상황
Designing an asymmetrical clipping stage to recreate the warm distortion of a tube amplifier in a solid-state pedal or preamp. The circuit uses one diode for positive signal clipping and two series diodes for negative clipping, producing asymmetrical waveform shaping.

01
Use a 1N4148 single diode for positive clipping threshold (~0.7V).
02
Use two 1N4148 diodes in series for negative clipping threshold (~1.4V).
03
Connect a 100k load resistor from the clipping node to ground to establish a bias path.
Suitable for guitar effects pedals, overdrive circuits, and preamp stages where tube-like saturation is desired without actual tubes.
