Yes, that, or vice versa w/bright driver (EG - Slvania VT-107A) and warmer power tube (EG - Mullard EL34). I also find that if I am using a lower mu driver I switch to the XLR output on Super UltimatE which has higher gain..I think it's common sense to match bright drivers with warm power tubes to balance it out and vice versa....
Why do we put ourselves through all of these machinations? because it's FUN, and it sounds GREAT!
