I am looking for a rig that I can use for practice and small to medium gigs (indoors and out). I have a good deal lined up on a Carvin PB200 15" 160W combo. If I add a 2 x 10" extension cab, will this be enough to get me past our 2 guiatarists (moderately loud) and our drummer (also moderately loud)? Please bear with my newbie questions. Thank you. P.S. Just to be sure, the Carvin PB200 does have a line out, right?
