it sounds like it would be redundant, but it really is pretty cool having both. on the ibanez im selling, ive got the bart ntbt wired up with a passive tone and rolling off the tone makes it burpier and fartier,the treble cut just makes it more muffled.
I smell what you're stepping in...I have felt the same way at times. Since I got on the alder/ebony thing, I haven't felt like I needed a passive tone knob since the combination is dark enough by itself. When I had alder/maple basses I really did use it quite a bit.
I find the alder/ebony SB5000 to not need the passive roll off much if at all, while the stacked midrange EQ does ALOT of stuff. I find it to sound better than the same circuit on the East preamps (though not having had the Carvin out on a gig yet).
