I have an SV 112 and an HD 100 with a bogner 212 cab. An easy fix is to go through and reduce all of the channel volumes of the patches you use on your gig.
At first I was having to run the master at about 1, with my channel volumes around 90%. Over time I lowered all my channel volumes down to between 15% and 25%, and now I run my master at about 6 on the same gig. The sound is better.
