit upon the front panel of the guitar's body for controlling and processing electrical signals produced by an amplified guitar, e.g. electric, bass, acoustic or classic guitar.
