on the steel thing - well, historically I'm not a real expert on this stuff - I did once have a conversation with Eddie Durham, and he said the early resonator guitars were just, really, made in an effort to be heard above the band. I think the steel body follows this, and has a different kind of resonance from electrics. The early electric guitars strike me as basically just acoustic guitars with pickups stuck on them. As players got more serious and wanted to play louder, they dealt with things like feed back by narrowing the guitar body, than playing solid bodies (some of the smaller hollow bodies are referred to as "semi-hollow" and do, in my brief experience, have a very interesting sound with the right pickups).
