Hi Steve.I think the lines got blurred a few years ago. These days, the vast majority of Festivals, folk clubs (bars) and open stages that feature "Folk" or "acoustic" music, mean acoustic-electric singer songwriters. Simply the way it is.
I often have guests come on my radio show with amplifiers and various sound-processor pedals. They simply DON'T play acoustically, and seem to be lost if asked to. I just go with the flow even though it seems a bit silly to have amps in a tiny studio.
Even on workshop stages, most "folkies" plug in. The ones who don't are the Dinosaurs. It'll swing back. Always does.
