Songbob, I was the one who asked the question about the angled bridge.

What made me think of the question was the Martin Backpacker which comes in a classical and a "standard" (steel-string) model. As far as I could see the bodies are the same and neither has a truss rod, so I wondered if you could buy, say the classical one, and then put steel strings on it if you didn't like the nylon sound. Your comment about the scale is one I hadn't thought of. (actually I don't know if these two models of BPs have a different scale.)
