Ok...you're going to have to increase the presence a little if you like some clarity and chime in your cleans because SG's are all mahogany guitars, no maple. On a guitar, maple adds a lot of brightness which you'll be missing. For Foo Fighter stuff though, don't increase the Presence as much, they have some "dirty cleans" at times.
Start with all the knobs facing up at 12 oclock. Increase the presence a little, drop the mids slightly, and give a small boost on the treble. Put the gain the highest it can go before the sound starts distorting. The Bass knob should be anywhere between 10oclock and 1 oclock.
This stuff is all really up to you to find what you like, but those are just suggestions for you to start with...
