Since I'm getting my new amp and cabinet on Friday, I'm now looking into upgrading my bass to further improve tone. I'm using an ESP/LTD B-404SM with what I believe are EMG 35 active pickups. It plays very well and I love the tone of it alone when not amplified, but the pickups really seem sterile now that I've tried out a few basses with passives.
I'm looking to get passives with active electronics that can be switched on and off.. I'm willing to try out just passives or actives w/ preamp though.
Ideally, the tone I'm looking for is Justin Chancellor's Wal

now I know you can't have that Wal tone without a Wal, but I'd like to try get closer than these sterile EMGs. Something with a bit of growl to it
What I have in mind is this:

Unfortunately, this is going to leave me with one useless knob, which is nickel plated and not black like the Seymour Duncan knobs...
Suggestions???
