This is an excellent antique-style mid-range exciter, or when you're feeling abusive, great for mangling mid-range noise.
I'm not going to say it isn't harsh, because harsh is kind of the point, but it's not a gritty digital harshness; I don't find myself gnashing teeth like with many digital distortions on complex content in this frequency range. It's more of the grit I'm looking for. It does full-range content pretty well, but it shines on retro leads.
The comprehensive options under the hood make it my go to for this type of tool.
