I've been wondering for a while about Serum's diode distortion in general. What's it supposed to be modeled after? Are there any suitable or better alternative plugins to achieve that sound? I can't find anything about it anywhere. I've only seen it used in very specific cases for very specific sounds, but a lot of the time I feel like it's lacking something and maybe there's something similar out there that can do that type of distortion better. I know diodes are used in guitar distortion pedals, but I don't know much about it otherwise. Thanks in advance for any information on this.
