I spent some time in the late 70's as the bassist in an otherwise girls folks rock band. Used a showman through a 1x15. Simple, soulful and effective. The Showman was stripped to the wood cab and nicely varnished. Black face and beautiful. Wish I still had it.
As for being the only guy in an otherwise girly act ... no respect at all. The PA crap was heavy enough, thank god nobody used a Twin. I'd have had no back left at all ...
