So i just received my Streamliner 900 that i bought from the classifieds. HOLY $#@%!!! This amp is SICK. I have been chasing this type of tone for years with a Sansamp BDDI and whatever i used for a head at the time. After scouring this http://www.talkbass.com/forum/f15/genz-streamliner-600-900-tone-control-primer-813663/ for the last day and a half i took note of some popular settings and have been having a blast trying them out. Right now I'm using 11-1:30-11 (gain,vol @noon) and 600 mid. It really warms up my Schroeder cabinets like crazy! The obligatory crappy cell pic!
