Tone King Imperial MKII - What Are the Effects Modeled After?

Anyone know what the various drives, comp, and time-based pedals are modeled after? The manual doesn’t specify and I can’t seem to find the details. Or are they just unique/custom and not based on anything in particular?

I know, ultimately, I should just use my ears to adjust stuff, of course, but it’d be interesting to know, since, for instance, you use a Tubescreamer in a different way than you use a Zen Drive :slight_smile:
