6strings

It seems that all 6-string Warwicks use the same Active 6-strings humbuckers. (Except the two 6-string streamers in the custom shop which use active Js...) Are there any 6-string passive pickups in the list of pickups available through the custom shop? are there Twin Js or Ps in passive 6...

I have a Rockbass Corvette 5-String fretless, and now it is my main bass...however, I like to play 6-String fretted basses, and I would like very much to buy a Rockbass Corvette 6-String, except by the fact that it does not exist. Is there any plan to produce such beauty?
