Distortion effect with diodes and transistors

With this distortion effect, an extremely distorted guitar sound is possible:

Using this effect devce, the lead guitar playing results in a soft sounding. By appropriate playing, it sounds reminiscent of string instruments and you get a lot of sustain. The comparatively low-impedance input flattens the frequency response of the guitar pickup, wich creates a synthesizer-like sound impression. Due to the high gain of the circuit must be paid to good shielding in the guitar electronics, the cable and the construction of this circuit, otherwise hums occur.
