Just got my new Silver Jubilee head today. I have 2 1x12 speaker cabs I would like to use. One cabinet is a 16 ohm Mesa Boogie. The other is a 8 ohm Orange cab. My question is, is it possible to run both cabs at the same time? Which speaker outs would I use? The 2 8 ohm outs? Or the 16 ohm and one of the 8 ohm outs? Thanks.
