Pretty awesome reading here:
I have a question about sag
Yes, it's based on the Axe-Fx, but tons of modelers have this option, and there are some great explanations as to what it actually does.
funny I was just reading this this morning, the adjustment makes a huge difference on certain amp models.
oh and I dialed in your 5150 patch this morning too
not bad , not bad at all Mixing the 2 IRs that you mentioned made it a little less "dark"
gonna crank it after the B's game
