The new gear...any tips or suggestions?

Hi, folks. Used to come here a lot under "Subsonic 6 String", and first time back in years. Anyways...

Just picked up a new amp today. Bought a Mark Bass TTE 800 Randy Jackson Sig head and a matching Mark Bass 4x10 cab (800W RMS, ported top and bottom, and attenuated horn). I play a 6-string Ibanez SRFF806 as my main bass. Mostly, I'm into technical playing, be it tech. death metal, or jazz/fusion.

I guess what I'm wondering is, does anyone have any suggestions on how to achieve specific tones out of this kind of combination?
