Just updated my B with 5.12. I did notice that the tweaks to the O/D effect (haven't used the the others) are now more "subtle" if that is the right term. What i mean by that is, prior to upgrade i loved the sound of O/D at 7/7 with my passive J bass. After the upgrade i had to go up to 10/10 to get the same effect.
I'm not complaining!! In fact the more subtle control is a good thing, dials up more gradually i guess is the best way to explain it. Just wanted to mention so others are aware.
Good ear gl. Jim wanted to make the drives more "unity" when toggling them on and off.
