I'd suggest asking the guys who have a tone that you like and see if you can drum up a common denominator. Who knows, it might be as simple as a change of strings to get the tone you like/seek.
Most soap bars do tend to handle low frequencies pretty well, I could downtune my Ibanez SR500 to drop C# and it still sounded nice and raunchy. I'm a big Ibanez fan (mostly based on feel) though, just felt that needed to be stated as a caveat to my advice
