I picked up a 2x12 LSS combo recently for gigging.It looks like its a few years old.Still in good condition but certainly isnt fresh out of the factory by any means.My plan had always been to get the 2x12 for recording as it sounds bigger than the 1x12(had a 1x12 before) and then rack mount the chasis for gigging,due to the weight of the 2x12.Im about to pull the trigger on the rackmount kit and a flightcase to rack it up in,but im wondering if the power tubes will be a bit exposed, as the power plug could be loose in the flightcase and bang off them.My special doesnt have the tube protection cage or any slots to mount one in it.The rackmnount and 2x12 pics on the mesa site currently have them.Is this a feature they added to later models?Cheers
