Just read a great article in the June issue of Guitarist Magazine (UK), which shows Mr T's settings as follows (from what I can see in a partial side-on shot)
CH3 Extreme mode (I thought he was a IV diehard, but there you go!), normal setting, 45W
Gain - Full on
Master - 8:30
Pres - 2:15
Trebble - 3
Mid - 8:30
Bass - 9:30
It seems EQ sliders are on (but I'm not sure), all even just above the mid line except 2200 which is backed off a tiny bit. As I have seen him do live a few times, he rides the guitar volume to go clean to roar without pedals
I'll certainly be trying this out later this weekend
