A buddy of mine who exclusively played acoustic fingerstyle (and who builds his own guitars), just took delivery of a custom semi-hollow electric. He specified wide string spacing, closer to acoustic spacing than to conventional electric spacing. He contends that it works better for fingerstyle, and I'm inclined to believe him. I am certainly more "reliable" (i.e. play cleaner) in fingerstyle playing with that extra room. Question: Why did players like Jeff Beck and Knopfler stick to conventional string spacing, particularly after they were in a position to get any configuration they wanted?
