Thank you all for the advice. I think that a J bass maybe the what I am after.
May I say that this bass stuff is becoming way more exciting for me than the weeny 6 six string stuff. I'm looking at basses and doing the upgrades in my head. A high mass bridge hear , a hipshot Xtender there, and an active pre-amp to finish. Thankfully I've already got a source audio EQ2 so I do not believe that I need active stuff onboard.
Edit: With the EQ2 not being at the instrument, I appreciate that buffering is not occuring at source.
