Conventional wisdom around the Brown Sound is that Eddie used a Variac to dial his Plexi down to 90v, after which he would then re-bias his EL-34's back up to normal ranges.
How does this work in the Axe-Fx III? If you decrease the Variac value, is it necessary to increase the Grid Bias value to get the tubes in the "correct" range again or is the Grid Bias control normalized so that it's always "correctly" biased no matter how the Variac control is set?
