The D&S II accomplishes this task with some unique circuit refinements not typically found in distortions. Like a standard distortion, the D&S II features a diode-clipping stage after the amplifier section of the circuit. However, rather than using the silicon diodes commonly found in today's circuits, the D&S II uses germanium diodes in this clipping stage. The threshold voltage for clipping is 0.1 - 0.2V with germanium and 0.7 - 0.8V with silicon, so the germanium can distort even low level tones, thus making a smoother distortion. In addition, the germanium's rectifier characteristic is inferior to silicon (voltage drop with negative current is not as sharp as that of silicon) - this shortcoming ironically works favorably for the D&S II, creating a somewhat rounded waveform of the clipped signal that contributes to the unit's warm, natural distortion. Due to their "inferior" characteristics, germanium diodes are now a very rare component and have generally been replaced with silicon diodes in other manufacturer's circuits. Ironically, it is these shortcomings that give the D&S II its signature sound.
