I see you have turned your bass low.
Try this: Turn your volume(first pot on the left) up to 6-7.
Turn your presence all the way up. Adjust your tone controls to your likings.
Fine tune the presence.(set fairly high).
I tried this -
volume 6
presence - full
started with BMT all at noon.
bright off (I can't imagine a case where this is even needed!) deep off rock on
have the ratio/level at 3
master at 2
still way to much sizzle - even with the presence off it is way bright and the OD seems sizzly/fizzly, bass is farty. Lower bass to 2, still not good.
