Not clogging at all! I'm sure others would be curious to hear some insight between the two as well. My take between the two leaves a couple questions. 1) How much do you value a 3-band EQ over the shape knob? 2) Are you wanting a more vintage-esque or modern tone? Those are really the two defining things between those amps to me and depending upon what you are wanting sound wise, either could work and either are awesome to me. The Root Terror has a more flexible EQ, and can be quite a bit more modern sounding. The Dark Terror is a bit more like an older Orange mixed with a modern Orange. The shape knob works really well, and really shouldn't be viewed as a downgrade from the 3-band EQ.
