This invention is relating to an active, all analog electronic device, for performing a controlled distortion processing over an electric audio signal applied to its input. As a result an output electric audio signal, corresponding to the input electric audio signal is produced. The output electric audio signal is distorted, and contains the dynamics, harmonics, phase shifting and time relations between the components of the input signal. The Method of Analog Math Processing for Controlled Distortion of an electric audio signal and Device consists gain, gain controlling, signal attenuating, buffering and summing stages, blending, tone and level variable controls. The summing stages are arranged to receive signal portions from the gain stages, through their corresponding attenuating stages. These signal portions are summed, based on the analog math processing principles and a distorted electric audio signal is produced with a wide range of smooth and controlled overdrive and distortion effect.

This invention is related to a magnetic pickup device for stringed musical instrument with one or more metal strings made by magnetic permeable material. The magnetic pickup device presented comprises of at least one signal picking coil for sensing of the mechanical vibrations of the strings and at least one large free shape low impedance coil for noise cancellation. The signal picking coil and the large noise picking coils are permanently connected in series in a way that the noise signals created by the two coils have opposite phase orientations and they effectively cancel each other.
