Well, a Brown Bass would have no maple at all, the dominant wood is mahogany, and I would assume it has a set of Fatboy pickups, and no onboard treble boost switch, so not surprising there is less apparent "snap" than on a Distillate. You now have two volumes and two filters, so way more options to experiment. Looking at the WD-800 specs, you have a megaton of EQ options there, so again lots of room for adjustment.
My 6er is sort of based on the BB wood recipe, and I find I use the neck pickup as a kind of subwoofer that - with the filter nearly closed and a dallop of Q - I can turn up to shovel in some heft along with some dry woodiness, whereas the bridge pickup volume is on full, its filter is at like 80-90% for slightly sweeter highs and perhaps a bit of Q as well.
If you're using nickelwounds, a move to stainless might help. DR Hi-Beams or Lo-Riders will also retain their brightness longer than Rotosound.
