Abstract
A preamplifier adapted to receive audio frequency electrical signals generated by a musical instrument for providing controlled output signals therefrom having selected distortion and harmonic signal content is shown wherein the preamplifier includes an amplifier for amplifying audio frequency electrical signals generated by the musical instrument, a first electrical signal processing channel operatively coupled to the amplifier for receiving the amplified audio frequency electrical signals and for producing in response thereto a first controlled output signal wherein the first electrical signal processing channel includes a plurality of selectively interconnectable signal processing circuits at least one of which is capable of at least one of selectively amplifying, distorting and adding preselected harmonic content to the first controlled output signal, a second electrical processing channel operatively coupled to the amplifier for receiving the amplified audio electrical signals and for producing response thereto a second controlled output signal and wherein the second electrical processing channel includes a plurality of selectively interconnectable signal processing means at least one of which is capable of at least one of selectively amplifying, distorting and adding preselected harmonic content to the second controlled amplitude output signal and an output circuit operatively coupled to the first and second electrical signal processing channels for selectively applying one of the first and second controlled output signals to an output terminal is shown. A method for providing controlled output signals having selected distortion and harmonic signal content is also shown.
