Ive actually just stopped using it and have replaced the B7K with the BDDI Sim. This seems to get me back to my old tone, but with the Fearless F112 adding extra clarity that i couldn't get before.
The only downside is i dont think the BDDI does dirt as well as the Bk7, but i dont want to end up using both, so i have the BDDI on a FS with added Drive (going up from 6 to 7.5) and slightly lower level.. I like the idea of my basic tone, but with dirt added, rather than using something that will change the tone as well.
M y setting for the Distortion in the B7k was just Drive on 5, mix/blend on 6 (this made the most difference)and the rest pretty much as it comes. I did play with with taking out the EQ and that too sounded good, but my goal was just to dirty up my base tone, rather than have an obviously distorted tone.
