I know. Most anything. Seriously, we do very well with a passport system, however we are now using the first four channels for vocals and running acoustic guitars etc.through a sub mixer into one of the stereo channels. I have an 8 channel powered mixer and a pair of 2X12 cabs - way larger and heavier than the passport. I don't want to start hauling that around. Again.
Would be real nice if Fender ( or somebody) made a passport type system with 8,10 or 12 channels. We play mostly restaurants and small clubs and don't need a PA as big as a major touring act.
