lol, midrangy growl is one of those "tones" that people spend a lifetime looking for

( and I don't mean that crappy EPIphone Tbird growl either, as my Epi is my Epi, it has it's own unique tone )
if I had to answer the "what Jackson bass do I own that sounds "clean" and not growly, would be my 4B with the preamp. turn the volume knob up past 1/2 and the clean becomes a bassy growl which makes me happy.
As far as all the passive "models" I have...yep, they are not for you if your looking for a dead string bassy muffled tone as the OEM equipped non-preamped Jacksons are very bright....let the FenderFreaks have their "vintage P-bass dead flatwound tone"...I am not ripping on that or the FenderFreaks, I just don't need/want or like that "dead tone" in my daily playing or gigs. If I want a muffled bassy flatwound string tone, I'll buy an upright.
In defense of the people who like that sound, I also have a Jazz that sounds as typical as any Jazz I ever heard for those times when I'm doing studiowork on certain tunes that require that tone.
are the Jacksons one-trick rock/metal-ponies? Only to those who think so....
