Yeap.
It is a DOD Grind distortion: A noisy (in the bad way), inexplicably low-output OD/distortion. For many years, I was disappointed that it wasn't another Grunge, Death Metal, Corrosion, etc. I eventually came around to it, though, once I learned to understand it a little better. What it lacks in "DOD-extreme" distortion and decibels, it makes up for with a rumbling-yet-defined low-end boost (the low EQ is even labeled "RUMBLE"), with enough treble on tap from the high EQ to give it some compensatory grit.
