If I connect two cabinets (1=Flextone 412s set to 8 ohms, left/mono input; 2=Rocktron 112 8 ohm wedge for a guitar only monitor) and connect the two to the two left/mono output of the Flextone II HD set to 8 ohms, will this cause any problems? In other words, if the head is set to 8 ohms, does connecting a load to the two left outputs but nothing to the right outputs affect impedence, etc? I'm trying to find a creative solution to overpowering smalls rooms versus not being able to hear myself without being dependent of the sounds guy to get the monitor mix right. Thanks!
