So getting a little practice combo/rig. The head I'm getting is the GK 400RBIV. No what I'm not sure if I should even bother on is getting the GK400RB 2x10 combo, or looking into Avatar/Dr.Bass cabs and getting the head sepearatly. I heard round here that GK speakers in the 400RB combo's are the greatest. what do you guys think? should I get the combo, or get a sep. cab/head ?
