Well .......... I finally have it !!! I have replaced my whole rig........ I now have a Markbass LMKII , Carvin BR 210 cab , Hartke Hydrive 410 . I can honestly say the Markbass will be the last amp I will ever own. Now I'm working on a Markbass 210 & 15 cab setup. The Carvin & Hartke will do for now for economic reasons , but I will have that MB setup!!
