I may be wrong, but I red somewhere that the eq controls on the Noble are boost only because designed as a Fender tone stack, albeit with custom features.
So, eq controls at 12 o' clock means bass and treble boost. If you are experimenting too much fatness and bass it could be worth twisting that knobs, at least to try the unboosted tone, fully counter clockwise. In the end, that's why mr. Noble put those knobs, they are intended to be turned if necessary
I run it either way. If you put it at 12, you get a mid-notch. I like that "flat" better than starting from totally off. Either way, the bass switch left flat is more than I'm usually wanting.
