A friend & fellow bassplayer is obsessed(his words)w/the idea of a battery-powered amp. I have skimmed through some old threads on the Breifcase; there doesn't seem to be a lot of info regarding battery-powered use. Also, at 100 watts, it doesn't seem to me that it would be capable of competing w/much in the way of other instruments. My friend would like to be able to pack a small combo out to a camp fire or similar setting & not get hammered by the g*****s. Is this feasible(w/the PJB)? I'd really like to hear some first-hand experiences. Thanks! BTW, the Crate Taxi is pretty much useless for this application, isn't it?
