I've been experimenting with using my Mark III without any graphic eq at all and I've learned some things.
For a good clean/high gain setup, you can do the following:
1. Keep the bass low so that it doesn't mush up on the lead channel.
2. PULL DEEP to make up for the lower bass and the lack of the eq.
3. Keep the treble control low so the clean sound is actually clean. You can have the volume control pretty high but treble will make your clean tone dirty and pointy at anything above 5, in my experience.
4. Since you dialed down the treble, your high end is going to be diminished. Bring it back in with that insanely powerful Presence control on the back of you amp.
5. The lower treble is also going to impact your lead gain, so bring that back by cranking the lead drive up to taste (I've got mine set at 8 right now).
It is now obvious to me that the insane Presence control range and PULL DEEP are intended for when you're not using the eq. That's probably why most people keep the Presence at around 2 - the presence control and the 6600Hz slider aren't really intended to be used together. Probably the PULL DEEP switch should be off when you use the eq as well.
Anyway, some of this I got from GJgo's post, and BigBadWolf helped me figure out how to dial in a better clean by keeping the Treble control low.
I hope this is useful to other people, too.
I'm going to play with this some more. Without the eq, the bottom end isn't quite a tight, but the overall tone range is pretty rad.
