Thankfully, we all know that as Curtis learns and grows, he will discover a different sound... and that in the end, although he may find his "main" sound, he will not have just one sound.
Man...
I'm just showing my age here, but to me, CRUNCH sounds way fiercer than scooped distortion. I like to hear at least a wee bit of what the 'clean' tone would sound like, if you know what I mean... I realize that you don't really, but... well, I think some people know what I'm getting at. The Queens of the Stone Age are super badass, and their distortion isn't full on by a long shot.
Boost them mids, rather than scoop them. Drop the gain. Keep some treble in there, though; and Bob's your grandfather's other son.
