Fuzz Box Distortion Pedal – Guitar Effect

This guitar effect circuit uses a simple high gain amplification, followed by a symmetric clipping using parallel diodes clipper. The gain of the 741 op-amp pre amplifier will be R3/(total impedance of guitar pickup + C1).  With 1 kOhm guitar pickup and C1 combination impedance, the gain would be more than 1000x, this would be enough to make sure the […]
