Descripción: Disortion pedal

The Maestro Fuzz generates low order harmonic distortion for guitar, Bass and other electroacoustical music signals. Specifications for the Maestro Fuzz include: Input Impedance........1 megohm Maximum Recommended Input Level..........OdBm Output Impedance......20K ohms (maximum) Maximum Output Level . . + 5dBm Equivalent Input Noise ... - 1OOdBm Type of Distortion......Low order odd harmonic Power Requirements.....9.0 VDC at 250 microamperes Recommended Battery Type...............NEDA 1604 Estimated Battery Life ... 3 months CIRCUIT DESCRIPTION The Maestro Fuzz, powered by an internal 9 volt battery, generates low order odd harmonic distortion by using silicon diodes in the feedback circuit of an operational Amplifier. Refer to Figure 3 for the schematic diagram. Either the fuzz mode or straight Guitar is selected by foot switch SW1. In the fuzz mode, the input signal from AXE jack J2 is a-c coupled to inverter IC1A, the output of which feeds DRIVE pot R6. Since the distortion circuit following R6 is level sensitive, R6 acts as a distortion amount control. The distortion circuit consists of IC1B, CR2 and CR3. Diodes CR2 and CR3 in the feedback path of IC1B cause symmetrical clipping of the input waveform generating the desired distortion. The distorted signal is a-c coupled to VOLUME pot R9 which controls the Maestro Fuzz output level. In the straight mode, SW1 shorts the Maestro Fuzz output to ground minimizing fuzz circuit bleed-thru and the input signal is connected directly from AXE jack J2 to AMP jack J1.
