I've had my Bass Muff for more than a year now and got a Stingray a while back as well. I always use the Dry setting and got the tone at around 1 o'clock; this setting DOES make the distortion get slightly buzzed with the guitars, but you can still listen to it thundering in the background.
I always use my volume at full, boost the bass, cut the mids just a tiny bit when playing with a pick (Leave'em flat when finger picking) and boost the highs a slight amount. You should have no problem with it.
